I’ve solid stated the power supplies and beefed up the electrolytics in my
Ranger I and it’s working fine but of course the B+ voltages are now too
high. (Around 800 on the high B+ and 600 on the low.) I’ve been using a
variac set at around 90 volts on the mains to drop them down to a safe
range.  Anybody have a more elegant solution to drop the B+?
