In order to avoid misunderstanding please take note THE PRICE IS FOR ONE QUARTET and two quartets are availables.
When it is said that a certain valve is nowhere to be found it is almost never the truth.
I have many single tubes that show that almost everything paid at the right price is still available.
But the rarity of a tube grows exponentially if a matched couple is needed, in some cases it has practically become very very hard find a quartet
IT IS ABSOLUTELY UNABLE TO FIND EIGHT KT88 PRACTICALLY WITH THE SAME VALUES, NEW, NEVER INSTALLED, WITH THE ORIGINAL PACKAGING AS THESE PROPOSALS
A LUCK SHOT AND I HAVE COME AWARE OF MY OLD CUSTOMER THAT STILL HAD A CERTAIN QUANTITY, I PAYED ITSELF TO GOLDEN WEIGHT, I WAS ABLE TO CONVINCE HIM TO SELL ME EIGHT.
These are valves produced for Mullard (even rarer than those of the manufacturer's brand) by G.E.C.
the famous M-O Valve company LTD English.
All of the same lot and all produced in 1968.
You can see the test values at the bottom of the page
NOTHING COMPARABLE ON THE WORLD MARKET AT THE MOMENT.
THE SELLING PRICE, OF COURSE, IS VERY EXPENSIVE BUT JUSTIFIED FROM THE ABSOLUTE RARITY
