help using Tube Tester

ebarker2 · 30th January 2004, 11:05 AM

I’ve been loaned a US Army (surplus) Signal Corps Tube Tester 1-177-B made by Tripplet Electric and a Tube Socket Adaptor Kit MX/949A/U. Unfortunately the lendor can’t find the instruction manual at the moment.

My power amp has gone, and I’d like to test my Sovtek KT88’s. Does anyone know of a simple method of doing this using this machine. Its 120 volts and I will have to use a transformer, being in the UK.
Thanks

thanks Dave,
Do you think a 1650watt transformer is enough?

I doubt a I-177b draws even a forth of that so it should be fine..I wouldnt be surprised if the I-177b has 220 taps on its mains transformer but I wouldnt swear to that
