[Johnson] Valiant Pi Net Caps

[Lawrence Steeno]

I have 2 Valiant transmitters here with shorted, or leaky caps in the PI network. These are in the coupling circuit. The 300 mmf cap is the worst and the octagon 3 section not much better.
I have tried ceramic 2KV and also snubber caps all of which do not last very long. Does anyone have any suggestions as to where I can find the 4 different caps to replace these in at least 2 units and there is another one at another location with strange loading at times. Any suggestions sure will be appreciated. 
Thanks
