My Baby, waiting for better OPTs...
EL84 PP Class-A

This is the best amplifier that I have done, the circuit based on the amplifier Audio Note Ankoru but I used SE.

Hi nvduybom, the amps are amazingly beautiful. Ankoru are pushpulls, Did you tried with the aurora project of Gary Pimm and Lynn Olson? If you aboard this monster project try to find the info and try to build It.
If you build like that you gonna get the heaven. And of course Its redemption.

Dual 6C4 driving a 6N3C Single-ended

I just finished this. It sounds great and now I'm in the process of building a pair of full-range speakers (Fostex FE166En + BiB) to mate to it.

Do you mean 6S4 (single triode) and 6P3S (tetrode) (latin spelling)?

Hi,

No its an RCA 6C4 (single triode - I have a lot of these) and a 6L6GC clone (eBay seller claims a "Russian Reflector Factory 6N3C"). I think they were about $11USD shipped. They sound nice and aren't too gassy.

Ok. So it is 6П3С, also noted as 6n3c.

That's exactly right. A nice little tube.

Hi Dady

Thank you for your information. For me, audio is never-ending the way, so it's hard to go to heaven.

30cm x 30cm pre amplifier, direct coupled #27 tubes. Selector switch and volume control in progress.

An externally hosted image should be here but it was not working when we last tested it.

WOW! That's neat and sweet!

This is my simple SE 12ax7/EL84 amp. I like the Edcor OPTs. They look vintage.

Hi Tipetu,can you post the circuit ? I would like to make one,thanks.

Thanong,

The Tubelab Simple SE or SSE is a design done by George Anderson aka Tubelab. Tubelab Home. You can get the circuit design at his site, or opt for the PCBs he also has.

Tipetu,

Looks nice - I am thinking of something along similar aesthetic for a Tubelab PP project.

 

[mhouston]

Hey looks good. I would have put the bare frame choke in a small enclosure if it didn't fit below. And I would like to see the schematic too.

I think is a challenge design, the complete article the circuit and the linearity choose by another Dutch contributor, I never saw such myriad of people so productive like the Dutch.
The electronics is very well distribution and soldered also the carpentry finish is fine.
Its looks like zen one device for use like mini table for feel accompanied with valves and chamber music in winter time. Or can use for play chess with a tube lover.
Original preamp Señor!

Some guy at DIYtube has come up with boards for a simple EL84SE-amp. Looks very good and enough simple for anyone: diytube.com :: View Forum - budgie se

It`s as simple as it car get. Although I had to put over 300µF in the power supply in order to get rid of the ugly 100hz hum. Now I can barely hear it when I put my ear 1 inch from the speaker. It`s ultraliear. These transformers have a 40% tap. Anybody tried using 50w resistors in the power supply section? My opinion is that resistors are much MUCH better than chokes..
