You are looking at a beautiful NIB pair of 1940's RCA Black Plate 6SN7GT's with offset flat black plates from batches 409 and 413. The tops are clear confirming that they are unused, the glass and pins are tight. They are in lovely condition and measure much stronger than new and well matched between plates and each other on an AVO 163 tester for current draw and mutual conductance. Tube 1 - 11.2/3.2 & 10.6/3.0 and Tube 2 - 10.2/3.0 & 11.6/3.2. Nominal new measurement is 9.0/2.9. Buyer to pay actual shipping costs only, insurance is available.
