I picked up a Tube Tester at the Near Fester...
an EMC (Electronic Measurement Co. of NYC) Model 206. in a wood case, case is pretty beat, but the innards are in good shape.
It has the scroll with all the settings, and actually works. BUT (theres always a but)
I need a manual, or can someone tell me how to set the switches to get power to the filaments???
There are no settings on on the scroll for how to select the filament pins. I managed to test a questionable 6sn7gt that I had, after a lot of guess work about the unused switches, got the filaments to light, and got a reading that about matched my opinion of the tubes condition... (yea thats real scientific for ya
but hey it works!! and for $10 yet!! )
