I have a Line 6 Catalyst 60W amp that I would like to convert to an 2x12 amp. The Catalyst have an 4ohm speaker now. If I connect my Catalyst to a cab with two 8 ohm speakers in parallel will that work like now when I have one 4 ohm speaker connected?

I've so far resisted turning this into a Champ/Princeton, wanted to give Laney their due for whatever they had in mind design wise. I put a switched B100k pot in line with the NFB white wire, left R22 be, I get about 100K total just switched on which is pretty greasy, switched off I get all the noise. Riveted a 9 pin tube shield base right to the chassis, the tube sits a touch lower relative to the shield but there's so much less input hash isolating that 12ax7. Cut the trace from the 22uf screen grid cap and installed a 470R screen resistor. Recapped the psu and the power tube bypass cap with the Taiwanese Supertechs, just to get rid of the sketchy chinese caps. The only surface mount meddling I accomplished was to parallel a 68K across the 68K input grid stopper to get it to 34K. The best change was a 60's Rola 8" ceramic, so officially it's still Celestion loaded but not with a speaker ftom the Celestion toy department. I tried a 50's Heppner 8" alnico but the circuit voicing didnt suit it. Then good tubes, stuck with old stuff, a USA Tung Sol 6v6 and a late Westinghouse 12ax7. Rebiased the 6v6, made a 400R resistor, got it to 12.1 watt plate dissapation. Tried a Russian 6P6S, didnt care for it, I think it needs to be biased at its 13W total pkate dissapation. Could have a switched bias resistor I suppose 2x12 ceramics is a different story! I have a couple 60's Jensen C12R's in a cab, they're fun with this. Mine is a 2019, not the TV front like yours. There's a 4 ohm tap on the output transformer that doesn't have a lead, easy to add the lead & an additional jack or a switch. I like it's not a Champ but I'd appreciate a spongier psu. I might add an EZ80 hybrid rectifier with the diodes or just a straight EZ81 if I get ambitious. If I do I'll likely ashcan the pcb, install tag strips and handwire it all. The mdf cab is okay but it really needs a plywood baffle the keep the speaker from mooshing out.

I've had a DG80 and a Dg100 for over 25 years. I've tried every modeling amp out there (except the Kemper) and the Yamaha's, IMHO, are still the best sounding of the bunch

NO! I want to KEEP my combo amp speaker and add an extended 1x12 cab. I don't want to cancel out my combo speaker.- play either/or, I want to play them both at the same time.

what do i do if my distortion isn't working

I have a question can you use PA speakers, external cab for electric guitar or acoustic?

What potentiometer did you use as a replacement? Where did you buy it? My sister's amp knob got broken by people helping her move.

GRACIAS😄

I have a fully working 1963 harmony H-802 sunburst I bought it from goodwill over 20 years ago and it has just been sitting there ever since ,it came in the original cardboard box with the label of an old phoenix area store decades ago called Fedmart with 1963 printed on it

My Marshall gfx 30 stopped powering on It has a rocker switch Where should I start to figure problem out?

Whatsup man! I am looking to strip and repaint my fender squire. If you are still active on this account i would love to talk to you about the process! Thanks!

Hello super intrusive, we need translation

Of course tone is subjective but i bought one of these teal stripe bandits a couple years ago after trying the Blackstar id core and the boss katana and not really being all that impressed with either one of them but once i bouth the Bandit and i paid $240 for it, it became my favourite amp ive ever had i consider it a solid state version of an in between JCM 800 and a 5150 tone, ill never sell mine as i find the amp to be exactly the tone i always wanted, and yes i love 80s hair metal tone so thats probably why

I can't believe you fixed that whole guitar and then picked it up and started playing The Beta Band. Well done.

My amp is making like obvious static noises and the amp makes a noise when I play the strings (static scratch noise) but not the actual sound idk what to do!?

I LOVE Crate and Peavey solid state amps. If I ever see one of these for a good price I'll buy it.

When you first played your amp it sounded exactly like what my Express sounds like now. You have inspired me to fix my one up.

The moral of the story is to clean your pots once every forty years. Good job. I just got a Peavy, too. Seriously underrated.

i cant subscribe..

