The amps look great!  I'm just starting to think about my first build, some great inspiration. subscribed.

Building new amp. Weights already over 10kg. Power Transformer is from that rather ugly 6SN7-6AS7 amplifier. With this amp that transformer looks much better.

Still waiting for 6BY5G rectifier tube. RCA 6SN7GT tube is just there for photography. This is going to be "normal" stereo amplifier with headphone output too.

Some progress. Don't know where camera found that greenish color...

 

I left some space for future improvements, like another RCA line in and more switches. Tomorrow i could begin soldering parts inside with my 15y old cheap soldering iron and that is much more fun than making chassis with not so proper tools. Drilling holes for tube sockets was easy with my new step drill. First i was going to paint plates, but after seeing amp outside ready i gave up on it.

It works \o/ ! 

:beerchug:

 

Newer 6BY5GA rectifier tube does not look that bad. It does have pretty strong glow. I also have older coke bottle model 6BY5G.

 

There is relay that disables speakers, if headphones are inserted. I have to be careful not to burn my headphones accidentally, this amp is capable to do that. Need to find a way to lower gain if headphones are inserted.

 

Frequency response seems to be flat between 10hz-20khz, so everything is working as expected and inMADout output transformers seem to be very good for the price.

Nice work as always.

Some fantastic amps, I'm more or less worried about causing a fire and burning down my apartment. 

Good Job guys!
