Lot's of good info to check. I applied some voltage as I outlined above but did not go full voltage. I had about 3v on the filaments they all read the same and had about 100v on the speaker also I got a hum out of the speaker. But a thought came to me I have 5 01A's and one 171. The 171 is supposed to be in the last stage audio how can I determine that? Would the 171 be hooked up to the speaker? If you look at the under side of the chassis you will notice that one socket on the end is different from the others it is spring loaded why?
