In fact RCA used the 6DQ5 with my new FBX thru CTC12 then switched to the 6JE6 in the CTC15 with the same FBX. If this doesn't calm the ultor out of the mid 40KVs, I'm at a loss.
Thanks a lot......Tom

Your welcome Tom. I just looked at the RCA manual, and the specs for the tubes 6DQ5 and 6JE6 for practical applications are identical, only a few minor differences, and the 6DQ5 looks like an excellent sub for the 6CB5, but for the connections at the bases. Interesting that the pin outs are different, perhaps to prevent quick swapping, protect patents, or to generate service revenue when uninformed techs subbed one for the other lol.
Let us know how the swap works. Hope it all comes together the way you want.
