Excellent condition!
I just completed
servicing and calibration of this
early & popular tube tester.
Includes my re-mastered, reprinted instruction manual, updated tube
test data book and the original
set up data lid chart (more than a $50.00 value).
Clean, tested and calibrated (ready to use) and
satisfaction is guaranteed. The only
negative item would be the case finish shows some wear and some
paint chips. Some of the panel screws where missing and mis-matched.
I replaced them all with nice matching screws.
The I-177 will test all the
consumer and military (except the larger transmitting types)
tubes from the 1920's to around the mid 1960's with the
exception of the 9 pin miniature based tubes (such as a 12AX7).
It will not test the newer TV types that were introduced in the
late 1960's & '70's like compactrons etc.
