I have over 100 pieces of vintage 12AX7/ECC83 tubes:
22 pieces of Telefunken 12AX7/ECC83 Tubes made in W. Germany with diamond imprint between pins.
- 6 are ribbed plate
- 16 are smooth plate
10 pieces Amperex from Holland, 6 are Bugle Boy.
13 pieces Mullard from G. Britain. 4 are 17mm long plate.
Send me your offers/request and I'll try to match them using B&K 747 tube tester. I only sell you the tubes tested strong. They are not priced exactly the same, depending on the tubes you request. $35 is a reference point.
I also have about 60 pieces of USA 12AX7, at least half of them have square getter.
I welcome local cash transaction. I also know how to pack for safe shipping. Paypal for distant buyer is OK, but please add 3% (international will be 5%).
