@Keantoken: I have a doubt about Vbe(Q4) and Veb(Q3). One left channel I measured Veb(Q4) = 0.6649, Veb(Q3) = 0.6017. So after calculating it becomes 60.0632. Similarly right channel is 60.0673. Is this the calculated value for R1 (=R2)?

Yes, that is correct. Notice that is just a 7% difference from the original value of 56.

Thanks!

I did the usual checks and adjustments (0.012 - 0.014 mV DC offset). This time there is absolutely no hum or hiss. I'll need some burn in as I'm experimenting with a thicker solid core internal wiring (20 gauge, Teflon insulation).

Project, can you share the Sprint-Layout file for this power supply?

What style or brand of transformer fits on the board?

Thanks...

Hello ammel68!

I used this transformer.
https://www.reichelt.de/Transformers...tnr&OFFSET=500

For the sprint layout file is importing gerber because originally the layout has been designed with DesignSpark.

Hello Project16,

Thank you for the zip file!

I'll have to search around and see if I can find a suitable transformer from Mouser or some other seller over here.

Can you list the exact parts you used? Is this before trimming?
