To prove Rich's observation about caps blowin up when the eq
resistor opens.... I'm proposing a test. Using a variac.... dial
it up so +400 vdc appears across the string of 8 x caps [50 v per
cap] THEN open one resistor [the one at the cold end]... then
watch the V go up on the cap with the open resistor.... and watch the
other 7 x cap's Voltage.... drop.
This way... the cap with the open resistor should hit +400 vdc....
and no big bangs. IF this is the case... how come u never see it
mentioned in the arrl handbook/orr's books ? Should be in big
black print on page 1 of the HV pwr supply section..... or what's
left of it. The league loves publishing books.... how about a super
thick hardcover one... just for linears ? .... done right this
time.... nah.. they would screw it up. YC-156... nah... u need one
of those $7500.00 Acoms.
Later... Jim VE7RF
