I have a Bozak transformer that I would like to see a full schematic on. Pretty much has to be a mic input transformer, Altec and Bozak routinely used octal base transformers for this.The number is CMK-481Apparently made by Kenyon, the Kenyon # is: S-509023 or possibly S-509028-can't tell. Found some really old PDF copies of Kenyon catalogs but nothing like this in them. If there are Bozak schematics around I can't find them.This I do know:pins 4-6 low, pins 7-8 high. pin 8 is also case ground (if there is a faraday shield, might be there too, one thing I would like to know). pins 4 and 7 are in polarity with each other.Any ideas?
A friend sent me this help request last week, can anyone help him out?Thanks,Gene
Sounds like he's already figured it out. Not sure what the question is, unless it's that he wants an unobtainium blueprint on a custom part.
