I wonder if a moderator can help you replace the file in that post or at least add a note in that post to refer to a corrected file. I spent a few hours trying to get the amp working properly and somehow I got it to play but not well enough so it ended up on a shelf. I have replaced the diode but didn't have time to test. I will get to it later today.

Blessings, Terry
 
Hi all.
I'm trying to make psu of sr50
but It's my first time making amp
and there's something I need your help

1. i see two 2SC5200 in schematic
but there's only one in pcb
is this pcb wrong? or is this ok?

2. and.. what is that 2k2 resistor tie to MPSA42//MPSA92 ?
just simple resistor or something else?
i don't know what to buy..

3. my hometown use 220v AC,
what transformer i should buy?
is this ? ( 220v AC primary // 2x40v AC secondary )

4. right side of trans, 4 diode making diamond
and the number 35A/400V
what is this?

Start with some simple like AX6 for your first amp,

Some picture of my SR100F, singing very good, relaxing....
Offset can be set to zero with trimpot, testing only with 25 mA bias because heatsink is too small.
