 Great sound!

This never been used, from the old stock.

Three reasons to buy tubes in:

1) Each tube shall be individually checked on the L1-3 military tube tester USSR before shipping.

2) Each tube is individually packed in a rigid package.

3) Most our tubes from old Army Warehouse. (New Old Stock) These tubes have improved quality and excellent life time.

Dear customer, you can combine shipping buying more than one lot.
