Hi Friends,
I have started on a path of building a DIY amp with TPA3255 board.
Board has been ordered.
Power through transformer 48v.
I have referred available information and posts by FMs on HFV and relevant post by FM @vizeta in particular.

Board: Ordered from Amazon Japan. Details were in Japanese. So posting this link in english.

I suppose a rectifier board would be needed for transformer. So I could find out this one.

VASP Electronics 10A 50V Max Power Supply Board for Audio Amplifiers & DIY Projects using 10A10 Diode & 2200uf capacitors https://www.amazon.in/dp/B07KSVCWBY...abc_KBRNYCYPBFEKEYND631E?_encoding=UTF8&psc=1

Should I go for any specific brand of transformer and rectifier board?

Hi. Thanks for the encouragement.
Mean well 48vx7.35A is in transit. Expected shortly. I have received 40V transformer. Will be checking the difference, if any which I can hear, with smps and using transformer too, just out of curiosity.

Update:
1. Amp board, cabinet, smps 12v, 5v, transformer 40-0-40, misc items received.
2. Meanwell Smps 48v & generic 24v shipped

I also have a 7498 board which needs 24v/36v dc.
Since the cabinet is large enough, planning to put both (3255& 7498) inside with separate power supplies.

Tpa3255 itself is great. But good two is a company
 
Purchase the Audiolab 6000A Integrated Amplifier at a special offer price.
