Hi~
The comment I make about the 1.5kw amp ...was, as I said, for comparative purposes...
As, it would require the same voltage (77 VRMS) to drive 1.5kw into a 4 ohm load...
As 200 watts would be into a 30 ohm load... (77 VRMS)
On the line under that, I mentioned "there would a considerable surplus of current ..."
And I could remove some of the output transistors as to remove the current surplus...
As for using a transformer... thanks for the tip about making one...
However.... I have been advised that the kit amps I already have (based on 2sc5200 and 2sa1943) will prolly not handle 200 watts at 28 khz...
So I might as well start from the beginning.... and just build an amp that doesnt need an output trasformer...
Which is what Im currently doing... found a schematic online for an amp that will take +/- 125 VDC... (not the 117 from esp)...
Monday I will prolly pick up the parts for it...
Thanks,
Michael
