Product Description

EH KT88 Matched QUAD for guitar and hifi amps

In 1957, the  Marconi-Osram Valve Company introduced the “King of Power Valves”, the legendary KT88. This tube became the heart and soul of  many classic amplifiers

The Marconi-Osram Valve Company ceased  production in the early 1980s and the original NOS  KT88 has become very expensive and hard to find.  Supplies have dwindled to almost zero.

The Russian valve factory in Saratov has produced this superb performing KT88 under the Electro Harmonix brand

Now we have a KT88 that is again providing the sonic sweetness of  original KT88’sand it is now back in continuous production.

We test and ensure quality matching on our Avo testers and we supply a test certificate. We test at real voltages found in your amp. 180 days warranty

You will receive four KT88’s.  We also have this product as a matched pair.

You will love this EH KT88 Matched Quad

Fast international delivery options are available at checkout.180 day warranty covering workmanship faults

"I’d spent some time upgrading my Blues Junior mk2 with better-spec components; larger pine cab, Cannabis rex, caps & resistors. What difference could alternative preamp tubes make? Well…I’ve already thanked Stewart for hooking me up with these beauties. 7025’s in the V1 & 2 sockets really have cut background noise to pretty-much nowt & any ‘loss of gain’ (I use pedals for this anyhow) is made up for by being able to play at increased vol & greater clean headroom. I lik’em & you might too!." - MH bought EH 7025's and reviewed on 18th July 2021
