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

Let me know if the new 5Y4G corrects the problem.  Similar circumstances happened to me.  I repaired the chassis about 4 months back and I just finished the cabinet.  Reinstalled the chassis and now it draws too much current. The 5Y4G has some loose gray flecks floating around but checks good on the tube testor. Has anyone experienced the same problem?  I pulled the rectifier and it still draws too much current. I'll double check the transformers winding
