I don’t see a problem with it provided the mod is done well, but there a lot of shoddy workmanship out there that will ruin an amp. If everything’s way out of spec I’d just put in a new board loaded the way you see fit. Then you can swap it back to original if you sell it to the tan pants.

Man I’ve wanted to build a Cameron for a while now but could never find a schematic, now I understand why. That things a nightmare inside. Very cool to see the “Jose” caps though. Might have to give that a try.

I look at it like this, we know vh wanted distortion at lower volumes as did everyone of that era. And he was sneaky and super protective of his tone. A master volume on the back of the amp would do both for him, and it being on the right side would allow him to fiddle with it while playing...

If memory serves me correct whoever produced that album said he did that song in one take. Absulutley insane

Maybe they say things differently across the pond but I think it’s gotta be a long tail PI given everybody’s used one for the past 70 years of amp building. There’s not a lot of room to reinvent the wheel in terms of phase inverters.

Not sure who designed them, from their catalog they say it’s for punch and generally sounding big. You might find this interesting, it’s from the 84-85 catalog. THE HALF-BACK CABINETS Two-Twelve and Four Twelve cabinets have been around for a long time. But if you think MESA/Boogie just...

Im a big “amp feel under the fingers guy”,there’s a lot to it but it’s a squish and bounce thing. I think a lot of it comes back to the tonestack, and which style you prefer. It’s the same reason why some guys say a Marshall is hard to play, while a fender-ish amp might be easier for them. That...

Absulutley, I haven’t played the cool shit like you have but I feel like the mark 3’s ride a fine line of gain and harmonics, and your always battling the 6600hz slider vs presence. Given that guys ears I don’t think he can do much wrong.

Herm modded 2203 would be my pick for things that actually exist. If I could have one to rule them all it would probably be a hermansson modded boogie mark coliseum, while it doesn't exist it should.

For a modded Marshall thing I’d go Hammond/heyboer. Personally I have some Hammonds in my clone and it’s spot on. And as you’ve seen by now nobody has a bad thing to say about heyboer either.

Heyboer/Hammond are kinda the gold standard. Not the pinnacle but still very good. Can’t go wrong with either. Mercury if you want high plate voltages and dc taps. But they’re expensive Merrins are the closest clone to the originals but if memory serves me correct your gonna wait a while.

Add a loop, they’re about $70 and not really invasive. From memory it’s like two wires going to pots and one wire for power. Wire it without an on off switch so no holes are necessary. Anyone who complains about a metro or headfirst style loop on an 800 should be beaten with a fretless wonder...

I think your right on, to me it sounds like a tube issue. Only thing I’d do is open it up and look for any burnt (like you said), and post the pics here. Then swap the tubes and fire it up while it’s open. Provided nothings burnt, odds are the fuses will save the important bits.

What’s your budget? And I’m assuming you want one already built? It’s hard to say, I know a lot of people complain about the transformers in the Ceritone clones, and how expensive shipping is from SEA. Only downsides I can think of is 800’s are not especially tight stock, nor do they sound very...

This might also be helpful if your a visual guy. Especially setting up the master vol.

Looks like a post phase master and the switch is for something to do with the NFB (maybe) and under the heat shrink looks to be something other than the stock NFB resistor. Not super familiar with those boards tho

Looks a little short to me, but you’ve owned a few more of these than I. Edit: never mind, that’s considerably thicker than mine than dosent have it, and mines about 100 units later in the serial number range.

I agree with GLPG, I always preferred the parallel in terms of the Jose stuff. I’d start with the three tube setup, you might find that to be sufficient. In my opinion it’s best to work in steps so you learn what your hearing. For example do the depth mod, fire it up and listen. Change one...
