Hi all,
Hopefully you took the title tongue and cheek. I like to rotate my consoles every 6-9 months to give them each some playing time and keep them active. My 37-650, has been out of service since May- June sometime. On Thanksgiving morning I went to fire it up and got no sound, nothing, just dial indicator lamp. This evening I decided to dig into it, and what happens is the rectifier (5Y4G) starts to glow a beautiful purple, I hear some audio for about 5 to 10 seconds, then some brighter purple, a little arcing inside the tube , then silence. Am I to assume I need a new recifier tube? The radio was rebuilt by me, about a year ago and was my daily driver for quite a while, and worked well 6 months ago. Just trying to save time in unnecessary troubleshouting as nothing should have been disturbed while it was idle.
Thanks, Don
