  Sounds like Sarser's Musician's Amplifier to me too.

  I've got one but w/ 350B's vs. 807's.

  All Peerless iron including the S-265-Q.

    Hi -
    
    Just noticed this -
    
    I wonder how many of us have these & what have all done to update / replace parts to make the amps more reliable / preserve & protect the wonderful transformers, and any improvements / tweaks?
    
    I have several I have collected over the years...

  Stancor had a 807/6sn7 schematic that was included in their transformer brochures about 47-51 and they even offered "kits" for people that didn't want to scrounge up all the parts themselves.

  The amplifier could well be the Musician's Amplifier circuit published by Sarser and Sprinkle in Audio Engineering. At least it specifies the same tubes and OPT. As you surmised, it is a variation of the Williamson circuit using 807 tubes since KT66 tubes were not available at the time. A reprint of that and other circuits is available from the AudioXpress website in "Audio Anthology Vol. 1, When Audio Was Young.

    Thanks for the info. Do you know the approximate date as I have access to the Audio Eng. back issues? Is this the same David Sarser who used to sell Ampex in NYC area?
    He is still alive (80 something) and I have his email somewhere. We have spoken via email about some Ampex items as I'm a member of that list.

      According to my Audio Anthology it was published in Nov. 1949. Beyond the name of the author I have no other info, sorry. I forgot to add I have no idea about the preamp, either.
