OLD THREAD Hi-end phono preamplifier by Andrea Ciuffoli - Page 40

I'm very interested in any PCB boards for the variations on the D3a and C3m and the new preamp and any masterfull powersupplies.
I can build it myself if I have a parts list and a well made PCB board or even just a list of parts (or buy parts markup 25 percent) and pictures (no insturections-unless really hard) of maybe 6 stages as you build so you can compare your progress to the original.
Please post me if boards are available!!!!!ASAP!

Does anyone know if this is in the works or should I proceed with trying to build a D3a or the C3M amp point to point with a lot of the values missing? I'd much rather have
a pcb with easier instructions due to language barrier.
Thanks

Please advise how I should purchase the PHONO-ASH (Phono D3A) board and the SSHV power supply board to build this D3A phono stage amplifier.

I have a mate [here in China] that has building custom Class A valve equipment [amps, pre-amps, etc] for >15 years.

He can do custom work[OTs, Chassis, PCBs, complete , and provide parts.

His last customer bought a 30W RMS Stereo Amp [Russian valves] with silver wire wound OTs!

Have photos on FLICKR and price list for Russian [and Chinese OEM] valves...........
