90 /w/ 1-47...need help
#4

I appreciate the leads... disconnected the mica cap#14 from the set and isolated #15,16,48, and resistors. All resistors were replaced 2 years back when I first got the set. Rechecked....all were within 10%. I wonder about the mica cap though which is original. I've heard to not worry about those but i'm reading 0.23nF (spec=110 mmf, which screws me up every time, but I think equates to 0.11 nf, so I'm getting 200%*). What impact would this have on the DET.RECT.?
I swapped out the 24s with 24a's last week with no luck. I don't have a 27 on me but rotated their positions previously but didn't detect any differences. Once I get this back together tomorrow I'll try a different 27 for the DET.RECT. tube and remeasure all pins on it. Probably should have tried that first in hindsight.. I'll let u know how things proceed...thanks-
