That would be B3
It would be cool to kick in 10db of gain with the flick of a switch or leave it switched off for a unity gain buffer.

I saw that, and it spurred me into action.

You mean something like this
Buffer/gain preamp..

Nice Job.
I have a feeling Papa can add couple of parts to the B1 to give it 10 db of gain on demand.

Smart thinking.
What kind of attenuator you got there. Looks spiffy.

Thanks! The attenuator is a goldplated Elma, with finely calculated attenuation curve...
labjr said:Could someone comment on which transistors need to be matched on the F5 boards.?
Do Q1 and Q2 need to be matched to each other? Do they also need to be matched to Q1 and Q2 of the other channel?
If you intend to build a F5, you can just as well read this:
F5 article

I've read the article. It doesn't say which parts need to be matched.

hello cviller!! first off thank you for your efforts!! can you e-mail with payment info 4pcb +2psu shipped paypal.i am new here here and cannot e-mail here yet. also i am building aleph 3 can i use the same toroidal on both then i can buy from same source! if you can let me know the specs.i have been told a 19-0-19 600va works on both.thanks in advance peter

Papa uses 2x18V, but I think you'll be alright with 2x19V. 600VA will be plenty for a stereo amp.
He doesn't use a a 600 VA, does he?