By the way, this is a true stereo amp with two discreet channels. Behringer was one of the few companies that made stereo amps that gave a much wider sound field through their two speaker combo amp cabinets. Also I noticed when you were testing the amp you only had one channel under load at a time. This 'could' cause the opposite channel that isn't attached to a load when the amp is on to burn out the output transistor for that channel. Correct me if I'm wrong but I believe that is the correct assumption on my part. You're fortunate that this didn't happen to you.

believe me, best amp that i own. i have reached the peace for distorted sound :)

I use Cockpit spray to clean the cover. I disassemble all metal parts and wipe them with a damp cloth. Then I make it really dry...And then cockpit spray. Shines like new...and really good :-) Massimo :-)

Dave..are you on Facebook? I want folow there too :-)

What if someone lost the power cord. Is there a way you can make one for it

Hello...are you on Facebook?

Zoom out, and focus! Where is the power transformer?

Dave I am working on one of these XR684 units. Needs new XLR connectors as these are worn., Have you ever tried replacing those??? I have it apart and the connectors ordered from Full Compass.

Dave where are you and when is the next video?

Tengo una consola de esta, funciona pero mantiene la lámpara en serie un poco ensendida es normal gracias

It's a Danelectro made Airline. Original baffle

Speakers on This are plug ? Cpnection

I have the UNIVOX version and yeah, it is missing the Lafayette HF control knob. Mine has all sorts of half-assed repairs, missing a ground, etc, so thanks for the reference video.

Here I am 4 years after this video was uploaded to say I would not do anything to the cabinet except maybe replace the handle. The wear and tear gives it character and is part of the amplifier's history.

The fan does not come on at power up. Or it would stay on all day and night. It comes on at just past running temperature. Every adios amp is the same. Nice video though.. peace

Always loved these when I was younger, nostalgia haha thanks for sharing!

Hi Dave, great video! Thanks so much…I have the same amp and I love it. Got question about what tubes yours has? Mine has an 6sj7 and I’m reading on line that others have a 6sn7 or 6sl7 witch is grainier I also read that a 6sn7 can’t be swaped for the other two. Sorry for my limited knowledge I’m doing my best to learn Thanks for any info you can provide Regards Sam

All things considered , best amps on the planet . USA made , indestructible , great sounding .

Thanks Dave, I have Stdiou pro 110 with the same problem, I hope to fix. 😅

I think the RCA manual said not to go so big on that first filter capacitor has more to do with not killing the rectifier tube with a huge inrush of current. With diode rectification, that’s no longer an issue

Thanks for your demo Dave. I have been having trouble with my Crate TD-70 dropping out and noted that the channel changing lights were changing or dropping out without pushing the button. Did a basic clean with electrical contact cleaner which did not solve the problem. I note that the loose connection you repaired is probably where I have to look next. Cheers, Chris Mac (Australia)

Nice. Thanks for sharing.

Hey I was wondering where you ordered your parts for your Behringer gmx 212 v tone amp I need the input jack repaired and I need to get shafts repaired like in your video and would love to know where you ordered parts from so I can repair this wonderful Behringer amp I got

Thanks for the video. It was very helpful. I just bought an Express 112 for $50 Canadian which is currently $37 US. It works fine but I did the same thing you did, disassembled it, cleaned the pots and switches and the tolex.

Not getting a picture. But I have a br6-f I love it they were actually given out in schools when you bought a lap steel guitar along with it. My dad had one and I was told my uncle sold it for a case of coke. 2 years ago 15 years after he died I found it in the attic. It’s my favorite amp

Love Begringers. I am in need of a knob for my ACX1000. ANy idea where I can find one?

Heya my behringer gm110 turns on and has no sound but if I switch it off it plays my guitar for a split second

This was very helpful. Thank you!

Awesome Job!

I think California is a Mesa Boogie? I have the gmx210 and its amazing honestly I love the vintage Jensen 10" speakers!

Great video! When you first described that the amp was reported to cut out, I thought that it would either be the Insert jack (effects loop) or the Extension Speaker jack. On these amps, the extension speaker jack is connected in series with the internal speaker (which means that if the switching function of the jack is dirty, the amp will cut out). I have an XT65R which is a generation or two before this amp was made (as it just has Reverb rather than a bunch of effects). I bought it new in the early 2000s and it remains in the stable. A lot of amps have come and gone, but the humble little Crate remains. Great clean channel and a very Marshally (to my ears anyway) Rhythm channel.
