Matt KM5VI I suspect those capacitors were actually in series and he added up the values printed on them. 73, Victor, 4X6GP Rehovot, Isra; /archives//html/Amps/2020-02/msg00126.html (7,977 bytes)

It is undamaged. Are you referring to this choke for removal? The 811H s; /archives//html/Amps/2020-02/msg00128.html (8,782 bytes)

This is the same either way. The negative side has less voltage to ground. The voltage says 1500 volts, whic; /archives//html/Amps/2020-02/msg00129.html (7,437 bytes)

They use the 270uf in all their amps regardless of how many they use. Thanks, you are correct. So 210 / 4 = 52; /archives//html/Amps/2020-02/msg00131.html (8,194 bytes)
