Knight KG-600B Tube Tester
Excellent shape - just missing top cover.
Internal chart included. Good working condition.
Will sell for $50.00 plus shipping

OK U guys without any test equipment ... here is a toob tester
for 50 bucks.... Brian didn't put any pictures of it on his
web site... so ask if it covers the 4,5,6,7,8 pin old style
tubes ... I am betting it does..

I believe it does, but what you need to ask is whether it is a real
transconductance tester or just a mutual conductance tester.
