16 B X 2 Shadowmeters
#7

(09-29-2014, 03:08 PM)PAradiogeek Wrote:  You had mentioned that the "...AVC voltage seems to be tracking along with tuning" so I assumed the problem was with the adjustment of the meter itself.  What is the voltage difference on the AVC line between a strong station and no station?

My next guess would a weak tube somewhere between the RF and 2nd IF tubes.  Have the tubes been tested?  Even if you have and they test OK, it may be worth swapping out a few tubes in there to see if you get any better response out of the meter.

What I actually meant was that I could watch the AVC voltage go up and down as I tuned on and off a strong station. I am going to go back out to the shop now and measure again. I addressed what I thought the voltage might be in my response to Mondial in the previous post. It sounds like after reading his post that the amount I was reading would not be sufficient to move the meter.

Thanks,  Frank
