Hello,
I was considering using this supply to drive a pair of ZV9 amps. Is this a good way to go? What do you all think of it. It costs just a little more than 2 toroidal transformers from Toroid.com

The specs are good. One thing that bothers me is that it has a fan. Don't know how noisy it might be. Another concern is, I do not know how many thousand micro farads of capacitors I can use on the supply before the supply refuses to come on.
Dual adjustable outputs: 0-50V and 0-5A
Line regulation: CV <= 0.01% + 2 mV, CC <= 0.2% + 2 mA
Load Regulation: CV <= 0.01% + 3mV, CC <= 0.2% + 3 mA
Ripple noise: CV <= 0.5 mV RMS, CC <= 3 mA RMS
I know, I should be building one, but I am cheating
Thanks,
Dinesh

Hi everybody,
64 views and still no response?
Obviously there are not too many people who have built a ZEN, much less use a bench supply and nobody used a Mastech?
Let me ask this slightly differently, anybody used a Mastech supply for any purpose, if so what do you think of it? Better still have you used it on an Amp?
Thanks,
DInesh

Dinesh, here is one response: I would never use a thing like that.64 views and still no response?
A simple supply consisting of "trafo-rectifier-smoothing caps" is perfectly suited to drive a poweramp. Its very fast and delivers the needed current on demand.
That Lab supply might be good enough for testing purposes though
