U.S. Peavey Club

Cost me $1500AU back in 1986 and doesnt owe me a thing..still works great..darn thing is a giant beast.

My Peavey MX6 is trashed. Not surprising, since I found it in a dumpster. I'm going to pull any useful parts and possibly toss the rest.

It's probably repairable, but isnt worth the time and parts. One sold on ebay for $50. Not worth it to me.

Someone buggered it up before I got it... started swapping parts in.

Thanks....I'll tell you why I was so curious. My 1987 Patriot is a non-Custom with maple board and non-matching headstock. BUT it has Schaller tuners rather than clovers like the picture shows. A mid-year change maybe?

Same with my non custom, maple board 87. It has the Schaller machines. Well, actually, 3 Schallers and one Hipshot Xtender now.

Hi AudioT..yep cause I bought a '91 Dyna Bass with the written script and the next year or so I noticed the block scripted logos on their Dynas too. The Dynas went through a few changes of headstock machinehead design for the 5ers..mine is a 3+2 design but they changed that also to a 4+1 like the EBMM design..i'm sure kodiakb could enlighten us further.

That 5 string....drool....I want that.
I needed another 5 string bass like a hole in the head, but couldn't pass up this particular 91 Dyna. I love that 4+1 and wanted a SF equipped 5 string. It was really inexpensive, needed a lot of work to get up to snuff (including having to unsolder the pots and crimp them back together to work properly), a new nut, a little ski jump remediation, and had to get a replacement black tuner (hard to find!). All worth it in the end. It was nicely refinished with a green burst, which I really like. This has got to be the very last of the Super Ferrite/4+1 Dyna 5s from 1991, as it looks like the typical 80s SF Dyna 5, but the fingerboard is a flatter radius (I think it measured 12 or 14") vs the 8" radius of the 80s Dynas. They must have been transitioning into the next generation like Giffro has. The string spacing is really tight, but I get around on it OK since spreading out the strings as far as possible without falling off the edge of the fingerboard or extending beyond the magnetic pickup field. It sounds just how I like: Super Ferrites never let me down.

Yep TI i seem to recall reading something along those lines a few days ago..glad you took the careful approach and decided to wait and let it dry to evaluate again from there..I think I read maybe you were considering a small amount of Deoxit D5? Was that you? My memory sucks bad these days but I think it was you and remember you saying you might let it dry..well done..maybe a tiny tiny bit of D5 if it starts to play up..too much of that stuff can rot the actual insulation in pots switches and connections..so little is best loll

Yep. That was me. I prefer not to use any kind of spray, even Deoxit, if I don't have to. Those pots are designed to clean themselves to a degree. But yeah everything worked out fine.

Thankfully! Not sure what I'd do if I had to replace that dual pot since they are made from unobtainium. Probably would have looked for someone that could repair the pot. I think there are a couple people out there that do such things.

I was talking a while back about doing a copy of the Millennium preamp since Peavey no longer makes them. The problem is that darn dual Mid pot and the fact that with those values you cant get them. One solution I have in mind that seems practical is to separate the Mid Sweep and the Cut and Boost into different pots. Then I may be able to use a dual pot on the Treble and Bass or even potentially the Volume and Blend.

Same function just the controls would be different.

Yeah something fried on that, a short somewhere that burned the board on the opposite side where the traces are. Nice thing about a simple one sided circuit board like that is it can be repaired even if the traces are burned in half. Easy fix with a couple Jumper wires. Thing is them you need to figure out what the original problem was that caused it to short in the 1st place. If you can find a replacement board for 50 bucks that's probably the easiest thing to do.

Side note, a friend of mine has an old Dean Markley Signature Series head like Clapton used back in the day except the 60 watt version. Anyway he loaned it to a "friend" and what ever that guy did burned a whole clean thru the board. Since you can't get a replacement main board for those, They didn't make many, he ended up taking to a local amp tech and he was able to repair it and it works as good as it did before.

Like I was saying, a board like that is a fairly easy fix as far as the damage goes.

I could do the work, but it's not worth it for a $50 sale before fees.

That JRC4558D may have been replaced by me 15 years ago (I had started working on it and put it in storage until recently) I made a one-off TS808 clone for a guy back in 2000-01 and wanted to make more. People made such a big deal about that IC on ebay ($10 each) but I found the same thing at Mouser for $0.22 each. So I bought 100. I had a fairly sizable parts stash.

Absolutely it's not worth working on if a replacement is readily available. I just wanted to point out that on many of these type of boards with simple single sided traces, heck doesn't even look like there are barrels for the through hole parts, repair is relatively easy. I know most guys aren't techs here so I would hate to see someone through something very hard to replace for damage of that type.

Most anything can be fixed, just depends on conviction and how deep your pockets are.

I wish I knew more about electronics and being able to fix my own gear if something blows..reading your posts AT and TI about your electronic adventures makes me feel like i'm on the outside looking in..envious loll..after all this little fella only looks like an electronic spider to me lolll
