These kits are sold by valve layout, not by amp brand. Use them when you already know the complement — for example how many ECC83s sit in the preamp, whether one of them should be a balanced phase inverter, and which power tubes the amp needs (EL34, EL84, 6L6GC, 6V6S, 5881, 6550, and similar).
Brand pages under Choose Your Amp list kits by brand and model. This category is the opposite: plain matched sets for builders, techs, and players who prefer to order from a valve chart or a previous install rather than from a logo.
Every kit here is built with JJ tubes, matched where it matters for the power section, tested before dispatch, and shipped from the UK. Browse the list for your exact count and mix. If nothing lines up you can create your own kit by visiting our Choose Your Valve section.

If you can't find your amplifier listed or the specific valves you are seeking, just drop us an email from our contact page. Remember, even the best amplifier in the world will sound poor if the valves aren't replaced regularly.
Finally, you'll be pleased to know that good quality valves for amplifiers are relatively cheap but the difference they will make to your sound is huge. So order a set of brand new valves for your amplifier today and hear the difference.
