I have the following slightly used tubes for sale:
3 only Eico 7591 made by Westinghouse
1 only GE 5U4GB
1 only RCA 5U4GB
1 only Realistic 5U4GB
1 only 6CA7 / EL34 made in Japan
1 only Philips 6CA7 made in Great Britain
1 only Toshiba 6L6GC made in Japan
1 only Sylvania 6L6GC made in the USA
1 only Sylvania 6L6GC made in the USSR
1 only Realistic 6L6GC made in Germany

Note the Realistic 6L6GC is new and never been used ( except in a tester) and was purchased by me when Radio Shack ceased selling tubes. I paid $19.95 for it in the middle 70’s.
All tubes have been tested in a TV-7U C and/or a Jackson 648-1 and are shown to be in very good condition.
Price is $100.00 for the tubes and shipping will be about $50 to just about anywhere in Canada.

All comments , questions or offers should be sent to
Thanks
