[Boatanchors] OK Smart People: Capacitive Voltage Divider?

[Geoff]

Ive been running full bench buckers for decades for both the ham station and 
repairs. My sources have been hamfests and electronic surplus shops where 
oddball voltages in the 9-14V range cost very little.
At 120V a 20A secondary will handle 2400W if its CCS rated and I run them 
about 75% maximum and usually less.

Besides keeping boatanchor gear happy its amazing how much cooler modern 
gear runs as the regulators arent throwing off so much heat. Since running 
the TS-940's in the 110-113V range I havent had an AVR board failure and 
thats close to 20 years.

The 30's console radios in the upstairs rooms run off their own small 
transformer under the chassis or in a small box that feeds an outlet strip.
