?? I went to Digikey and bought 5 of all of the caps in the LPF area just to be sure. Yes I've never found a bad cap either!? Maybe I'll screw around with prototyping some toroids and these caps, and then measure the prototype filter with my tracking generator. The installed caps all measure the correct value according to my LCR meter.? I also rewound L1 - L4 and then adjusted the turns using my LCR meter to make sure all the inductance values meet the values given in your tables. I also measured the PA output pp and can see 32Vpp which is a little less than what is shown in the troubleshooting manual, but not enough, I? believe, to get the output power down to the 0.5W that I've been getting. I've seen your 3 links above and they are very instructive.
?? My main problem is that no matter which coil I adjust, I never see any output change, so I don't know whether to add or subtract turns. On L1 I took out 2 turns and got no response, so I added in 4 turns to go in the other direction and still got no change to the power.? Now that I know the inductance values are pretty accurate, I'll probably go back and try the compressing and stretching the turns once again.
