I checked the balun, subbed tuners and the whole bit before finally realizing it was the god dang matching transformer. Glad you found it quickly without unnecessary cap replacement because I was going to suggest it as soon as I first started to read this thread!

Me to Doug, been bitten by a bad matching transformer.

one of those automatic 1st things, so auto you can forget to mention to others.
I bet the OP will never forget to check next time.
