Nicely done. I'll bet that sounds incredible. Many years ago I had a Dynaco all tube stereo system. Music never sounded so good.

Very nice built , clean. Congrat .

Is it a kit or you do all by yourself ?

I wish to built a stereo power amp , I have a good tube preamp Conrad Johnson. Do you have on hand a schematic , low power push pull  ? I just need a shematic , I can do everything by myself .

Thanks for the good comments.
It is a very well known schematic from ELECTOR magazine.

Usually it is done with pcb. But i decided to do it  this way. and thank god it worked great.
The input selector and the tube vu-meters are the extras i have added. It is not in the original schematic, and both bought from ebay
The chassis and tolex cover is my design
