Hi all, I've been working on improvements to Capt Lee's Product Detector mod to the R-390A. One is using a 6BY6 in place of the 6BE6. Another is using a relay to switch the audio for AM or SSB reception (thank you Jacques Fortin and W7DI (Eugene Hubbell)). Both are done and functioning very well and documented on our website (r-390a.net) here: Improving Capt Lee Product Detector (r-390a.net) <https://www.r-390a.net/Improving%20Lee%20Prod%20Det%20and%20SSB%20AGC.pdf>
