Sorry about the multiple posts - I feel like a kid at Christmas with a new toy with this 531 
. Had more time to tinker with it. Simple oversight on my part for the lack of reception. While there was a coil of wire on the antenna lug, apparently spreading it out (or simply connecting the LOC lug to the ANTENNA lug) was that problem. Found that when I was cheking plate voltages, the meter lead made a station pop in. Now that this is resolved, I have one additional problem with the set and a recapping question.
When the unit is first powered up and a station tuned in, I get good volume output for about a minute or two and then it slowly fades to very low volume. Turning the set off and back on after less than a minute will again result in a good output until it again fades.
Question on recapping this unit. Should I just be concerned with recapping the electrolytics in main 'condenser' or in your experience should other caps be replaced. Also with the electrolytics - can I simply install new caps on the underside of the chassis and leave the existing condenser wires in place?
Thanks again!
