[R-390] R390A Audio output transformer T601

[Eric Gauja]

Hi Group,
                   Lost local audio in my R390A last week.  Tracked the problem down to the audio output transformer T601-  only  about 1K ohm primary resistance to ground with the primary disconnected.  I am now temporarily using the line audio channel  , but would like to either replace the original T601 , or substitute with a 10K to 8 ohm suitably small transformer to drive a speaker directly.  I know that the line audio output transformer is identical to the local audio output transformer, and could just interchange these, but since the primaries of both are subjected to B+ voltage,  the line output transformer may well also fail in the not too distant future.   I could also take audio from the diode load , but then the noise limiter circuitry is bypassed, and I have found that in my case , for certain types of noise the noise limiter works very well, so I don’t want to lose it. 
                   Does anybody know of a spare T601 , or other suitable size 10K primary audio output transformer for sale ?

Best Regards,
                        Eric.
