? A filament-voltmeter for the 3-500Z, in lieu of a grid-current meter,
would have added little to the price. A 1mA DC movement would have
sufficed. A schottkey rectifier costs under $0.50. The most expensive
part would have been the custom AC meter scale. . Typical fil. v. in a
SB-1000 is c. 5.3v.
. In the owner's manual, on page 64 paragraph 12, it says that plate
current max is 550mA. Any comments, Tom?
