Selling linear power supply board that contains 4x6800uF 50V Nichicon Capacitors, Vishay 35A Rectifier Bridge with heatsink, LM317L / LM337L regulators for 15V out.
The board utilizes simple and straightforward design with two output voltages. PCB layout was optimized for high current flow for V+ and V- traces.
All components were sourced directly from the manufacturer or authorized distributors (TI, Mouser, Digi-Key).
Four 6,800uF Nichicon capacitors totaling in 27,200uF capacity
Up to 28V AC input voltage
Up to 40V DC output voltage
35A Vishay rectifier bridge with heatsink
16V regulated secondary voltage output based on LM317L and LM337L
Power LED connector with LED
Snubber capacitors for transformer secondary windings
Bourns 60V AC varistor for transformer secondary windings
Bleed resistor for main capacitors
Organic polymer capacitors for 16V regulated voltage output
High quality connectors accept 22 to 12 AWG wire
Board size 75mm x 100mm or 3’ x 4’
For LM3886 it is recommended to use an AC input voltage of 20V-22V to get 28V-30V out.
For TDA7293 it is recommended to use an AC input voltage of 25V to get 36V out.

I did not see any power resistors, so assuming the regulators are driven directly from output voltage keep in mind their maximum Vin rating (presumably 40 V).
Edit: just saw possible zeners, in that case never mind!
