:thumbsup:

Meticulous attention has being paid, but to be expected from you going by earlier B1 build.

Looking forward to pics of finished amps!

Thanks denom, any input on finish is welcome.

Hi! Few questions!

Nice use of a combination of older electronic cabinets/Heatsinks/aluminium sheets! Correct me if I am wrong!

1) Details about the R-Core transformer for preamp and Torroid for the power? Any economical sources for the same?

2)Sound impressions and what speakers you are going to use them with.

3)Could you share some of the schematics/Project Pages?

Really impressive build!

Thanks

Thank you drphil,

You got it right. The commandments of DIY.

Transformers are sourced locally.

I have driven Dali Concept 1, Dynaudio audience 42W and the SQ is audiophile.

Schematic is from TDA7293 - STMicroelectronics

Thanks denom, any input on finish is welcome.

How 'bout a metallic auto paint finish to the cabinet & buffed heat sinks??? Should look very boutique & classy!
