AMPEREX GOLD PIN PQ 6922's are the most sought after tubes for a reason.........the sound. These deliver absolute heavenly bliss!!!
So..... here they are......these are the tubes you have been looking for! These are  AMPEREX PREMIUM QUALITY PQ 6922's. A near perfect pair with no wear or blemishes and they sound perfect (tested by me). For audiophiles these tubes are the sweetest sounding tubes made.  Once they are gone I have NO MORE. You may never see tubes like this again. I have only ever seen a few in all my years.
Here's what tube guru Brent Jesse says concerning these tubes:
"This is probably the ultra 6DJ8 type tube commonly available. It has all of the features of the 6DJ8, but the triode sections are also matched to each other, and the tubes all fit within very tight specifications. Therefore, any 6922 should match any other 6922 within the same brand. The Amperex versions were again made in New York, complete with gold pins, and often have a number etched into the side of the glass. Amperex made these for industry as well as the military. The Amperex versions have the PQ label, the military type usually is labeled "USN_CEP", but I have seen versions made for Stromberg-Carlson and Hewlett-Packard, with white ink labels. These all had the numbers etched into the glass, and all are the same tube. The USA made military white label types have been rated "Best of All", over other 7308, 6922 and even Cca tubes, in several well-documented 6922/7308/Cca listening tests. Therefore this particular type is becoming scarce and prices are rising. There were a few of these made in Holland, but most were made in the USA, therefore the Holland tubes are RARE and usually command a higher price. The Holland PQ versions have the PQ with stars on either side of the letters, and the words "Premium Quality", where the USA types have the PQ inside of a shield logo.
Rated "Best of All" in 7308/6922 and Cca listening tests! Maybe that is why they are getting so scarce !!!!
On my tester a B&K 747 tester:
Below 55 = BAD
55-66 = ?
65 -100 = Good
100-120+ = NOS
I want to see you happy with your purchase. I will never sell a tube that is below standard……
I have sold many tubes here on Ebay, and all my customers have been completely satisfied. I will work with you in good faith if there are any problems, or if you are unsatisfied in any way.
I want your business now and in the future, so I assume you are the boss, and I am the employee.
All tubes are tested for shorts, continuity, and emissions.
I prefer PayPal.
ALL CUSTOMERS PLEASE READ ALL NOTES BEFORE BUYING FROM ME !!
1.  RETURNS: It is my highest desire that you are completely satisfied with your purchase from me. I will bend over backwards to make sure that you are a happy customer.
If anything you buy from me is less than satisfactory, message me BEFORE you either open a case or hit the “item not as described” button.
Sound quality is tremendously
SUBJECTIVE
. For tubes returned for "noise" or "sound quality of any kind" you pay for the shipping we refund the purchase. We refund the price of the item NOT THE SHIPPING COST. If we sent the wrong tube we will of course pay for return shipping. For any tubes that are DOA we require that you send a us a picture of the shipping box to show us the damage. We test EVERY tube sent out and none should be DOA unless broken in shipping.
2.
PLEASE NOTE:  Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. If you wipe off the silkscreen while handling the tube you diminish their value by up to 70%. DO NOT handle the tubes or hold them from the cylinder. ALWAYS hold them from the ENDS. If you are returning tubes and they are not in the same condition cosmetically I cannot give you a full refund. THIS IS VERY IMPORTANT.
3.  UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!!
4. TESTING: I test all tubes that I sell in one way or another, or I will state "untested". I have a B&K 747 tube tester. This is a mutual conductance tester. It give a percentage value of gm for the tube under test and checks for shorts and grid emissions. I also use a Tektronix curve tracer for testing triodes. I give a number of evaluations for tubes. One evaluation is a screen shot of the tube with a high voltage applied to the plate. This helps the buyer see the linearity of the tube in question at the highest voltage the tube will see in a real circuit. The Curve tracer steps the triode through 10 gate/grid voltages starting with -10 volts and going to 0 volts. The lines show how the tube conducts throughout that range. At 0 volt the tube is at max conduction and is the top line on the display. It is easy at that point to take where that top line intersects the plate voltage, find the milliamp level and compare it to the datasheet. I give those numbers for you in the "Item condition box". To further help the buyer I also include the "Design values", for gm and ma readings in the table. This can then be compared to other tube sellers using inferior test methods such as Hickok,
Amplitrex, and other testers. The Tektronix curve tracer gives values within 3% of the actual value. The very best portable testers only can approach 10% accuracy.
5.
Please note: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I don't guarantee or imply anything else.
6.
VERY IMPORTANT!!!
Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage.
7. I don't check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you don't like the noise level or the tone we offer a hassle free refund policy.
International customers note:
1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue.
2.
Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws.
3 International buyers if you bought more than one item and want combined shipping it will ship in 2 days.
4. And all the Angels sang because the heavenly music was playing and it was turned all the way up.
