It is pleasant to see beside a native lamp from USSRFranz G said:Thanks Greg!
It will be interesting to see, if the inspirations will lead to another very small tube buffered amps.
An externally hosted image should be here but it was not working when we last tested it.
Just to illustrate the size

... we don't sleep, just a little delay, because I had to build and enjoy my latest phonoclone
Here, this is an actual picture from my workbench: Analyzing the circuit again, measure the enclosure, holes etc. to finish the documentation.
Coming very soon in this theater.

/Edit: BTW, this little amp was working for more than half a year in a friends apartement. And this friend is very unhappy and unpatiently now, as he has to use his Sony surround system

I just added an updated excel sheet, containing the parts-numbering as printed on the psu-pcb.
The parts for the amps board are not numbered, but printed by their value on the boards.
Digi: did you draw any schematics in the meantime? We never had a schematic from the psu, we just worked with the print

gemby said:Digi, is it still posible to order boards? Any other payment method except paypal?
drop me a mail for service
I like pp,it is fast and easy.west union or cash order is accepted at the same time.
Evilsizer said:damn... i havent seen this thread for a while... maybe we can hope they have some extra boards.
We will start a main components group purchase(enclosure,rs232 lockable,relay,alps16..etc).
if there are enough interest,I will make round 2 pcb set gp.

Hi Zang, i just dropped you an email, btw, i am interested for buying kit, or main komponets group by, whatever....what will kit include? It will be very nice if it will include tube, pot, IC, socket, enclosure.....it will be perfect

Round 2? I was the first one to request a set and I still don't have a set..
Did I miss something?
I'm not upset, just VERY curious to what could have happened.
