There are also a few resistors and a small electrolytic that change value/go leaky. An hour should be sufficient as that tube ap; /archives//html/Amps/2012-03/msg00295.html (8,170 bytes)

I got this amp in a trade and although it has been converted to two 3CPX800's, he; /archives//html/Amps/2012-03/msg00300.html (9,015 bytes)

Since I dont use my 76PA on WARC (The LK-500ZC does well there) I havent tried it. Carl KM1H __________; /archives//html/Amps/2012-03/msg00304.html (10,844 bytes)

The choke can be resonant around 25MHz and 'pulling a few turns' will undoubtedly raise it. The risk is that it could become a little toasty if you use th; /archives//html/Amps/2012-03/msg00307.html (12,012 bytes)

I worked so hard on my baby I don't want to chance screwing her up, hihi. thanks, Bob K6UJ _______________________________________; /archives//html/Amps/2012-03/msg00312.html (11,772 bytes)

The object is to park the resonance in the middle of the CB garbage pit. Ive no idea where the LK-500 resonan; /archives//html/Amps/2012-03/msg00314.html (13,048 bytes)
