FS 6c33 SE Triode monoblocks
I have two kits for 6c33 monoblocks, one is being tested right now, and one wainting for some parts.
I will sell the first set, so i can finish the second one and also a finish pair of speakers for them (HORNS!!!).

The parts are all good quality
Solid wood frame
2mm Steel, powder coated
OPT Wounded by the best romanian winder, 18-60.000 hz bandwidth
Toroidal power transformer
Teflon/Oil capacitors
Cliff output connectors(i think the RCA-s are Cliff also)

I can make a package with an ES9023 DAC, if anyone interested :D.

The photo is old, but i will come back with more after i pay a visit to the engineer who asambled it. :D

I will come back with all the details, photos, schematics, osciloscope shots and price(have to add all the costs first)

Santa was nice this year!
Schematic :
Amazing low end response for a SE tube amp, on regular towers/bookshelfs(IQ, MBQuart, Vienna Acoustics)....
Neutral sound, no HUMM, even at 10 cm from the speakers
Screws have to be changed, and i have to fit the ampermeter and they are ready for sale. That will be next year.
The price is 1700E for one pair of monoblocks and i can offer the DAC/PREAMPLIFIER as a bonus.

PS: Shipping options will be discussed on PM.

Every photo shows different "configurations" of the amp - transformers rearranged, VU meter seems to be gone. Also was there a rectifier tube that was removed?

Hello there!

First photo was made a few months ago. No components inside the boxes at that time, just a moch up to see that everything fits. No tube rectification.
The Vu is actually an ampermeter and it will be in it's place next year, as soon as i recive the stainless steel ornaments.

I will make a group buy next year for a stereo version.
This valve is amazing! Everybody should have it!

could you please give an expression of how they sound? I've heard 6C33 sounds like SS :eek: but I don't get them serious as someone I trust his opinions (Roomy the cat) use only 6C33 amps with his horn speaker :o
