[R-390] RF Tuner Module

[Byron Tatum]

 Meant to mention-   Used a nice vintage CDE 100 pf. 500 vdc silver mica (DM05101J) for C-327. I see an Aerovox film cap 0.033 @ 400 vdc in there, thinking I should replace it. I read in past where someone replaced these Aerovox units in IF module, then made measurements on them afterwards, finding a couple having excessive leakage. Byron W5FH

 Hello-    I am cleaning a fairly nice cond 67 EAC R-390A and have the RF Tuner module all completed. I replaced the mica cap C-327 and the 2 paper bypass caps in calib circuit. I checked all resistors. While I have the module out on bench is there anything else that is a good practice to replace?Thanks,Byron W5FH
