Modified design by Kegger over at audiokarma.

Push pull 10GK6s in UL. 6GH8A driver/phase splitter.

Separate 6BY5GA power section for each channel.

Switchable between CCS or anode resistor for the driver. (although I can't get that to work yet for some reason)

Switchable between RC or LED cathode bias for the power section. Not enough listening time yet to comment on the difference.

I think they are cabinet handles. I have some in my kitchen.

Sure they are! And they were pretty cheap accounting the nice finish they give.

Haven't been on here in a while.So many outstanding designs,I don't even know where to begin....Welllll maybe I do,considering I too like to built in the steampunk style...

It took me over two years in planning and construction, but they're finally completed! It was as much an exercise in aesthetics, as it was for sound quality. That is to say, they sound at least as good as they look!

Fantastic work eboz!

The best tube amplifier I did.

My 845SE amplifier, basic circuit from Audio Note Ankoru but I adjusted to suit my system.

Very neat. Looks good.

Beautiful job nvduybom! Does the sound match your expectation?

@:mhouston & wlowes .

Thank you .

Sorry for poor English .


I love the sound of 845SE. Reviews for each frequency band, maybe it not good as several types of tubes I know (my reviews), but overall it is good and can play more of music genres. It is the best amplifier I've ever done.

Your english is ok . The amps look very very good.

Nice Oldies!

I like the trafos!!!

Cheers

 

[mhouston]

Oldies: 2A3 or 45?

 

[tomchr]

The front panel says 2A3.

That's a nice build.

7N7 Aikido

this is my new aikido preamp buid....

 

[boywonder]

PCB + pint-to-point

I'm sure the "pint-to-point" made for an interesting build........

 

[mhouston]

Tony: cool build.

 

[TonyTecson]

Tony: cool build.

thanks, 4 more aikido's coming, each one with different set of tubes....

 

[dady]

this is my new aikido preamp buid....

Classic style, 7N7 in a new topology one.
Classic style Chassis and point to point with one of the more linear valves.
Enjoy the music.

 

[scott17]

That's a nice build.

Thanks Jeff. I was skeptical at first about using the high-current blue LED array for the 10GK6 bias, but it really does sound good. Much clearer than the RC bias.

@Tony :

Looks good preamp .

I think the sound may be better with carbon resistors , especially resistors signal .
