Earth Producer 440 Module

Posted in blog. Maybe this is area I may get an answer.
Serial #16139 - anyone have idea when it was built?

Two cylinders inside cabinet, look like tube enclosures but can't be, wired directly to top of cylinder. One person said they are old high volt transisters. Another (more knowledgable) said they are silicone tubes. Anyone know?

I posted three pics: before, after and the back.

Not quite finished cleaning up yet, but close. Took three nights just to polish the 16 metal knobs, did it by hand.

Handle chrome is a little corroded and one of the cord storage brackets is broken in back. Also I am missing the foot switch.

Anyone have a clue where to get parts?
Can old Peavy parts work? Amp looks very similiar to Peavey Musicman on e-bay.

Would also like to get a schematic if anyone has one.

This thing is awesome sounding, and the reverb! Never heard anything that deep or strong. $45.00 including a cabinet with 2-tweeters and a Magnatone 15" marked '67'.

Maybe I finally found myself a real deal !!!!

The two cylinders

Hello arm55555, maybe too late to reply but the two cylinders are capacitors. These are part of the power supply and are needed to produce a steady direct current. At the backplate the eight power transistors are visible. Please change the poor wiring at the back (supply voltage)- => deadly :-} .

Does the clean signal blend

Does the clean signal blend in underneath the distortion/fuzz signal on yours?

Blend signal

Either jack I plug into it seems to do it but I don't mind it much.
Jacks are supposed to be far left high gain-next normal according to Peavey manual. Same with the clean channel.

All distort and just a little 'verb, maybe three, and I get the bottle sound I like. To much verb and it seems to kill the clean-ness of the other effects, but I luv the reverb alone. My cab came with head but may not be original, 15" Magnatone (marked '67) 4"x15" horn and two 3" tweeters.

Does everything I want and more. I am a really happy Earth owner.
If the footswitch I ordered works (can't try the plug until I get it) there is no way that I would part with this setup.

signal blend

Fuzz, distort, tremelo & reverb all seem to work a little different than other amps. Distort and fuzz both seem to blend.
I found an amp guru in my area (if 55 miles away is area) and he is familiar with Earth and is going to check mine out.
I will ask him what he knows about this when we talk.
Will let ya know soon

I have a couple of Earth 1961 112 Revivals

I have a couple of Earth 1961 112 Revivals. They were also clones but of a different amp.

I do have an old Peavey Standard 400 head. It is a slightly different layout on the front but looks similar. Not sure what the cylindars are but I would look for a Peavey schematic.

It is likely an exact clone

It is likely an exact clone of the Musicman. If you read through the posts here you can find the history of Earth. They produced direct copies of Peavey amps in the early 70's. Company and support are long gone. Just a few of us left with working examples.

So, yes, you have a rare find. Welcome to the club.
