Hello,

I recently purchased the amplifier section out of a portable GE stereogram and am wondering if anyone has any information on the unit.

It has connections for a turntable motor and stylus and has what I understand are the original 5 inch Magnavox speakers.

The unit has 3 pots which the seller believes were volume, tone and balance.

Valves in the amp are 6CA4, 12AX7 and originally a pair of 6GW8s but one has been replaced with a Telefunken ECL86. The original valves are all AWV Super Radiotrons.

I am planning on rehousing it and using it as a stereo amplifier or possibly a guitar practice amp.

Can anyone point me to any information about this GE Stereogram please?


Cheers

Gary

Sounds like the model SA2.

If you unhide your email address via Control Panel, I'll send you the schematic.

Sorry, didn't realise it was hidden. It has been rectified now

A schematic would be much appreciated.

Email addresses are hidden by default as an anti-harvesting measure.

Okay, sent.

Thank you GTC. The schematic has been very helpful.

Still would like to find a picture of a complete GE SA2 if anyone has one.

I think you might actually have a Portable Stereogram Model SA1 chassis.

The amplifier section is the same as the Radio Stereogram Model SA2.

Here are some pictures of various GE models from the front cover of the General Electric Service Data manual. The quality is not so great but it will suffice.

Also some additional service information on the SA1 & SA2.

Thank you very much MonochromeTV. Great to see what the original unit looked like.

The schematics and extra info are very much appreciated.

The SA1 speakers are detachable.
