The original poster wants a stereo 60 watts per channel amplifier.The power transformer he wants to use has a high voltage winding rated at 600-0-600 and 200ma.
With a cap input filter he would have too much voltage and too little current.
Cap input filters gives you 1X of the rated current of the winding and 1.4X voltage.
Choke input filters give you 1.45x the rated current of the winding and .9X voltage and much better voltage regulation*.
*To get 60 watts it's likely to be Class A/B circuit and the current draw will vary greatly.

- The power transformer {60 watts 2 channel} is enough {barely} more call for voltage regulation over electro- - Cleantimestream 18:39:43 03/19/12 (0)
