I'd like to have the anti thump feature, I think you need a separate supply for that.

Why degrade what is a superb-sounding amplifier by using just the one SLB PS?
Great question, would a stereo build of this amplifier with a single transformer and slb power supply significantly degrade the sound? I’d love to hear more opinions on this as I plan my build!
Maybe “degrade” is too aggressive of a description.
Having built a few amps, the dual mono power supply builds have the quietest background and slightly better stereo imaging in my subjective opinion.
You can build a Fantastic AN with a single supply! But, if you have the extra $$$ and chassis space to fit the dual supply it’s something to think about.
Or….
Initially build with a single supply keeping in mind the thought of “upgrading” later to dual mono supply.

Thanks for the info @Vunce, very helpful.
Would two of the transformer below work with the R2R rectifier boards? I imagine I would need the extra winding for both channels… I didn’t see a 300VA 24v with the extra secondaries.

Yes, dual mono is recommended for lowest noise floor and getting it hum-free.
All the latest amplifiers that I've built are dual mono.
Learned it the hard way: an amplifier that I had build with a shared transformer had an annoying hum,
tried to get rid of the hum, didn't succeed, until I finally made dual transformers PS and it became hum-free 🙂

I read through this last year while building an amp, really a great wealth of information here in wiring an amplifier for zero noise. In particular the last section with practical tips and routing the audio input wires for reduced ground loop area. I found it very helpful.

Hello all, quick question on resistor choice for R124, R126, R143. They were spec'd as Carbon comp 1w. I read in posts 3074, 3075 that @Vunce recommended carbon film since the carbon comp were out of stock at mouser. The recommended parts in that post are 1/4w. It looks like the carbon comp were spec'd at 1w. Will the 1/4w work in this position? Any help greatly appreciated. Thanks!
Hello,
-R124-R126 carbon film-1W
-R143 metal film-1W
