What Power Suppy did you use?

The pre-amp uses the transformer as supplied by Yuan Jing and for the 3116 I'm using an Indeed 12V "brick", I have tried a couple of cheap generic bricks off ebay but they both produced so much noise they were worthless (for audio applications).

I have 2 of the Indeed pwr sup's now and can highly recommend them.

Thanks for the info...I'm partial to switching PS from Genssi, but you need a large enclosure and economics sometimes come into play.

They are DC, not AC . I use Sure boards, which are DC. Usually I use 36VDC 9A. Here is a link: http://www.amazon.com/Genssi-Regulated-Switching-Power-Supply/dp/B005CLCJA6

PG, love the retro-chic look to that!

thanks tf

I'm always on the look out for small boxes that can become amp cases.

my 2 cents
200W @4E has a flat response from 20hz to 20Khz with a slight peaking above 35khz ,it includes DC- protection ,clip pop removal , thermal + shortcircuit protection,signal presence and clip indicator with a option of interface with a VCA .
next attempt 1200W @2E

cheers

Nice little cast aluminum case found at the Goodwill. . Cheap Lario 30-pin adapter ($15 on Amazon) supports Internet radio with TuneIn Radio via AirLino android app, plus AirPlay and UPnP.

An externally hosted image should be here but it was not working when we last tested it.
