SE Amp. 2*mono .Tube 6C15P, 300B .no caps, no coil,
Do you have the schematic? very nice clean build by the way. Good work.
Cool what the schematic look like ?Maybe a little late, but finished this a few months ago.
6528A Schematic
Not complicated. Output 60 watts a channel 0 db 20 Cy to 20 K Cy.

All housed in a Twinnings timber Tea Box: Bitumanised Al foil controls enclosure resonance and Russian paper in oil caps link the modulated HT to the real world. Silver solder is used throughout. Heavy duty high grade gold plated RCAs grace the back and all is powered by a 24V 1A plug pack. There are two switchable inputs, alps blue velvet pot and black chromed solid brass knob.
Power supply and amp reside on a single piece of vero (strip) board. No PCB or shielded wire is used. Any 12A?? tube can be inserted with no components changes. Sound is big, bold and fast with a Mullard 12AX7 in place.

PSE + speaker RK0
Incredible, what is this amazing devices? Please publish the plans.
I wanna them!
Audionote M7 modified preamplifier
Hi,
I build a phono tube preamp modified Audionote M7. I used 12AY7 and 6N6P tubes. Coupling caps are Russian nos teflon, output caps are Russian nos PIO, RIAA caps are Russian nos silver-mica, all resistors are metal-film.

2 speaker - black
2 crossover (granite - black)
2 monoblok - tube PSE, kt 88, ecc 82, ecc83
1 preamp - tube SN7, ecc82, ecc83, RIAA
(all my design and construction)
Whole is not easy to do (except that it is patented). For example, casing has about a thousand laser-cut parts.
Have a nice day

So exotic amp and speakers, Enjoy but please if is possible more details of the technical and the finish that is actually so beautiful.
Have you a nice day too.

Thank you.
Well, as I will have more time write.

Just to point out - it looks like the bridge for the bias supply is reversed. It should be generating a negative supply but the diodes in the bridge as drawn would give a positive supply.
Parafeed SE 6550 / KT100 (EL156)
Finally found a moment to post my current amps.
They are two parafeed amps with external PSUs.
The amps have been running on 6550s until this week. Now I'm trying some old Valve Art KT100 (actually an EL156 with octal base).
Still not done with these amps, as there is a low level hum in one of the units. Unfortunately my little Russian scope decided it's time for its retirement, so I can't pinpoint the source of the hum. If I can believe my DMM it is only on the OT secondary, not its primary.
The PSUs deliver several filament voltages and three different HTs : 300V - 400V (regulated), 370V & 1kV. This way I can use it for more than one amp. Now I have just the two parafeed monoblocks, but I'm building a SE 6L6GC and a SE 813 guitar amp that will be fed from these PSUs as well .
Eventually two parafeed QB2/250 (euro 813) amps will see the light. Or better: bring light to the room

Oh and that thingy with the silly sunshade is a valve audio device too. Not finished yet....
Does it spin?
