An easy & quick transaction
I chose the valves I required, which were in short supply due to the Russian invasion of Ukraine & they arrived within a few days.
My amp once again sounds thunderous!

Ordered a couple of 12AX7s for my JMP 2104. Emailed just over an hour later to say they'd been despatched. Well packed,very reasonably priced, and most importantly, sound great. Will happily use again.

From order online & delivered to my place in Hong Kong, it took only 9 days inclusive which is excellent.
The tube (6SN7) is of good quality and was solidly constructed but the design is different from Brimar NOS 6SN7.
Also the tube did not have any packing prior inserted into individual box and the marking on one of the tube is off centre. It might be a minor detail but I consider Brimar being a premium tube supplier.
Also looking forward to try the new version of TP-300B when it is available.
Many thanks as constructing a good quality tube is an extremely hard job. Much appreciate to all those personnel devote their passion in the tube business.

Ordered a quad of KT88 and ECC82 for my Primaluna Amplifier. They arrived quickly and beautifully packaged in waxed paper etc. Whilst Brimar are outsourcing their tubes at the moment to support future UK manufacturing, they are all matched well, at a good price and sound good too

Excellent product, extremely happy.
Put the valve on my amp the compression has increased, lots pf clarity on the high end and deep bass. I will order again

Bought to replace a set of 12AX7 of unknown age or provenance in a rack mounted valve preamp that I recently purchased.
Given the recent panic buying of popular audio tubes due to the situation in Russia, I was pleasantly supplied to find them not only in stock but also at a fair price.
Valves arrived very quickly and well packaged.
They work as well as anything else, but the peace of mind of having a new professionally tested set is worth the price alone. It's a pain to undo the rack to replace them if they failed, so hopefully this should prevent that occurrence.
And it's helping to support a very worthwhile endeavour.
I'll be buying all my valves here in the future.
Thank you!

Excellent service, Bob does an awesome job, totally recommend their products and service.

It was a pleasure to deal with you.
Great sounding valves completely transformed my old Mesa Boogie.

Messed up with the postage but refunded me for it.
Great tubes

I have used the new production Brimar thermoionic Valves for the preamp and now power section of my integrated amplifier.

I am stunned by the accuracy of the sound resulting from their valve designs and am very happy to incorporate their products in my system. True music matters to me and these products delivered that.

Thanks Brimar Thermoionic Products UK Ltd

A very expedient delivery. I was also impressed by the close tolerance of matching for the the EL34 quad.

Used these valves in vintage guitar amps and HIFi amps and the results are amazing!

Excellent Tubes with amazing performance over price ratio! Shipped halfway across the Globe from UK to Malaysia with no issue. Will be ordering direct from Brimar UK again for sure, Many Thanks!

Really pleased with the service. Quality tubes (I have guessed the origin) and although fractionally more expensive, I know that the proceeds are going to a great venture, for which I wish them nothing but the best. It would be great to see quality British tubes in production again.

The products are great, excellent quality, even packed in the original waxy Paper. So nice to see production on the UK. Keep it going
Will use them for all my Valve requirements.

Smooth transaction, reasonably fast delivery considering the times. Haven't tried out the tubes yet!

I bought tube 6sn7GT for my headphone amp. I think It is difficult to review the tube as good or bad because it might be based on good or bad synergy with the headphone system although tube itself might be excellent. In my system the tube delivered more pronounced bass and subdued highs and therefore female vocals were sounding like in the background, the lack of highs was apparent. Classical music was also out of the question. Otherwise, the bass and midrange sounded beautifully in my system and if those highs would not be subdued this tube would be my favourite without any hesitation. Tube was sent by producer next day after placing the order.

Excellent product and service....recommended! Customer from Singapore.
