That will work.Robb here is that part I think. The numbers on it are as seen on the pic below.

This is the part number I see. I hope this is what you are speaking of. I am no amp expert by any means either!! Again, hope I got the correct part for you.
Used the mfj259 antenna analyzer on the amps input. Read that the SWR is 2.6:1.10w drive should make about 200w output with a pair of 454's on 13.8v,
i have come across amps that have high vswr and attenuate your power in bypass mode, cp163's do it,
sometimes a trimmer cap from the bypass side of the relay to ground will tune out most of the mismatch.
Have the board out again and testing parts for failure. No luck so far. Not giving up - tho. This would be easier if I had a schematic for it; but cannot find one on the net anywhere.robb,
have you looked for burnt parts that could be causing the bypass missmatch? sometimes amps have a cap,
not sure if you can get at the relay bypass to tack small caps on in that amp without major messing, its worth a try if you can and you cant see anything else connected to the line that could be damaged,
I thought I read somewhere to use the analizer on an amp input but could not find it again. Is this procedure as easy as it sounds? Thanks!Used the
Used the mfj259 antenna analyzer on the amps input. Read that the SWR is 2.6:1.
So, it is in need of tuning.
Problem is, I don't have any variable compression caps - or any other variable caps - to determine what value is needed to bring the input SWR back into proper working order.
Put a 2N2222 in the receive amp, and it works again. Bought it at Radio Shack with some 2N3904's in a 15 piece variety pack for $3.50. So, one problem down and one to go.
Keep you posted . . . thanks!
Mind you, I'm no electrical engineer nor do I have a vast electronic background or knowledge base. I'd read someone using the analyzer to measure the capacitive and inductive reactance through the unenergized port. Although the output combiner and cap are doing something completely different than matching, I think it would be better explained by someone else that can give it the details your question deserves.I thought I read somewhere to use the analizer on an amp input but could not find it again.
