Hello, please for your help.
I have 2 tranformers with 2X22/300VA.
I want to power the BA-3 amplifier .
The psu is the diystore Universal Power Supply.
How can i connect the two tranformers ?
Thank you in advance

The answer is simple. Wire both transformers (observe polarity with a dmm to find double voltage beteen extremes). Wire this junction to your ground potential (center of both capacitors). Thus both extremes to the AC point of bridge diode (made at hand with 4 diodes or get it done in a single package). Thus positive of diode(s) to positive of top electrolytics. The same with negative diodes to negative bottom lytic.
Primaries, according to your voltage and the primary voltages of them. If both has the same voltage as your line, borh pri are in parallel (observe polarity again aditive at secondary). If each are half voltage respect to line, both pri in series (same note as above).

You have omitted the rectifier diodes from your schematic.
Why 600VA?
Bear in mind if you are burning so much power, this amplifier will also heat your room, empty your wallet with energy bill and melt the ice caps.
If this is for stereo and you need so much power, build 2 separate power supplies, 1 per channel.
