Group of 8 GE 5* 6072 Vacuum Tubes Triple Mica Black Plate Same Date Code AMPLITREX Tested [SALE PDG]
PLEASE READ THIS LISTING IN ITS ENTIRETY, INCLUDING ALL TERMS AND CONDITIONS!By purchasing from this listing, you acknowledge that you have read and understood this entire listing, including all my terms and conditions, and agree to accept and abide by those terms and conditions.
I am cleaning out some stuff, and I have several 6072/6072A vacuum tubes.
For sale in this listing is a group of 8 GE 5 Star 6072s with black plates, triple micas, internal supports and slightly tilted halo getter elements.
Price for the group is US$550.
At my asking price, domestic shipping (USPS Priority Mail) is included in the price, and a comparable discount will be given on international shipping. More shipping details are below.
These all have a common printed date code of 60-12 (there is also a second date code on each of 61-52). In other words, they all appear to be the same tube.
Printing is in general decent on all of these as can be seen in the photos.
I tested all the tubes on an Amplitrex AT-1000 (connected to a regulated power supply). The tubes were tested in fixed bias mode, and the test cycle was run at least twice for each tube (better warmup time and stabilization). The test parameters were Vp = 250V and grid = -4V. Spec transconductance (Gm) on the AT-1000 under these conditions is 1.7 mA/V. Test results are as follows:
Tube #1 1.7/1.6
Tube #2 1.7/1.6
Tube #3 1.7/1.6
Tube #4 1.6/1.7
Tube #5 1.6/1.7
Tube #6 1.6/1.6
Tube #7 1.6/1.6
Tube #8 1.5/1.6
They are all reasonably balanced and at least seven could be considered closely matched on Gm (with the eight not too far off). Alternatively, there are four good pairs in this group.
A quick note about microphonics – all tubes are little microphones and are microphonic to some degree. Whether an individual tube is unacceptably microphonic or otherwise noisy in a certain piece of equipment is anyone’s guess (and generally subjective). The Amplitrex does have a headphone jack for checking noise/microphonics, and I have used this to check these tubes while testing. These tubes do not (in my sole and uneducated opinion) appear to be abnormally microphonic (and actually seem to be very low on the microphonics scale). With almost all tubes, you can hear the tap of a pencil to different levels. There were some with a little more tap noise than others, but none sounded like church bells in a canyon (or even remotely close). My opinion is NOT, however, an indication of how these tubes will sound or perform in your equipment and, as detailed below, there is absolutely no guarantee against microphonics or noise under any circumstances.
For the purposes of this sale, all of these tubes should be considered USED.
I can provide additional information or photos on request.
GENERAL TERMS AND CONDITIONSPlease note that these tubes are being sold

UNLESS I have grossly misdescribed what I am selling.
Notwithstanding, I am an honest seller (please check my feedback on EBay, ID=baileyler), and if there are truly any issues with these tubes that were not described (other than microphonics/noise) and can be verified, then I will work with any
reasonable buyer on a
reasonable solution.
For further clarification, I ONLY describe what I know about the tubes, and what I have tested for. While my tube testers tend to be reliable, YOUR TUBE TESTER MAY GIVE A DIFFERENT RESULT THAN MINE, so please take that into account. In the event of a tube tester conflict,
MY TUBE TESTER CONTROLS.
