NOTICE: The tube prices in this catalog CANNOT be compared to others!! Each tube sold by
V.T.S. has been LABORIOUSLY auditioned, scrutinized, and matched by Andy Bowman in the
V.T.S. Analog Laboratory using National Institute of Standards registered gear.
(See the Testing Laboratory, and Six Things, etc...)

Think these prices are high? Try the "Crazies"

RCA 6L6-GC Black-plate at over $445.00 a pair. That's over $220.00 EACH!!!!
For that price I hope the pins are solid Gold! (And the box too!)

12AU7

In the 12 volt family of popular preamp tubes, the 12AU7 has the lowest gain and lowest intrinsic distortion. In many instances, this tube can make magic if properly selected/prepared and truly
authentic. Here again is the cream of the crop in sound quality, reliability, and long life.

12AT7

The 12AT7 is the third member in the family of common 12 volt audio tubes. It has medium gain, but is the hardest of the three to manufacture and is the LEAST consistent of the three by far (meaning far higher rejection ratios)! This is a result of the very tight clearances between the cathode, grid & plate. At V.T.S. all 12AT7 tubes are matched on the fully calibrated RCA-WT100-A. This is the only machine with the precision needed to handle this tube. Here again is the best of the best.

Think these prices are high? Try "My Imitators"

Amperex 6922 PQ Gold pins at over $300.00 EACH and this is for a microphonic tube!!!
Why would anyone want a Microphonic tube especially at $300.00 each?????

Siemens 6922 Made in the 80's not selected at over $230.00 EACH!!!!!

Sylvania          6922 circa 1960's. Try some of these babies, one of the original "bad sound" tubes
                        at over $90.00 EACH!!!! Yikes!

6DJ8, 6922, 7308
(Frame Grid Tubes)

Amperex introduced the frame grid family of tubes in 1958. These tubes used a new technology of stretching ultra fine wire (.00029) over a stiff frame. They tend to be troublesome.. There are currently used heavily in modern audio gear. Here again while looking at prices, PLEASE remember that NO ONE ELSE IN THE BUSINESS has even HALF a clue as to properly select frame grid tubes for Hi-End audio systems! Because of this V.T.S. rejects many, many otherwise good and expensive tubes that others would sell you!!! Ever wondered why highly touted frame grid tubes like the 6DJ8, 6922, etc...sometimes don't sound so good, but can't quite put your finger on it? (even though they are authentic and measure perfect?) Well, while the "piss-willys" were spending the last four years trying to sell you Ediswan Brimar & other crap and 1970's & 80's Mullard for $50-$100 dollars each, O'l Andy was deep down in the sub-basement lab hard at work as usual figuring out why! You be the judge!

						made in the last 25 years.Made primarily for TVs,
						these were part of the first wave of
						electronics that helped Japan take over the
						U.S. Consumer electronics industry in
						the 60’s & 70’s. These are second only to the Four Euro Greats Amprex, Siemens & Halski, Telefunken & Mullard.

6922/	Amperex	1959-	Moving-Mag.	3	158.00	This is a rugged version of 6DJ8 for
E88CC		70’s	Super-Line	6	138.00	Industry & Military use. There were
			Line	4	128.00	two different plants that made
						these tubes. One in Holland and
						one at 230 Duffy Ave on Long Island
						New York. There were also several dif-
						frent versions from each plant. I do not
						have the time to go into them at this

						like fine jewelry. ((The antithesis of the
						currently made junk that looks like

6922/	Mullard	65-70	Moving Mag	8	148.00+	Same as above
E88CC	(Type 2)		Super-Line	12	128.00+	This is one of the most counterfeited

6922/	Mullard	70s	Call	Call	Call	Still a good tube but starting to slip in
E88CC	(Type 3)					sweetness now. (also see notes above)





6922/	Telefunken of	1970s-	Super-Line	2	12.00	I got stuck with these they, came in
E88CC	EAST GERMANY	80s	Line	5	12.00	with some other stuff. If
						you’ve paid more than this for these you
						need to find a new tube dealer! I know
						gobs of guys that have spent
						THOUSANDS on buying these from
						several of my imitators at around $150.00
						to $200.00+ each! Most said they never
						sounded right and went noisy after a
						week or so. Those who called and
						complained were told tough luck!

6922/	Siemens &	60s	Moving-Coil	2	178.00+	In keeping with tradition, the Siemens
E88CC	Halski		Moving-Mag.	5	158.00+	version of the 6922 is like it’s 6DJ8
			Super-Line			prototype. Super high information and
			Line	6	108.00+	all the typical attributes (see 6DJ8
				4	96.00+	Siemens). Watch out for the dreadful
						late stuff that’s pushed most of the
						time.

7308	Amperex	1961 &	Call	Call	Call	The 7308 was an attempt at further
	Mullard	later				refining the 6922 and featured tighter
	Telefunken					control of all specs. Fabulous tube if you
	Etc.					actually get good early production.
						While we are on this subject let me
						share with you a bit about testing these
						"Frame Grid" types of tubes. For as
						many years as I have been testing &
						studying tubes these have eluded me
						until the last few months. I can’t go
						into details here but now I understand
						MUCH more about these. It’s funny
						to think how most audio people
						and even tube dealers don’t have any
						idea why they get such differing sonic
						results from tubes, even those of the
						same batch.
