Product Description

EH 300B Matched Quad

The Electro Harmonix EH 300B Matched Quad are an excellent choice .

The 300B was introduced to the market in 1938, so it must be good as it is still  in production today !

Ultra-long life, high-quality construction and superior sonics with improved performance make it a top choice over 300B types made by other manufacturers. Like the original Western Electric 300B, it has the eight course, directly heated filament, 40 Watt plate dissipation, classic large-shoulder tube glass, and is available  in precision matched pairs and quads. The EH 300B  plate curves and static DC characteristics (plate resistance, transconductance, mu) also exactly match the original’s for superior performance in any vintage or modern 300B amplifier.

The valves are accurately factory matched . The factory tests for the mutual conductance and the current and these are attached to the top of each valve box. The test conditions are printed on the bottom of each valve box and you can see these in the picture.

These are made with real care and is the perfect choice for replacing tor upgrading your quality hifi amp

We also give a 180 day from receipt warranty on the product ( excludes  user caused mechanical damage ) for peace of mind

We have shipping options for UK and international customers.  Just make your selection at checkout. Get your valves delivered faster!

"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
