Hi Cristi,

To bad, the 3020 is overkill for me I guess. I will source the other toroids. Suppose you don't sell them (or do you?? and what price)

Cheers

Peter

u can use TA3020 also for moderate power, having a bigger amplifier gives u the reserve, no need to listen at maximum.
i can sell toroids also, but i am affraid that the shipping cost will descurage the potential customers for them, a 500 W toroid which cost about 100 usd, can easily cost 100 usd shipping. i design some SMPS for the amps, which are more lighter and compact.

I am also interested in SMPS for DA-1. I have been looking for a power supply for this amp module but can't find one suitable

I have my TA3020 on the test bench at this moment. I'm running it on a 30-0-30v Toroidal with 4 x 10000uF, giving around 43v. Iv'e been running it for a couple of hours with 50w 4ohm load resistors and it sounds fine.

i will release SMPS power supply for DA-1 and TA3020 after chinese new year, hopefully in about one month, to have time for complete tests also. now i'm busy with some bigger projects which have short deadline.

I'm not in a hurry, I can wait. Do you have anymore details though? For example will the SMPS have any secondary voltages for powering things like preamps? a +/- 15v 500mA set of rails would be nice. Also, dimensions would be good to know, will it fit inside a 19" 2RU standard enclosure? etc...
