Description

Nice set Rogers tubes. Test 70.5 and 72 Testing is done with Superior TW-11 Tester. This tester is a cathode emission tester. The results are useful for relative matching of same type tubes, and also a good/bad result. Tubes are checked for filament continuity. The results should be taken as a general indication of tube health. I am happy to combine shipping on multiple purchases. If it is just tubes, I will ship up to 5 lots for the single highest price of the tubes purchased. Please wait for an invoice before paying. You will find the invoice once issued in your shopping cart.
