Philco 42-1012 Alignment
#11

Ok, Thanks for the reply..

PS AM plays perfect. Right on Frequency and lots of stations.

I did replace all caps. Minus the Mica ones except one Number 27 a 185 uuf was replaced because it was inline with the SW osc coil. Only resistors I replaced were 3 that was for the 2 7C5 output tubes. One tube was running a lot hotter than the other. Now they both are same temp. and volume increased..

No tube shields present all loctal tubes.

Signal Generator is a HP 8657A Calibrated. Freq counter is a HP 5385A calibrated. I use a output meter TS-585 C/u or a HP 400F AC voltmeter.

PS the inside of this is very crowded. Really hard to get at parts. That being said I will try to check all resistors. Whats a good % out of tolerance. 20 % or less. here is a picture of what the inside looks like..

I used the alignment procedure. SW is the last step before FM alignment. its step # 5.

Thanks
Skip..
