I had one R-390 (non A) that I restored for a friend. The RF deck slugs were packed with grease in all of the bores. There was some pistoning action going on there trying to tune across the band.
It ended up being more trouble than it was worth; The solvents that I needed to use to remove the white lithium grease caused problems with the enamel on some of the windings. Even the racks of slugs were deteriorating from the saturation and the Q had changed so it necessitated an entire retune of things normally left alone. What started as a favor that should have taken maybe a day for a tuneup and testing ended up taking more than two weeks. They then started to complain about how long it was taking and I was explaining that they weren't paying me for my time. The friendship suffered for that; I don't restore radios for other people any more. *Ms. Tisha Hayes, AA4HA* "Humans with AI; It'll be like Plyfoxians with a Slurb Hail Soyka!" ______________________________________________________________ R-390 mailing list Home: http://mailman.qth.net/mailman/listinfo/r-390 Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
