A single site mother lode of Tube information, many links:
http://www.tubebooks.org/tube_data.htm
What it does not explain is how/why there are companies that are able to sell
200 watt TUBE audio amps (using 3-400Z, looks like) for $18,000.
Nor does it give out that company's customer list. Somewhere there is a photo
of a "monoblock" tube amp with a large Transmitting tube in prominent position
for $18,000, two required for stereo. If you want to satisfy real needs for
QRO HF amps, you can fund your habit simply by building a "high end"
audio tube amp or two, each year.
