Outputs 2 (6f6g), 6k7g (if); 6k7g (rf), voltages all 100 volts high.
Possible cause and or possible fix, and or any help i can get.
Thanks as always to those more wise than me.

So post some pics of the top and under the chassis. Let's see what you've got.

TT, do you mean a 38-10? The 39-10RP is a phonograph that was attached to a radio.
RE: 39-10 plate voltages 100 vdc high - PAradiogeek - 08-21-2015
Have you done anything with the radio (like recapping it and checking resistors)? If the answer is no, then don't power it up again until you do.
Good luck.

Its a 37-10 sorry.
RE: 39-10 plate voltages 100 vdc high - klondike98 - 08-23-2015
OK, here's the 37-10 schematic. Have you recapped the set?
RE: 37-10 plate voltages 100 vdc high - ttmiller - 08-24-2015
I have schematic and it has been re-capped. Changes per #269 revisions were made.
RE: 37-10 plate voltages 100 vdc high - Radioroslyn - 08-24-2015
The reason I asked about pics is I wanted see if the power transformer is original to the set among other things.

Here are some instructions for adding pictures. I added the link to the schematic to make it easier for folks to help you.

Will it work if i put pictures in dropbox?
RE: 37-10 plate voltages 100 vdc high - klondike98 - 08-31-2015
Yes, I use dropbox. You put the pictures you want to share in the "public" folder.

I might be doing it wrong but all I'm seeing is thumbnails.

When I click on hhe thumbnail using a chrome browser, it opens to a larger pic for me.
