I have a lead on what is described as a 1995 2ch with small logo
I thought small logo was before 1995 :confused:
After much googling, it seems this could be anything from a C>G? Does that sound right until I can get more info like serial #?

Also, this is in the description:
  • The 2nd channel(distortion) works great with NO PROBLEMS, but the 1st channel has a small problem. After powered on for about 30mins, the power cuts and sounds like it's 5 watts. This affects ONLY the clean channel.

So with this limited info, what is the worst case scenario for repairs? It mentions all new tubes, so I assume the new tubes did not fix this clean issue. If it is a Transformer issue, you would think it would effect both channels (?) If it needs new transformers, I think that loses interest for me. I also imagine that at least the caps need replacement...I'm trying to determine if I should make a low ball bid
 
I'm pretty sure it's a G, maybe an F. I'd rely more on the serial # than the small logo, since there was a period of transition as far as the aesthetics.

As far as the 'clean' channel issue, I'd make sure I get it for the right price, since you are essentially taking a risk.

But yeah, let us know the serial # and how much he wants, and that would help tremendously with whether or not it would be a good buy.

I was looking at that one too. Don't need it, not to buy, just curious what the issue is.
Good luck.
 
No idea what the issue could be.

Regard the rev: does it have a serial or parallel loop? If parallel, it's a Rev G. If it's a serial loop, probably a Rev F but still could be a Rev G.
 
listed at $650
waiting on more information...
 
Keep in mind the 'magic' channel on that amp is the first channel, Orange Hi Gain. . .not the Red Overdrive channel.

You might be able to clone the Orange to the Red Channel, but it still isn't quite the same.

The problem is most likely one of the many optoisolators in that amp is going bad. It is a common problem on those after they get some age on them. Mesa labels them LDRs on their schematics if i remember right, but there is a ton of them that switch alot of stuff inside that amp. The part is not going to be expensive , but the troubleshooting could be.
If you can find a good tech you could be scoring a GREAT deal on a cool amp.
 
ok, here's more info, could be a cool piece (?)

the serial number is under 5000. I've taken it to a couple amp techs and they couldn't figure it out. It's not the tubes though. Power cable is hard wired. I believe there's a selector on the back of it that you can choose how you want the effects loop.

It's most likely those optoisolators...there are a lot of them in there. You could just replace all of them not that they would all be bad. But there is a fair amount of disassembly to get to them. A good tech should be able to find it fairly easy.
 
You could call Mesa and tell them you have a line on a 2 ch Recto you can get for cheap that has bad LDRs and get an estimate to repair them, factor in shipping, then decide if the amp is still a good deal or use the information as ammo to negotiate the price downward.

Considering there's a Rev G Recto in a shop downtown hat I can buy for $838 USD right now I'd offer $200 for that amp. It's broken and the total cost to purchase and repair would have to be well below $838 for me to even bother taking the risk and putting the effort into it. The $650 asking price puts a $200 repair at $850...

Chances are the guy would fuck me off over the lowball offer, and in fairness he'd be right to because I'm sure that someone is stupid enough to buy that amp 'as is', but it wouldn't be me.

IMO...YMMV, and all that jazz.
 
A '95 is hands down a Rev G. I would not pay $650 for a Rev G with issues. You can find them off an on CL ads for $700 to $800 that work like new if your keep your eyes open. Would have to be $300 to $400 tops to be worth the effort. Even then, I'd probably pass on it.
 
Thanks for the replies...looks like I will pass
