I recently did someone a big favor and when it was done, the said, come on in here , I have something you can have, and I would like it to go to a good home so..they gave me a Altec 353A stereo power amplifier pre amplifer with a light bronze/brown metallic front panel. I looked in the rear and there are 4 tubes and they are power output tubes 6L6. It looks like new and appears to be totally functional....I apoligize for this not being a speaker altec question, but is there anyone who has any info on this rare piece of altec history? It must weigh 50 lbs and must have some outragous transformers inside. I am not at a spot in time where i can open it up yet, so hoped someone could help me with any information? Thanks......
