Have anyone tried 12ay7 tube in ha6a ?

It’s a great amplifier, I liked very much.

Try 5u4gb tube

Someone know if other pads different from the originals fit on the rad-0?

No I mean eat kt88 made by European audio team

Have something tried eat kt88 ?

Hi, has anyoke tried lcd-5 pads on mm-500 ?

Try eat 300b

I’m using EML 2a3s power tubes but after some test with a lot rectifier my preferences goes for mesa 5u4g, that is a Chinese tube but highly selected. I try eml, kr, Sophia rectifier tube, I think that rectifier tube must be choice in conjunction with the power tubes and personal preference

I tried eml mesh, eat, kr, without any issues. At the moment I’m using takatsuki 300b but I think that this is the definitive setup

I don’t know the specs, but if you listen the two amps side by side v1 sound a little better, headphones used in the test was hd800s and Audeze lcd-2 rosewood 2022

I think that if you find used at a good price is the same, I suggest you to find a v1 because it has a better construction but better output transformer. Remember that you have to spend some money for the right tubes

Merry Christmas to all wa33 owners

I found a great synergy with lynx Hilo, it return a great transparency to all headphones like STAX offer as standard
