Your Mightiness,
I am about to order the parts and have some
questions 😀
Well, not that much questions
Many thanks in advance!
I am about to order the parts and have some
questions 😀- Zeners: is 500 mW okay?
- NTC 10R: dito, is 500 mW okay?
- What should be the value of C112, C113 and R140? (connencted to the rectifier bridge)
- What should be the value of the optional LoadR and when should it be used?
- R121 (and others) are 0R - just a wire?

- yes
-no, choose them by size - 10mm Dia , I believe you'll find them as "surge limiter"

-if you ave Quasimodo, you need to test your xformers; if not, omit them
-only in ase if you want to invoke much heavier load for buffer, thus invoking some higher 2nd ; say that things are starting to happen with values down from 4K3; but - you didn't go for IP because of sweetness...... so don't bother
-value of 0R means - either wire ( take care of isolation in some positions) or fancy resistors with one black stripe; reason why fancy resistors with one stripe exists - robots for parts populating ( industry) are much easier working with resistor shape than with shape of plain wire bridge
Dear ZM,
is it okay for the case too when I use the RC-unit (I'm planning to do so)?
Hi ZM,
before ordering the donuts (from Antek) just a quick check: could the audio-side donut also be 2x15v or is a 30vct a must?
Because the relais-side can use both.
Thanks!

rectifier arrangement is with CT
and you're big boy enough, to connect 2x15V as 30Vct
trouble is when you have CT and you need separate .........
so, all good

Thanks, I know, and I have done it that way for most of the parts.
For the rest (and missing parts) a sligh bending of the parts legs right behind (below) the hole helps keep them in place 🙂

I'm preparing special iteration, common for Italian and Scandinavian market

Just kidding. Build looks lovely!!....where si****s means what? 🤔
maybe missed some posts, but what transformer(s) have you chosen? (Brand/type)?
That’s heritage right there!! Almost, only missing this 🙂I'm preparing special iteration, common for Italian and Scandinavian market

Thanks
Anteks, 1x 12v 10VA, 2x 15v 10VA, they are under way, but USPS needs about 3 weeks or so
