I especially like the looks of your 46SE ... Is that a kit or your own design??

This's not a kit .
tube 46 I bought from a friend , it cost usd40/pair
tube 12AY7 : usd 20/pair
SPU ang OPT : I wound them for a week.

Tonight, i'll show pic of inside .

This is also quite a nice pair: 845 SE tube amp .

Which is your favorite? Which sounds the best?

I don't believe I have ever seen such a variety of interesting amp designs. Keep up the good work ...

I use a BLH speakers with Fostex FE208EZ, so my choices are 46,45,2A3 .
The sound they come slowly, warm and good for relax at night .

Now, I use a pair of OPT made in China for 845 amp . I have a plan to change it with mine in near future .

Thanks for your attention !
