No, it's not tested just simulated.

Make a layout and I will test it. 😀

I will, but V10 first 🙂

Sure, layout?

I will test A10, so I can make a layout this weekend, ok?

Other problem: I have a few 6N1P, no ECC88 or 12AU7. Can I use the 6N1P to build a V10? And if possible, what changes are needed?

regards Olaf

I have used 6N1P in place of ECC88. It draws more current on the heater but the pinout is the same.

Please share the layout when you're ready.

Thanks, Terry

Hi Terry, ok.
I will make a layout for A10. Very nice project, I'm really curious to see how the amplifier compared to A9 sound.

A10 or V10, A10 use 2SK117 FET input.

I want to build both. 😀

You can use A10 pcb for test V10 with tube out of bord.

V10 needs a heater circuit for the tube. Am I correct in assuming it only uses half the tube?

Thanks, Terry

Yes, 6,3V to pins 4 and 5 of ECC88. Single tube (dual triode) can be use for stereo amp.

Sounds good. Maybe you can do a stereo preamp using one tube. That would be very interesting.

I do that long time ago.

Awesome! Is it for sharing?

Looks interesting. Pretty high voltage. I'll have to order some caps. I don't have any that high.

You can use 250V caps instead 400V.

VX120 is Tube/SS VFA amp, V10 and V12 is CFA.
