Default Vintage GE Tube Amp

I just picked up this GE amp and I have a few questions. Can anyone identify this model? I had no luck finding anything else that looks like it. The seller told me that it is a 5 - 10 watt amp, not sure if he meant wpc or total. What kind of speakers would be a good match for this? I plan on using a turntable with it. Would I need to use a pre-amp or would I be fine running a turntable directly into it?

I have no info on the amp, but to answer your other question... Looking at the number of valves in use, most likely the phono input is treated very similarly to the others in terms of levels (maybe some equalisation changes) and so the phono input would be designed to take a signal from a ceramic cartridge rather than a moving magnet cartridge as would be the case with a modern phono input for a turntable. If you wish to use a moving magent (or moving coil) cartridge then an external phono pre-amp with RIAA equalisation would be needed.

Looks like a stereo SE model. I strongly suspect the tube complement is a 12AX7, 2X 6BQ5, and a 5Y3. O/P will be approx. 5 WPC. 12E1 is correct about no RIAA preamp section being present.

The orange cardboard electrolytic capacitor should be replaced, along with any other 'lytics that can be found.

It's not "ancient". Notice the printed circuit boards.

The painted wood instead of metal suggests a low end model. I wonder what attached to the hinges.

The chassis with its oval speaker cutout, unlabeled controls and exposed parts is certainly from somewhere else, maybe the lid of a "record player" or something like that. And those fancy output connectors! It was somebody's love child, so give it a loving home. (And for safety's sake, cover it up some!)

All good fortune,
Chris

Agreed, chassis is a craft-brew... circuit is common to a number of GE radio and console amps, SE 7189 or 6AQ5, I'd give a link to a schematic but the techpreservation site is down...

Thanks for the info. I'm still kind of confused about what kind of speakers would work well with this amp. Would any 8 ohm speakers be fine? I would want high efficiency speakers right? Any suggestions?

Would speakers rated at 89 db per watt efficiency work well with this amp?
