why - as I said - you already have AVC and few Toshiba JFets........ and schematics are above , of which you can use reg part , while making complementary JFet buffer
some veroboard , and money best invested in some LPs

True, but I like your execution with input selector and volume selection relays 🙂 and for that matter I already have a nice Aikido linestage 🙂

15 mA per channel? 150 is quite a donut : ), in your picture i´d assume a 8cm x 4 cm Trafo.

EDIT: arrr not 150 VA : )

I'll tell you anything about dimensions , in few days
now I can't be sure , while out of workshop

I just got mine a few days ago. Mine measures 89mm (3.5 in) including the screw heads on both sides holding the plastic top and bottom pieces together.
This AVC is definitely the best looking volume control in the history of mankind. It would be a pity to hide it in your espresso maker. 🙂

thank you for your kind words
I really really really invested all my heart in that (I hate word -> ) project
And it shows! Exceptional pre-amp/tone control; the only way they ought to be made if nothing but the best sound will do🙂 Well done, congratulations, bravo majstore.
they're simply better parts , for audio purposes
while 2SK2145 are made for "Audio Frequency Low Noise Amplifier Applications" , J111 etc. are "chopper" parts
see datasheet : https://www.google.com/url?sa=t&rct...Name=2SK2145&usg=AOvVaw3-QiMZoACjq-xrd1YMVMdk

how do you match the 2 jfets inside one chip?
Are there many differences or the 2 jfet on the same chip are almost matched every time?

1. they have common source , so certainly being matched good enough
2. I'm treating one tiny bugger as one JFet ....... so just taking care of triplets matching

@ZM, do you have a dealer for the 2x30Vct Trafo? Space is little in my case, but i didn´t found dealer for 2x30vct. Two of the donuts woud be too big, and i´d go for one 30Vct otherwise and leave the separation to the shunts : )

what you mean by - do you have a dealer ?
you mean , my local one ?
I have , several ,pretty much always ordering custom (regular production being in industrial range of values) ...... though , I can't tell are they willing to send out of country
send me an email in few days , I'll check in a meantime what can be done
in any case , shunts will do what's expected with rails , but once you connect GNDs of two channels , there is a headache on the horizon
so , leave them separated , on any price ....
