상품 설명
One Rare NOS Military Tungsram 12AX7 / 7729 / ECC83 Tube. The tube has 2 extra metal supporting rods to reinforce the internal structure and to reduce vibration & noise. The tube is sometimes marketed as 12AX7 and sometimes as 7729. Tube pins might be gold plated - not too sure about that (please check the photos for detail).
* Minimum good for 12AX7 tubes on TV-7D/U is 32 (65% of NOS), so
Below 32 = Low testing tubes
32 - 49 = Good tubes
International Buyers - Please Note:
Return Policies:
Tube has been tested on our military TV-7D/U mutual conductance (Gm) tube tester, which was recently restored and calibrated by Dan Nelson - the King of TV-7 series tube tester calibration and restoration. TV-7D/U test results (also refer to photos for measurements):
- Tube Gm: 60 / 56
* Minimum good for 12AX7 tubes on TV-7D/U is 32 (65% of NOS), so
Below 32 = Low testing tubes
32 - 49 = Good tubes
49 and above = NOS tubes
So the tube tests very strong.
No shorts, no leakage, no gas.
Tube and tube pins have been thoroughly cleaned before plugging into our tube testers and tube amps, so it is ready to use right out of the box.
Tube will come with original military brown box and wrap (as pictured).
Shipping:
- Tubes will be shipped by Canada Post Small Packet by Air, unless otherwise specified. It normally takes 5 - 10 days to get to US addresses (2 days within Canada, 1 - 3 days to cross the border, and 2 - 5 days within US via USPS Priority Mail).
- Shipping fee to Canadian addresses is US$15.
- Combined Shipping is welcome, if multiple items are purchased. If items have been paid separately, we will automatically refund any savings from Combined Shipping.

Folks in other countries please inquire first before hitting the BUY button. No shipping to China, India, Indonesia, Vietnam, Italy, Russia, and so on due to lots of reports on lost packages at customs.
Return Policies:

- Our purpose here is to sell tubes instead of loaning tubes for rolling. To discourage tube trial there will be a 10% restocking fee. Serious buyer only!
