Hi all 🙂
After successfully completing excellent SA2014 from @astx , I decided to build the SA2015 V-Mosfet (4x SA2015 in one box). I want to build this amplifier for Bi-Amp wiring and compare with single amp wiring (SA2014).
This 4x SA2015 V-Mos will be housed in a single 5U/400mm box from modushop. The feeding of these 4 modules will be handled by 2 massive 500VA toroidal transformers from Toroidy_pl. Each module will have a separate power supply (4x 15.000 uF Nichicon).
Original thread ASTX: https://www.diyaudio.com/community/...ance-class-ab-power-amp-200w8r-400w4r.235194/
SA2015, PSU , transistors --- (all from astx)
Softstart (incl DC protect)
SSR3 speaker protect
If anyone would also like these protections they can join the ongoing GB.
Ground Loop
* All input and output connectors will be of premium quality as well as the internal cabling, ...probably from SUPRA.

Friends I am working with this project and also on a discrete DHA2 preamp from a Slovak designer as well as on a discrete MM preamp so progress is small.
Ready softstart, tested and functional:
Ready 2x PSU, tested and functional:
I have already received an auxiliary heatsink plate 10mm thick pre-drilled and ready for two channels:
Over these holidays I hope to get to finish SA2015, ...I have 3 big boxes of mouser 🙄
