[Boatanchors] FS For: B&K Model 500 Dyna-Quick Mutual Transconductance tube tester

[Charlie Hugg]

FS For: B&K Model 500 Dyna-Quick Mutual Transconductance tube tester with
510 expansion module. This tube tester works great. I compared readings with
my Hickok 6000 and they both gave me similar results.. Cosmetics are ok. The
cabinet has some worn and tear spots in the cover cloth. I cleaned it up and
put some conditioner on the cabinet cover. It looks pretty good. .Pictures
are available. The panel is in great shape and shows hardly any wear. This
is probably the easiest tube tester in the world to use. There are only two
control settings, the filament voltage and sensitivity. . Included is a tube
data chart and a copy of the manual. There are several You-Tube videos one
an easy calibration of this model tube tester, although I don't think it
needs it . Price is $125 plus shipping. Thanks, Charlie Hugg, K5MBX
