Hi Larry,
Last night I completed wedging an Antek AN3230 into a Toshiba SC-
665 power amp. Perfect but tight fit. Original power check put it at
68wpc both at 8 Ohm and 70wpc both at 4 Ohm. Obviously the original
toroidal was current starved. The rail voltages would drop
tremendously with applied loads. The Antek put it at 65wpc both at 8
Ohm and 95wpc both at 4 Ohm. Much better regulation and current
delivery. If I could do it over, but I won't, I'd have used the
AN3232 to get a bit more power. Cost? $36 + $10 USPS priority. I also
had to add a 12.6vac, 300ma R.S. transformer and a dropping diode to
keep the meters lit.
BTW, I'm curious....how did you like your sparrow feed Sony?
Ain't this stuff fun?
