A gassy Thankgiving with a 37-650
#1

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
