Power Amp Tech / MT100 Output Transistor Issues
Last post by Dante - April 24, 2024, 03:37:39 PM
Thanks Harley!!

I found a low resolution pic of somebody repairing one, it was folded back and bundled with a zip tie. I couldn't figure out what to connect it to, now I  know. I can also see the dent in my wires where the zip tie used to be.

I see those exact part numbers on mine, now that I've removed that bar from the top. Both are greasy on top, eeeewww...each of these thingys is on a pile of white grease (dialectric?) and there's a square sheet of something under each one, gotta be the mylar

I'll order 10 of each part, shipping will be more than the items :)
Here's the order....look right?

The real question is, how long with this thing last once I replace those? Am I doomed to do this repair over an over ?

I think Gregg would have to have one of these on the bench to trace the circuit and see what's up.

Still, I find this to be an odd issue in the Classic. But I digress, these are old electronics now and components do fail after enough time goes by.

Richard,

   With locking tuners, I only have 1/2 to 3/4 of a wrap around the post. Any more than that and tuning won't return to pitch.

    The staggered tuners help with the string break, as I've had no issues with that since I removed the trees. Most people love the sound of that Strat and want me to play it more, and I agree, it sounds great. It's just so bleeping heavy!

Some people consider ADA rack gear as "vintage" these days.

I still think it's better than most of the junk out there right now.

I have 10 split stacks. If it weren't for those, I would have already bought the amp months ago when you listed it.

Dante,

    Okay, I had to dig out one of my MT 100s to find out. That yellow wire isn't connected to anything. It should be folded back, and zip tied  to the bundle of red wires. That's what I see in mine.

    Yes, those two things under that clamp are the power transistors I believe. They have a mylar sheet under the back of the head. Be sure that is in place when you install the new ones.

     They are: IRF9530 and IRF530 going from left to right

Hey Shibiwan, wow, that's 3 very very nice looking guitars.  I agree the maple top is just gorgeous.  IIRC 1989 was around when the best Charvels were made?  My Anderson is 2 years earlier, 1987 vintage

Nice guitars. Would they be considered vintage by now?

Apparently the best Charvels were the Japanese ones with the Fort Worth, TX neck plate. That was when Charvel/Jackson moved manufacturing to Japan and had their American craftsmen training the Japanese guys in the factory. They probably peaked around 1990-1993, a little after they introduced the recessed trems (~88) and the dinky bodystyle. I feel like it's been downhill ever since, and even more so after Fender bought them up.

@Harley
I will start another thread after this...check out the pix below. One question, where does that yellow wire belong? It's not connected to anything and it looks like it was pulled off something, but I don't see anything loose  :dunno:

Still got the amp and cabs. Might sell it all but it would take a sweet offer. Pulled it all out yesterday to fool around. Still love it so it'll be tough but I'm trying to move away from so much gear.
