Fantastic amps. I have a HD-150 and it’s a monster. 1x18 and 4x12 cabs. I run a Baritone through it and it’s absolutely brutal. This is amazing that you’re repairing these. We need people like you in this world! A dying breed
i got a 2x12 75 watt musicman. it rules. it's survived being tossed half way across the club, and also got hit by a cop car through a wall, and it still works and sounds amazing.
I wouldn't mind at all having a Music Man amp if I had someone locally of your expertise to keep it fresh the way you do. Shipping an amp across the country, along with the risks and potential for causing additional problems involved causes me to remain in awe of your work instead of owning some of the amps you keep going so strong. Thanks Colleen.
I used to have a Music Man 65 head about 8 years ago, but I traded it for a Quad Reverb. I love the quad but i do miss the Music Man a lot. I used one on a recording a couple years ago and it made me want one again.
Love the video! As much as the nerds of us want to see an amp being repaired, we also need to hear it after 😂.... We are addicts. Please give us our fix.
I had a Music Man and I loved it! I hated the bass and treble boost, but I could get an almost Eddie Van Halen tone out of it. My drummer got mad one day, and decided to pour a beer all over my amp, and shorted out the transformer. My amp repair guy told me that the transformer was "half blown", meaning that he could return some functionality to the amp, but it wouldn't be the same. Miraculously, he got it to work good enough that it was able to do what I needed it to do. I let my friend borrow my amp, and for some reason, he decided to pull the tubes. I guess the tubes in a Music Man amp have to be pinned out in a certain way, and they don't have the guides things that a 6L6 have to ensure you plugged the tube in correctly. Long story short, it died. :(
I have one of these. When I got it, it was noisy, which I figured out was a cracked solder joint on the low voltage board. Thankfully just had to reheat it. I learned a lot on that troubleshooting mission.
From watching your videos I got inspiration to build my own amp ,Trouble is my neighbors are mad at me because when I turn it on all the lights in town go dim and people said it cracks their windshields 😮 but I think having 200,000 watts of power is really cool 🤓
Bought my MM 110-60 many years ago, like 1980?, other than a reverb and tremolo issue, reverb was a bad wire from tank to chassis, tremolo was likely arcing in circuit board which a shop fixed. It still works fine, and I like it still. Have fun
The boards on this stuff are always a treat to see, because all the traces and stuff look funky, like a human probably laid them out on a piece of paper. There's all these swoopy shapes in the traces that you'd never see on anything modern.
Oh yes, yes. A lot of my mentors used 'em. I think someone shared that the plate voltage is up there. Clapton fans loved them back in the day. Thanks for sharing
These were factory equipped with Sylvania fat bottle 6CA7 tubes (a ruggedized beam power tetrode version of the EL34 pentode), and the current was set very low, almost in class B mode which is how they got away with running something like 600 V to the plates.
On my old HD 130 4/10 Music Man my tech told me that the plates on the el34s had 470 volts DC. I've heard that some of the music man amps can have as much as 700 volts DC on the plates
Old MusicMan amps are very cool! My brother has 3 of them. A 75 combo and 2 heads. 70's 80s R&R, southern rock, can't do better that MM. Great Duane sounds
I've got that same model 2x10 65. I bought it new in 1977 and just had my amp tech in Muscle Shoals service it. Great amp. Thanks for the great videos !!!
I had one of those! Loved it. It took the early ,few, distortion pedals very well. It was very loud and very reliable. Everybody looked at me sideways because of the 10 inch speakers,until they heard it.
I have an 210 HD-130 combo with 12AX7 as phasesplitter and it works fine and sounds so good . Original speakers are gone but I replaced them with 2 new Eminence Legend 1058 speakers. A small but heavy and mighty amp ! Great for real clean tones at high output.
I played someone's old music man 100 watt head and it was so loud it hurt. Looked just like that head up on top. Brutally loud and I don't know what speakers he had, but they were moving some serious air. You could feel the pressure all around you. Impressive amps.
Absolutely love your channel and your skill, just one thing.... I think the 12AX7 is the phase inverter which got changed to transistors in around '79. I may be wrong and apologies if I am.
I used to work in a local music shop fixing amps and guitars and other music equipment, but the owner of the store retired so that was kinda the end of that. But I still fix some music equipment once in a while, I fix mostly cars and riding lawnmowers 4 wheelers and pretty much anything people bring to me. But I manage to make a living doing it so I'm loving doing it because I'm my own boss. So what circuit was that "death cap" a part of? Cool Eric Clapton tune by the way.
I’ve got the HD 2x10 dual power. It’s a beast, the tremolo is amazing as well as the reverb. It’s loud as hell and very clean even though it has the built in master volume. I like it but it’s definitely not as collectible as the old Fenders…most of which I’m fortunate to have in a collection. Sooo glad you’re here in So Cal Colleen.
I gigged in the late 80s with a MM 210 Sixty Five. Loved it and still have it. Sounded killer with a Boss SD-1 in front of it. Like a mini yet more flexible Twin.
Nice ! This may come in handy - I've got a 112 RP 65 sitting around from back in the day that I've been meaning to get to (DIYer who's only worked on old Fender Twin and Vibrochamp). Internal markings indicate mine's a '79. and Its even more "hybrid" with 2 GE EL34's, SS pre with a bunch of IC's + a built in phaser. Made a horrible very loud noise last time i turned it on. Found a broken lead on the big silver power supply cap, but after that who knows. Bookmarking this one Thanks!
Almost bought a Music Man when they first came out, ended up getting a boogie mark one instead… I kept it for decades and had to sell it when I fell on hard times
Nice! I had a MM 112RD Fifty combo amp years 40 ago. It had a great clean sound, but not gritty enough for me at the time, and I was stoopid and did not know enough to try an overdrive pedal. I traded it and a '73 Strat to my brother for his '64 Chevy Chevelle Malibu SS convertible (it was a bit rough, but fun) because I needed a car. That car rusted out and is long gone, but he still has the amp! He sold the Strat a long time ago, and it has vanished into the Ether. I've been looking for it.
I still have my Music Man HD 130. Its been all over the country with me. I bought new , its currently running 5881 power tubes . I'm going to take it back to 6l6's sometime in the future.
You're a little gem Colleen ... I doubt if there are any other gals in the world as clever and good looking as you are sweetie ... I will admit though I am one gal who can follow you with no trouble at all ... I can understand everything you do when fixing these amps ... good work honeybun 👍
The worked great with the few effects we had then. I got a great distotion sound with my now obscure Ibanez overdrive 2 and my morley power wah . Great times.
My mom bought a 2x12 (HD something) musicman for 75 bucks at a yard sale. It sounds great. Like a Twin Reverb that you can dial some hair into. She is right about them being finnicky--you can get a bad sound out of them.
Awesome stuff, really impressive! I'm changing a resistor in a Peavey amp. As far as I can find out, it's a 22 ohm 1 watt resistor. Can I use a 22 ohm 3 watt resistor as a replacement? Thanks!
Yes, as long as it fits in the space. The watt rating is the maximum the resistor can handle. 3 watt is more than you need since your amp should be running well under 1 watt through that resistor. If that resistor is one that often goes bad in that Peavey, the 3 watt should hold up really well. Running a resistor near its limit will greatly shorten its life.
I tried rebuilding the lans as they were burnt and lifted off the board probably by the store I bought it from used trying to fix it. By resoldering joints. They didnt. It had multiple problems. It wasnt solder joints, but was jacks and caps and pots. Instead of trying to glue down a new lan, to much trouble and is difficult and doesnt always stay, I use the hard wire method too. And thats on digital boards.
I'm collecting the Fender ""ii"" series of amps, was wondering what you thought of them. The ones I have were all made the same year I was. They speak to me, I dunno. Very little info out there aside from the Princeton ii, and mine is MINTY fresh, so I've never had a reason to look inside it. New subscriber. Good stuff.
@@robertcalvin2643 Yes.👍 Just watched a really good video covering all of Leo’s bass guitars from early Fender through G&L. Didn’t remember that he had a stint at Music man prior to G&L. Good stuff.👍🎸🥃
Both Eric Clapton and Mark Knopfler used these amps back in the day. They were seen as more powerful and tougher, but had less character than Fenders. Very direct and a bit sterile without some effects added!
well i came to this vid on the year stated of the amp. im all most 100% certain that musicman went to the solid state driver board in mid 75 phasing them in and fully in 76. along with the badge color flip change. i have a late 75-76 with the same black on silver badges but mine has the db1 driver board. those was put in place of the 12ax7 so that if something happened to the output side, like the phase tube or so went out, then you wouldnt fry the out put trans and tubes. im looking for a better quality schematic for these as my eyes are getting tired. any help with a good set would be great. my hd130 has developed a reverb issue thats annoying to say.
Is there an electrical and/or circuitry reason why you replace the high voltage before the low voltage? Also, thanks for clarity on the birds; just before you showed them I was thinking, 'man, that's some weird generator noise in the background'
I played through and sold music man amplifiers around 1977 1978…! I always thought they were great amplifiers …👍🏻👍🏻👍🏻 Being an old musician, but still functioning at ( 70 ) 🎶😳🎶 , I have probably played just about every amp that was popular at one time or another on stage and on the road….! One amp that I was always amazed with …, is I had a Peavey 6/12 with a Horn roadmaster…🎶👍🏻 this Amp was loud as ALL GET OUT..! 😵💫😳 It was a real bear to haul around…! I was wondering if you had ever had a chance to work on one of those the full stack and play through it …?? ( The Jeff Galey Channel )
I had an HD212-120, which the sales staff talked me into buying instead of a Fender Twin Reverb. I regretted that decision until the day I sold the MusicMan. I never liked it; it had no character and no sparkle.

