This makes me glad to have sold my Mesa. These days, I'm playing Mojotone 5E3 and 6G3 Deluxes. They sound good! The construction is like what Leo did in Fullerton. Mojotone went to some lengths to re-create those amps. I like the cloth covered push back wire. There's some extra satisfaction in playing a Warmoth guitar you built through an amp you built and gigging with them.
Those AC plugs are an IDC design, for Insulation Displacement Connector. A variation on old-style telephone and data connectors where the *solid core* wire is pressed into a forked tab which slices through the insulation. Not a great design for 120 volts however, especially with stranded wire and a fan motor that might have an inductive surge at turn in. Okay for replacing a plug on a table lamp, I suppose, especially if the lamp uses an LED bulb, but a 100 watt incandescent bulb might pull enough current to overheat the plug, especially the original cheesy right- angle plug that you replaced.....BTW, I bet I have some of those square courtesy outlets!
That was a fiddly little repair with that fan plug..! For such a big named amplifier, you would think some form of different connection would have been easier with the design.! Nice one though Lyle..Ed..uk..😀
Thank You for another great Mark IV vid .....so i got one Mark IV B ....and just recently had a issue the Main Output Level / Recording volume pot is doing nothing also the Lead Drive pot isnt aparently effecting much .... any corelation between these two pots effecting one another or just my bad luck and need to replace these two ? ......any source you could recommend for replacements?
Have you heard of many amp techs simply refusing to work on Mesas any more due to the various hassles involved in servicing them? Bias issues, confused layout, and obsolete parts aside, it seems doing even basic maintenance on them involves disassembling half the amp to get to trouble spot. Regardless of tracking down replacement parts, just factoring in the hourly bench rate alone must make them some of the priciest amps to need work.
Oh, and it’s not just Mesa’s. The Peavey Classic and Fender Bassbreaker are a few more that are stupid impossible to fix under the value of the amplifier.
Crappy lamp cord cap time. You have to split the zip cord back about 1/2 inch, and you do not strip the wire on those. Those spikes dig into the insulation, and yes, it's hokey as _____! The ribbed side of the zip cord is supposed to be the neutral.
Ex- IECA, IBEW, IEEE, NEMA, and a few others. I quit paying my dues. It's like the neon sucker sign on my forehead. After I missed 4 payments they repossessed it.
Hi, I own a Mesa Boogie Mark IV combo amp, can I run it without the fan turning on? Just for playing at home at low volumes, I don't like the sound of the fan continuosly on. Thanks
@@0megalul309 I have owned and repaired more Mesa amps than you most likely have. And yes, I can afford there amps. I am not going to start a pissing contest over your comment, but your comment is simply argumentative and not true.
@@fiddlix I just pay to send them to mesa to fix. No need sending them to incompetent techs who probably make comments like throwing them in the garbage due to their inability to fix them. 🤷 There's a reason why people still buy and maintain these amps after 30/40 years but just cos of subpar techs they get a bad rap lol. You don't send your sports car to the local hippie to service it and the same thing applies to most modern multichannel amps that cost north of 2000 USD.
Statement from The Indignant Englishman "Mesa??? No, Sah! Never, Sah! Not on your life, Sah! My card, Sah... Good Day to you, Sah!" Mesa looks like A Hunka, Hunka Burnin Junk. I never liked their amps, but all of the Mesa repair videos I've seen on RUclips confirm that they are poorly designed, overpriced and hard to repair.
I've got one of those outlets for sale but it comes with a Mesa Mark IV attached.
I appreciate your level of professionalism Lyle.
Mesa amps are agnostic Lyle. They are still questioning if amp designers exist at all...

Still love my mesa amp. 25 years and never been to the shop. I probably just jinxed myself. Also as others have pointed out, look up IDC.
“Class A………as if…” Lol!!!
how good did it feel to CUT through those wires!!!!

From my experience there is no need to strip out the insulation for this type of replacement plug to work. I believe it helps as a strain relief.
I looked at the plug closely - the contact points were not sharp.
@@PsionicAudio understood. sometimes ones have to be there to know best. right?
The stock one had the little cutting contact surfaces.
i found two salvaged 1.25" square power receptacles i sent you an email. i also heve a 1" sqaure one

Yes. I refuse all but the earliest Mark amps. When I do find time to advertise/work on amp that is.
Oh, and it’s not just Mesa’s. The Peavey Classic and Fender Bassbreaker are a few more that are stupid impossible to fix under the value of the amplifier.
I refuse to even try one out for these reasons. If people quit buying garbage it won't be manufactured. The whole tube bias thing is enough for me.
Good job.
got a nice raunchy sound
Half of that is the lav mic clipping.
@@PsionicAudio Ha!

I know all that, but it didn't have spikes. Had to strip the installation back on this one. Trust me. I was there.

Yeah you can just unplug it. It’s not really needed if you’re playing for a few hours at a time with the master down at typical levels.
What will fix a Mesa amp is to throw it in the garbage.
Lol!
Hehe
pov you can't afford one.

AHAHAHAH! Your turn this week!
RIB use those plugs in their power supplies. A very dangerous component. The amp is better off without.
I’m so never buying a Mesa, to think I so wanted one. Lol
same here

I'm glad I never bought a Mesa. Never will
7:00 out of frame dude
That's the sketchiest plug setup ive ever seen.
