Careful Neal, that only means you can afford to pay more for the amp!

King Solomon sez: saw it in half and send you each a piece.

I buy lots of amps from '84 to '92. Dust means nothing. so does case grime. What I look for is corrosion on the transformers, connectors, and reverb tank if it has one. It's a bad sign. To make it reliable, you have to clean lots of stuff anyway.

That amp is another amp like lots of other amps. I like the bias tap and it even has a choke. You could make it very Fender or Marshall if you don't like it as-is. With four triodes, you can build most of the classic preamps. Get it working stock first, so that you can test any mods as you do them, and know that any problems are your fault.

So the question is whether you want to get in there and bring it up to snuff. It's a bit of work though, and you'll need to buy and install caps and probably most of the tubes. The pots might clean up well, or they may not.

I've paid $250 to $450 shipped for grey fuzzy Carvin X100Bs (and they still make them down San Diego way, though the reverb tank has gone solid-state), but they've got a reverb tank, GEQ, +/- 15V supplies, channel switching, etc, and they're usually combos. It's a party in there. "As is - not working", I'd easily go $100 + shipping (for an X100B, not your Mitchell).

Vintage doesn't mean old. It means old and popular. It's OK to mod unloved older amps, especially if you document the mods and stick them inside the amp (where there's no fire danger) along with the original schematic. It's amazing what percentage of 100W amps from that era have received "improvements", and Carvin rework due to design revisions looks like it was performed by monkeys, so there can be mysteries about what's a mod and what isn't. Sometimes you get cool changes like a power line filter or handles.

If you look at the cost for a chassis, power entry module, sockets, caps, transformers, choke, pots, knobs, covering, little rubber feet, wire, ... Starting from scratch is pricey.

I find that amps with covers are almost always in great shape. It makes a big difference.

Recent amps can provide more challenges, with complex dissassembly, surface-mount components, lead-free solder, lots of boards, solid-state effects modules, etc.

I don't see any corrosion externally, aged metal with some staining yes, but internally I guess will be the real concern. The only thing visible is the tube sockets, tubes, some metal cap looking things (with springs in them?) and a HUGE power supply transformer which all look good to me. The transformer has very slight rusting on it but its so slight its a non issue I believe. I think a little brushing with a stiff bristle brush will easily remove that if appearance matters. IMO this thing is only good as a platform for a rebuild project, that's what I would do with it anyway, lol. I would be interested in hearing it working again though.

Today I will break out the warm water + dish soap and do a little careful sponge cleaning of the vinyl. Also, going to pull the board out today as well and have a look around, clean up any webs/dust etc. I was a practicing electronics tech (actually a QA technician) back then so I "think" I have already opened this once before to redo the solder joints, but I could be wrong. I love fixing bad soldering, so that's why I say that. Once I get it presentable I will take some close up "macro" shots of the entire thing head to toe. My zip is 87059 if you want to figure out what shipping could cost. You probably have a better idea of its weight and dimensions than I currently do.

Thanks for the info. I will get this posted in the For Sale forum later today.

Torn Cone, I just sent you some pics of this thing in a private message to see if this thing is worth cleaning up and selling in your opinion. I may just post what I have in the way of pics and the video and see if anyone wants it as-is, but would like your opinion first. Thanks

im going to retract my offer, this thread is so far off of xtians OP

start a new thread, unless you are discussing xtians build, kind of rude

Ok, if I only knew what you were talking about, lol. I thought this thread was specifically about the Mitchell PRO 100, as the title suggests?

OH crap, on second thought I just realized what your talking about, the OP is xtians and he was discussing something else not related to fixing up and selling Mitchell. Gotcha! Please forgive me as I just thought it was a Mitchell thread specifically for this model.

I will create my own thread. Thanks man!

[eniam rognab]

no worries, it happens, just a friendly reminder

[xtian]

This is certainly the correct place if you're interested in discussing the Mitchell PRO 100. Photos, especially, very cool. There are very few of these to be seen on the intertubes, and I have very much enjoyed modding mine.

But if you just want to sell, post in the For Sale section.

If you twist those metal cap looking things a little, it should unlatch them from their bases to reveal, taaa-daaaa, your preamp tubes.

Yeah, I know. That is why there is a spring in there to keep the tube from falling out with all the shredding, haha. I just didn't want to touch them, but on second thought, yesterday I noticed one of the tips of the tube is not exactly centered, which makes me think it may be shattered in there. I guess I will open it up and see.

Pictures are going to change since I "think" I will have time today to try and clean it up a bit. But here is what I have now, both a video and stills. Looks like this may be a 1979 or 80's model or at least one date code says Feb 28 1979.
