Hi all, I have a couple of Skytec Tubesters that I'm never going to use. One is ST-104, V11, S3 (yellow dot, 7 pins) and the other is ST-202, V5, S3 (blue dot, 9 pins). Each $20 shipped free USA, elsewhere actual shipping cost. Removed from working 75S-3B. Please reply off list. Thanks for reading and 73 to all, Mike W2IY.
