Arvin 182TFM Alignment ?
#3

This thing is making me crazy  Icon_redface Icon_redface Icon_redface Icon_redface
It appears I have an intermittent problem. 
1-FM works and has from day one.
2-The AM will come on play for a while then fade out. 
3- I have checked and replaced all resistor out of Tolerance
4- Tubes have been checked and I have had put replacements in no change
5- I have done voltage checks and do not see anything crazy I'm using a digital meter
6- it is not working more than it is, I've poked and prodded looking for cold solder Joints 
7- Had no problem doing an alignment on the am side tone was where it was supposed to be.

I'm beginning to think I might have a capacitor going bad, there are a lot of small dog bone PF capacitors?
Any idea's on where to look??

Thanks Eric
