Hello Vance,
I remember that the OA2 tube is a voltage regulator tube. Perhaps power supply voltages would be the first thing to look at.
If you are looking for someone professional to repair it, the following web page should be helpful. (This site should be helpful to writers of other recent posts who are looking for parts) http://www.wb4hfn.com/DrakeParts.htm
This is a great general Drake site, so after you find what you need, check out the other pages by hitting the Drake Home Page link. Kudos to Ron WB4HFN !!!!!!

Hello,I have a Drake TR-4 that I think I have ruined.Some years ago, a friend at work gave me a TR-4 he bought brand new back in 77. However, he had stored it in his storage room and a mouse had built a nest in it.Well I cleaned it up and it actually worked !It would get kinda quirky sometimes. I tried to nutralize the finals one time and that's when my troubles began. It quickly went into self ocillation and burned a 470 ohm resistor going to T10. It had no audio or would not key up the relays. OA2 doesn't seem to light up anymore either.I gave the radio to another friend who said he knew a guy who could fix it. Well, I got the radio back the other day. My friend never got it fixed.I would really hate to trash this radio, it worked pretty good when it was working.Anybody got any ideas where to start ?ThanksVanceN5HNY
