Peavey EVH5150 problem

[MarkusBass]

Both 5150s here in the shop have aluminum foil.

I'm sure this one had a foil. I could see the signs of a glue and staples (this is visible on my first photo).

The Illinois Caps do tend to puff smoke a bit. The 100s and 47s. Been using F&Ts to replace them.

As I mentioned, I don't see anything wrong with capacitors in this amp.

There is no clean channel. They call it Rhythm because it is not clean. The drawings may reference CLEAN but that is only in comparison to the Ultra and Crunch. The clean channel on this amp is only less dirty than the other channels. Not clean.

I agree; there are RHYTHM and LEAD channels - both distort the signal, only the LEAD has muuuuuuch higher gain.

Bottom shield should affect hum, not hiss.

That's correct; I called it noise but in case of lifting the amp from the floor and turning it, it was a hum. Now, what is left is a hiss.

Peavey doesn;t use foil a lot, they have a conductive black paint they use inside the cabs. Paint won;t peel or tear or snag the chassis.

This must have been one of the earliest models - there was a foil because the staples are left. It requires to be careful when taking the amp out from the enclosure. But in any case you have to turn the amp upside down to remove the rubber feets.

I am happy to accept that these have shielding, I was speaking in the general case for PV amps.


There is no wrong way, but I hate flipping those things over more than I have to. To take the rubber feet off, I usually just hang the end of the amp off the edge of my cart, and reach up under there with the screwdrill, then slide it off the other end, and spin the cart around and do the same on the other end. Pull the rear grille, and usually the front grille, and slide the chassis out. My cart is about 24" square and on wheels, so there is plenty of room for the chassis and head case without having to hold either one.
