Wow. I have a Tek 575 transistor curve tracer, in excellent condition
except for a sluggish cooling fan, and its voltages go up high enough for
many tube tests (200 V). It does not have a filament supply. How much
could I get for it?
For that matter, maybe I should build a microprocessor-based tube analyzer.
How much would such a thing sell for?
