I usually sail pretty close to the wind. I work on having 1 spare
capacitor worth of headroom in a bank. For example, if the dc voltage
is 4500V, then I would use 11 x 450VW capacitors in the bank. Never
had a cap go bang on me by using that crude formula.
Denny used 7 caps when everyone else used 8. I just had to recap an
LK-500 because of a bad cap. He always found a way to save a penny. The
worst
blunder I think he made was not only didn't he have a grid trip on the
DTR-2000L, he didn't even have a metering scheme for the grid. Then when he
DID use some sort of grid trip and Hi plate current trip safety measure, it
was on the LK-500ZC with 3-500's. Who needs that?
Yet the DTR-2000L is a highly sought after amplifier, and a nice one will
bring over $1500.00. Go figure. I won't go into not using a filament choke
and using chassis return on the filament supply and a blower that might
handle a 6146.
