used this in a custom overdrive build and sounds excellent. as good as any of the 12ax7 tube drives I've built and just as cool looking. very happy with my purchase!

I have not started my pre amp yet,but I am enjoying my ACA and ACP very much.Thank you very much for your note, the store and your products! Later, Grover

Great parts, very fast service. Definitely would be shopping again! Thank you very much!

I grabbed a matched quad of the LSK's for use in a cloudlifter-type circuit and they worked great! Low noise as expected

The P.S. boards would be a bargain at twice the price.
Board quality is outstanding. .And diyAudio staff are patient, and helpful. ( I had to order twice, because the first time I kept making errors entering my own address!. Staff helped me get past these errors, and on to a new order.). Boards arrived very quickly, and in perfect shape because of the care taken in packaging.

Loved building it and the help from the forum was amazing. They diagnosed an issue I had with the second build.
Support from the DIY store is lacking. They do a good job just take a very long time to respond so best use the forums to get answers.

I build two of these and it was a fun project and the sound is amazing. I love class A pass designs.

The kit was fun to build, but the performance is the main reason to get it. This amp has a big, open sound with tons of detail that doesn’t cause fatigue. Great bass response and control as well as incredible imaging. I have it paired with the Bellari PA 555 tube preamp and Decware DNA speakers that I built from plans purchased from Decware. The speakers have never sounded so good!

I am very satisfied with the product!

Really good and fast service - high quality parts accurately matched.

Many Many thanks to Elena for actively helping in managing the international mail service failure. Other suppliers would not do this!

Having recently built a ACP + and decided to use a Meanwell internal 3amp SMPS. I already have a lot gear using linear supplies, as I have been wary of using SMPS supplies in the past and putting out 'gunge' into the supply. However, I am thinking things have improved in their design and a lot of audio manufactures seem to be using them now as well. And as I like leaving stuff on, I thought why not try and save a few dollars on the electricity bill. This filter is very well priced and easy to implement. Not sure how much difference it makes but the ACP+ sounds very good to me.

This is the tube in the B1K and I loved the sound so much I wanted to make sure I could keep it going when the tubes finally expire. Hoping that's around another 20 years or so.

I ordered Toshiba NP Quad with PCB and F-5 Transistor Kit. I haven't used these yet, because I'm still
in the part collecting phase for my F5. The delivery to Germany was faster than I thought and well packed
with care. Great service and superb quality. Thanks diyAudioStore for making things possible!

Arrived in perfect order. Boards well
Made. Have not had a chance to start work as yet.

Just so. Perfect.
