A nice linear PSU for you try with a tacking feature.

Possibly because 50W class A is a lot of heat to handle, may have been more interest in the 10-20 Watt range, I put my 20W pp class A to bed for summer because of heat and it just feels wrong to use it, single ended 50W, yikes!.
Try 300W Mono Blocks idle power each 1800W

I remember seeing those at live’94 at Heathrow. I think they got stolen the next day I wondered a) how did they move them without anyone noticing b) who would they sell them to?
Firtly,
Max dissipation depend on heatsink
Max current and voltage drop will give the max heat you will need to get rid of, total max is 400W thus 200W/side.
Now you will have to include the ripple voltage in your calcs.
i.e. as a rough guide at 50Hz main 10,000uF total is 1V ripple for 1Amp therefore for 2A it would be 2V.
so with 30,000uF at 3A it would be 1V ripple.
Total absolute current is about 40A at that you can say the max voltage drop is for 30,000uF 5V now allow for ripple.
OK to make simple I will do a XL chart and dump it up for you all.
Phew and I am busy today building amps, he he not peace for the evil.