I know how much these amps vex the technicians, but they're absolute gold for players. Loved every one I've used.
Love the video! As much as the nerds of us want to see an amp being repaired, we also need to hear it after 😂.... We are addicts. Please give us our fix.
I’ve played way too many amps for someone of my (lack of) talent, but the phase inverter MM 210 Sixty-Five is the combo I’d save in a house fire.
I had a Music Man and I loved it! I hated the bass and treble boost, but I could get an almost Eddie Van Halen tone out of it. My drummer got mad one day, and decided to pour a beer all over my amp, and shorted out the transformer. My amp repair guy told me that the transformer was "half blown", meaning that he could return some functionality to the amp, but it wouldn't be the same. Miraculously, he got it to work good enough that it was able to do what I needed it to do. I let my friend borrow my amp, and for some reason, he decided to pull the tubes.

I've got a Music Man 212-65 with 2 12" JBLs, and it sounds incredible with my Strat in between the back and middle pickups!
You sure make amp repair look easy. Thanks for sharing your knowledge with us.

Back in the day when 65 watts meant RMS and not 5% distortion or peak. I still have a couple MM amps today. Great work Colleen.

Mark Knopfler used them on the first two Dire Straits albums. 'Nuff said.
I have quite a few MM amps. They are great.
I use to have an amp just like that. I took the stock speakers out and put in JBL D110's. It sounded glorious.

What a great job.
these sound great, i knew a wonderful blues player who used an MM head thru a Laney 4x12, killer tone.
