Re: Volatge rating of caps in VTTC

I'd have to differ here.... Your caps will probably see 600VDC with a
superimposed RF sinewave of at least 500V, if not more, depending on the
placement of the caps in the circuit. 5kV might be conservative, but 1kV
would be pretty optimistic. Surplus 3-4 kV mica small value bypass caps are
readily available with a bit of scrounging in the under $3 range.
