At Fuzz Audio:

·     All tubes are tested on a calibrated Hickok 539b.

·     3 Day Money Back Guarantee For Faulty Tubes

·      All power and preamp are tubes tested for Mutual Conductance (Gm)

·      Do not buy power or preamp tubes that have been tested solely on an emissions tester or “tube checker”- this is an inadequate test.

Joint Army Navy (JAN): No but industrial

Notes: Best 12AX7s ever made by far-hands down- don't hesitate before these go. We do not have more of these in stock. Largest date matched group we have seen. These are INDUSTRAIL NOS!!! and Date Matched. ALL GM READINGS ARE EXCELLENT AND SOME ARE NOVAL.

Contrary to popular belief- roughly 70% of all manufactured vacuum tubes did not come individually boxed. VIVA tubes gets this wrong, shows what they know… Most tubes were manufactured for industrial use and therefore tubes were shipped and stored in large cardboard boxes with lipstick dividers.

Test Results: 
Tube 1: 1700 | 1700 Gm (Novel)
Tube 2: 1600 | 1700 Gm (Novel)



Matched tubes should be within 8% Gm value of one another (does not apply to pre-amp or rectifier tubes).

 

Minimum Good Value: 800 Gm
NOS Test Value: 
1000 Gm

100% x 2

Sound Test:  10 | 10 | 10| 10

Scored 1-10. 10 being most silent

True NOS?*:
Yes

 

**Our Testing Standards:

Fuzz Audiotests each tube thoroughly.

-First we use a B&K 607 Emissions Tester for leakage and shorts.

The 607 is one of the best leakage and shorts testers made. It’s leakage test is extremely sensitive compared to a Hickok’s and adds 8 more short tests to the Hickok 539B’S 5 short tests.

Next, after a tube has passed testing on the B&K, we test for microphonics, mutual conductance and preform the Life Test on a calibrated Western Electric KS-15560-L1(Hickok 539B).

Hickok 539B tests include:

Sound Test- During the Sound Test, 5 additional short tests are conducted as each tube is tested under real life conditions, connected to a sensitive radio antenna and listened to (the antenna picks up even the smallest discharges of current flow that would not power a light indicator or register on any multi-mete). Of course, we do this to make sure the tube has no unwanted microphonics in the tube.

Nextis, the bread and butter, patented Hickok Gm test:

The 539B meter reads in Gm instantaneously on the most sensitive Gm tube tester ever made. No random numbers that require you to calculate backwards, forwards or sideways. We give it to you in Gm and accurately. If someone says Gm value 92 they either need to do some more calculations for you or the tube is bad. A typical Gm value (especially if the tube is good) is above 1000. For example, a 6v6 has minimum Gm of 2350.

The very final test we conduct is the life test:

With the Gm test button depressed- the current flow to the tube is reduced by 20%. Hickok says that a tube “passes the life test” if the tube reads no less than 20% of its original Gm value. At Fuzz Audiowe reject a tube with > 5% depreciation of initial Gm value or label it used.

****However, understand that to truly know how a tube will perform you have to plug it in and use it! With that said, we offer returns in the off chance we missed something- but it hasn’t happened yet!******

Shipping:

All orders shipped within 2 business days. Enquire for express shipping. International shipments MAY take a few weeks to arrive.

Tubes are packed with utmost care.

Return Policy:

3 day returns for any complaint.
