in order to use cheaper and easier to find transistors for Q7 and Q9.
KSC1381/KSC3503, cost pennies at Mouser's.
Thanks for the replies, everybody. But, I guess I didn't ask the right question. I know what the current is and how to decrease it. The question should be: How would I determine the optimum current and what is the minimum current without sacrificing too much sound quality? Add on: what are the best semis to use for optimum/minimum current?
Feeding the input capacitance of the six output transistors with enough current is my biggest concern-I guess I should do it the hard way and try to use that calculus I supposedly learned. . .

Hi,🙂
this is my almost finished up: I must anodize with titanium color front and rear pannel and upper cover with black pain.
It sounds really fantastic: precision,extension, separation and force are present at a very high degree.
I have only a little problem with the vumeter: it is really difficult to stop it in the middle of the line: after tuned in that position it wander apparently without control returning slowly at the beginning of the scale or going with same speed at the end-scale.
Anyway a great great amp: with ugs a perfect marriage!
Thank you Cheff!🙂

Groovy, what a shagadelic stack of source resistors.

Hi 10Y, thats a great looking amp. Nice work. I may finish mine soon.
Thanks Luke for your kind words 🙂
Wish to see your realization soon.
Ciao,

Even with matching number of mounting holes in the V2, 24 times 7 times 2 still is a lot of holes to fill.

Spent about half an hour on soldering all those resistors 🙂

I had those boards and sold them - that's a very tough build. Congratulations, the amp looks great!

Thank you NYCone🙂
Have you tested yours ?
Did you have problems regarding vumeter setting?

I thought the build was too difficult, and sold them before building.
Nice job 10y, wish I had access to a metal workshop to build some nice art rather than my usual cardboard box
Then do a woody.
Front plates in wood can be (hand) painted to look like anything you desire ; Anodised aluminum, marble, granite,...ehh, wood.
And easy to repair, try fix a scratch on an anodised metalico.

sorry confused sold with to solder 😱
