Greetings All,

I have the (mis)fortune of owning 4 AEA PK232  modems, all now unworking.  I use them to convert 45 baud baudot into ASCII for my 1980's terminal.

All four have similar symptoms--they communicate ok to the ASCII terminal but are no longer able to read or process the audio tones from ITTTY. 

Just wondering if any member has experience servicing these devils. Perhaps there is a common mode of failure somewhere in the audio chain. Or am I looking at replacing all the electrolytics? Thanks for any advice.
