I have the amp listed in the subject. I noticed today, that the input tune was high, this is a new to me amp. I know the coax is fine and antenna, I've been thru that. This amp has two pills, not FETs inside, I noticed on top of the transformer the silver mica cap was burnt and it measured about 230pf. I removed it and I could not really read the writing, but it looked like 1000pf at 500 volts. I replaced it with something close and the input tuning came down to about 1.5, which was an improvement on the 2.0 swr I did have. The other cap on the output transformer I could clearly read at 750pf. I cannot find any schematics on it, I was hoping maybe someone had some knowledge.

My only other recourse is to buy an assortment and play with different ones.
