ok, this version of the Pye compressor with two output transformers is causing problems,
a new xfmr DIY style was wound and wired into the OPT slot which requires an FB wind, so we went with a 2.2K:600 with a 110 turn FB which works out to about 8.8 to 1 or something,
but the darn thing oscillates, so we are thinking either the FB ratio is two low or there is a problem with the schemo,
a real xfmr was measured with a much higher DCR than we wound, but we thought that this was an error, so maybe the orig xfmr has a lot of turns on the FB wind which does not make sense,
any thoughts? thanks!
