I've checked out many amplifier designs, and especially the PSU designs. But there's a big difference in the recommendation for the power of the transformer (sometimes it varies about 2 or 3 times for the same output power).
So, I would like to ask you what class AB amplifier (stereo, maybe 4 amps bridged) (?? watts) I can build with 8 transformers of 120 VA (1x30~34V). The transformers can be placed in parallel without any problem (because that's what I'm doing right now). The amount of capacity is no problem...
The load will be an 8 ohm speaker. I normal conditions the amp would play 2 x 100W (rms) into 8 ohm load, but what is the limit I can push the amp to (without blowing any transformer) when we need some more power? (in this case quality of sound isn't that important)
I would like to protect those transformers against too high currents with fuses, what fuses should I use there the max. current in the secondary winding is 4A??
HB.
