GC with lab supply

Eric Weitzman · 4th March 2005, 02:13 AM

Does anybody have any experiences running a GC off of a lab supply? I'm considering building my first GC, using a high quality 2.5A +/-30V power supply instead of building a dedicated supply. Seems like this might be just enough to get 40W output from an LM3875 into 8 ohms.

I'd imagine a lab supply being a very good one, low noise. But 2.5A gets you more like ~20W per channel (if you use one supply for 2 ch. GC). Then again it may be well enough depending on speakers.
