Take a look at these two lovely NOS KT66 we have at the moment. They are dated 1940's and come with their original boxes. We have four on sale. The first two have the box with the letter L and CV1075 on the other side of the valve. Tube test a smashing 75mA current working at 6 Volts. You must not miss this lot. Identical construction. Price £ 120 each. Unboxed NOS £ 100
Four KT66 Types L and Z
It's a good idea to have two valves with black base you can use in the left channel of your amp and the other two with brown base for the right channel. These four valves are about 5mm taller than any common GEC valve. If you are looking for NOS tested and matched valves we can offer such a lot of 4 pcs for only £ 400 either black or brown base

KT66 Marconi: THE POWER AND THE GLORY
Our beloved Guglielmo Marconi made such a tube (and many other) like no one else did! that's for sure. Showing you some of the Marconi KT66 we have for sale at the moment. Like the other KT66 shown above these valve are taller (around 5mm) with superb plate and construction glass . We have both Black and Brown base for £ 100 each
6L6 USA made = Direct Equivalent of a KT66
If you are looking for  valve that's built with passion and all it's ingredients the 6L6 is for sure a superb type of Pentode even wortking at higher HT than a KT66. The Anode Volts rates at 350 keeping the Screen volts at 250 with  Ia mA of arounf 54. That's what we experienced with these valves. We have stock of 12 pieces. RCA, Sylvania, Tung-sol. Price each £ 50
Other types of 6L6 and CV1075 by Cossor
The story goes on with more 6L6 here shown which virtually are of the same batch and year of the ones above. This means same HT and Voltage filament etc. We have added a rare Cossor CV1075 (and that's the one on the right). Please note the ribbed plate as well  the top featuring a semicircle metal rod for keeping the whole cage! £ 60 for such a valve cool valve
More 6L6 and CV1947 made in England
We have digged out some CV1947 manufactured by Brimar in the early 50's. Having the brown base you cannot go wrong, tubes are vintage and at their best. The KB/FB printed around the base is synonym of excellent quality. The coating for both valves is still intact. Tubes have been tested with satisfactory results 54 mA. Price left £ 50 each. Right £ 45
The best selction of KT61 Marconi Osram GEC
Tubes like appear every now and then! Yes we have stock for each of them although no many left but would say we can easily combine a match quad! The KT61 is widely used in output stage of radio or commonly in the Leak TL10 point one. It's direct equivalent of EL33; 6A6G and CV type is 1438. Rare types those with brown base from £ 50 each only! NOS boxed MINT £60 each
Ultra-rare KT61 Marconi GEC with metal base
This is the bunch to die for! No doubt you are viewing one of the most desirable KT61 available those days. Very old nostalgic tubes all coated and been tested to verify their parameters, data and condition. We can tell you from now on these 4 tubes are mint and test as perfect as a ruler! with Ia mA of 40. Price each £ 70. There are 3 pieces left...grab them before it's too late.
More KT66 boxed the OSRAM long type
As referred above there was a copious batch of KT66 made those days (1945+) by the Marconi/Osram work. Apart for the elegant box and look the Osram was clever enough to produce distinguished valves with ther own mica and inner design. Very simlar to a KT66 GEC but would say more trendy! Stock of 4 or more. Extremely rare. Price £ 140 each
KT88 GEC valves that come and go easily
It is amazing how the KT88 has been so far (by popular demand) the best selling KT of its kind. There is a multitude of amps that use such a powerful Pentode and many of them require 8 x KT88 per channel. Can you believe that folks? You gotta spend your own entire wage to power your amp(s). We have only two. SOLD! Price boxed £ 150 unboxed £ 100
KT66 GEC the original Clear Glass one
"As cool as a summer breeze" the KT66 by GEC is among all those shown the most common one. There are two versions of this valve. The double getter and the inverted getter. No matter! they both play great and are very much loved by our Japanese and Honk Kong friends. Used in Quad II Leak 12.1 and many other vintage/modern amplifers. £ 95 each
