Picked up this VOM Tape Player off craigslist for 10 dollars. It is so cool. It is a Model 700. Looks really snazzy. I have not opened it up yet. Sounds great with a guitar plugged in clean to just breaking up. Cranked wide open is not good, too buzzy. I know just enough about repairs/electronics to be slightly dangerous. I know it needs a new power cord as the old one is crumbling. It came with everything, manual, two microphones (one works fine, one does not). Tubes are 5879, 12AX7, 2 6v6 and 5Y3. I have tried a tape, and it worked but not correctly (dragging and low output) I really don't need the tape player part anyway and may remove it. If I did, I could put a larger speaker in the lid. It has 2 speakers a 5x7 woofer and a 31/2" tweeter both alnicos. It has two inputs...microphone and magnetic and two out puts. Speaker one disconects the internal speaker (not tried yet) and speaker two is in addition to the internal speaker (not tried yet). I am open to suggestions.

I believe the date of manufacture is 1954. Apparently this was Voice of Music's first tape player. Would not the tube config make it similar to an early champ?

Not really sure if this is a good fit but worth a shot.

I have picked up a couple of these, one was a VOM, and the other was relabeled Phillips. Both were single ended with 6v6 power tubes and with several 12ax7 tubes, along with 5y3 tubes. Both have really nice transformers as well. They should make great champ/ Princeton type amps.
Yours has two 6v6's? Is it a push pull amp or a stereo single ended?
It should make a fun project either way.

Check one of those 6v6's, it may actually be a 6sn7.

I have too many projects going on. I have put this up for sale under classifieds. If it does not sale, I will save it for a future project. This is a great amp with 2 6v6's. I opened it up and took some more pictures. I wish I had gone ahead and opened the bottom and took a shot of the guts. The 2 power tubes are Tung-sol. At least one of the other large tubes is a sylvania.
Has adjustment screws for Hum Balance, Bass Boost, and Distortion.

Interesting, it uses a single-ended 6V6 for the output, and the other 6V6 for... something else. I bet with a different OT, these guts could make a decent 5E3. If the B+ from this PT is low, you could use other rectifiers to bring it up.

I noted one interesting feature. In the last picture, you can see the transformer set at an angle and not only that, it is slotted in such a way as that it can be rotated. I assume to reduce noice/hum.

Used to drive the erase and record heads.

On other models they used the 6SN7 or 12AU7 tubes in that spot.
It was that way on the two 700 models I had. They have great looking iron though.

I believe this is a 1954 model from what I kind find.
