Bryston 4B SST clone

I'd pay more attention to output transistor matching rather than using 6 band resistors

I'll also pay attention to transistors. Thank you

 

[Sensation45]

I have 6 band resistors available for a long time.

Is it okay if I use 50v zener diodes instead of d1 and d2 zener diodes?

 

[amplidude]

I'm not sure, I'm on a tablet away from home, it's long time ago I build it, what's does the bom list say? 33v?

D1 and d2 diode 1n4148 schematic

D1 and D2 are small signal silicon diodes, not zener diodes.

the lastest available version

4B v5.0 just add two 100n cap

Does anyone need such a *.LAY? I'll just say right away that I didn't launch it in the hardware, so you need to check everything - double-check.

The 1n4148 is such a cheap part, 100 for a few bucks, no hassle, I'd stick with the intended, otherwise compare spec sheets, by eye they look similar apart from voltage

thank you I have 1s955 75 v 200ma small signal diodes I use them

Here's a chart of transistor logos, might help

No match in the chart 🙁

Well spotted...
