Valves come at a broad range of prices. Our recommendation is to buy in the middle of the price range. (don’t buy the cheapest ones, but don’t waste your money getting ones with gold pins or “signature version” or any other such brand differentiation – the insides are all the same!)

As a guide, a set of four EL84 output valves – the ones in most of our amplifiers – should cost around $100-120 USD.

There are many sources of valves available. And, there is no such thing as a valve that’s been made for guitar or hi-fi usage. So if you want, buy your valves from a guitar amp supplier with complete peace of mind.

As at May 2023, these are the prices available from thetubestore.com which is the online supplier we recommend for good prices and fast turnaround.

EL84-type: $USD 30 – 50 ea.
EL34-type: $USD 30 – 80 ea.
KT88-type: $USD 70 – 120 ea

You can pay a lot more for valves, don’t let us stop you, but it’s really not necessary.
