I'm repairing/aligning a R-391 for a friend. Every single RF deck slug tuning screw is solidly stuck. I think it is a galvanic response between the brass and steel.
Does anyone have tips to free the slugs? They won't budge using a moderate amount of force. I've used PB Blaster and heat to no avail. I've repaired at least one hundred 389/390/390a/391 over the years but this is the first one I've encountered with every slug stuck. Thanks in advance for any ideas. 73, Mack W4AX https://www.qrz.com/db/w4ax ______________________________________________________________ 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
