40-165 Alignment adapter
#3

(12-31-2014, 12:47 PM)keith49vj3 Wrote:  All, I need lots of advice on numerous fronts.  I’ve got several threads going on the radio, one is showing off the cabinet in the antique radio discussion forum Zephyr , another is asking whether I can plug it in without the speaker http://philcoradio.com/phorum/showthread.php?tid=11244  and the third  is on the antenna http://philcoradio.com/phorum/showthread.php?tid=10884 .  Now I’m moving onto what I hope is my last problem  and since it’s on a different topic I thought I’d start a new thread.  The radio is a Philco 40-165 installed in a Zephyr Radiobar cabinet.  Based on capacitors of various vintages I suspect I’m working on the third rebuild.  So far I have replaced all of the paper and electrolytic capacitors and all of the out of spec resistors.  Much but not all of the rubber wiring has been replaced.  When I power it up I could hear a loud ticking noise through the speaker.  While trying to locate this noise I noticed that the previous repairman had opened up the second IF transformer  based on the observation that it was loose and was missing the nut at the top of the can. By adjusting the mica capacitors on this transformer I was able to get the ticking noise to go away but now I need to align this set.  The manual says to use an alignment socket adapter.  I suspect I don’t need this if I attach my VTVM to the correct pins under the chassis but I have no idea what pins to use. So my  question is how to connect my VTVM when I don’t have the alignment adapter?
I told all my friends that I’d have this project finished by the end of the year and I only have 14 hours left.
Thanks in advance,
Keith

I a pretty much always align via AVC on all my radios, including my 40-180 which also called for a tube adaptor. I believe on your radio that would be the intersection of R6, C7, R38, and the 1st IF. But I'm not 100% sure on that. 

Either way, I believe that adaptor just taps pin 6 of the tube it's inserted to. So maybe my guess above about the AVC is off slightly.
