Item History & Price

| UPC: Does not apply |
Up for sale here is this vintage National Union 6SN7GT tube, Made in the USA and dated 1951. This has black glass and looks really cool.
I tested it on my calibrated B&K 747B tube tester, and it tested at 24/38, with no shorts or grid emissions, on a scale of 0-120, where 65 is minimum good and most 6SN7 tubes test in the 40-60 range. This is a pretty low tube, and it might work fine, or it might not work. The base has a hairline crack, but that won't affect an...ything. Please see my pictures for details.
US shipping and handling is $4, and international is $16, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. I accept Paypal. If you have any questions, please ask.
I have more tubes and other vintage electronics listed--feel free to take a look!
