Happy Thanksgiving!

Wow! Love that color. Congrats Wave!
 
Ouch... Listening to some nice smooth jazz I heard some clicks from speakers and thought that something is arching under the chassis in my amp prototype... But saw nothing wrong... Then realized that that were clicks of the vinyl playing by Pandora radio. :D


Had same feeling when i tried a new built riaa, there was some oddly wavey sound i never heard before on that record :D.

Nice looking amp btw.

When are you going into production? :eek:


Only Output transformers and chassis are original. Cathode auto bias with IC TL 783.

You do good work.:worship:
 
RCA 30+30 and others

Hello to everybody, I just check and saw very beautiful amp here.
I start just one years ago to build tube amp for myself. My first is the RCA 30+30 push-pull with RIAA and tone control, I am very happy with it, has been just difficult to squeeze everything on the same enclosure, if I have to do it again now I will for sure use separate enclosure, the second I call it "my baby amp" because is a little 1.3 watts using a TV vertical tube 6CY7 but the sound coming out of it and the clarity for do not talk about sound stage are incredible and very unexpected.
I then just last week finish a RIAA preamp using on the first stage 6922 and on the second 6N2P-EV, in this case I make a separate solid-state power supply with two different 240Vdc output and also two different 6,3Vac output so that I can use it with some future pre-amp project. All the best to everybody.
