[Boatanchors] LINE VOLTAGE, FILAMENT VOLTAGE and SANITY

[Pete Lancashire]

Agree and BB transformers can usually be found for close to free, if
you are not in a rush. I got a 5 KVA (41A at 120V) for $25 that was from
a building being demolished in the city I live in. Bigger then I
wanted but the price did it, it even came with about 20 feet of THHN,
watertight condut whips, etc. and a lot of sheetrock dust. There is a
1.5 KVA one on Craigslist for $35 in same city.

Just keep looking and ask around,

> Why all the discussion about filament voltage and monitoring the line?  The line voltages across North America are probably 12-15 volts higher than they were when our equipment was designed and built in the 50s.  Install a line bucker of 10V......just do it!  Don’t worry about the filament voltage-anything within a half volt of 6.3 won’t adversely affect the operation of your equipment.  With a line bucker everything runs cooler, and IMHO that is the REAL reason you would want to use one.  Your power transformer will be much happier and tubes meant to work at 250V will not be struggling at close to 300V with high line voltage.
