Default p3a up and running :)

So, finally got the right size to3p style insulators and heat paste and one channel is up and running w/o any smoke so far

DC voltage on output is at 16.5 millivolts, much better than previous attempt at 36 Volts . This is with a load and input connected

I am crossing my fingers that it will stay that way w/o blowing up.
I am using On Semi mjl 193/194 pair. Rail voltage is at 36-37 volts.

If it doesn't let any magic smoke out, I will connect it to my diy speakers and see how well it sounds Don't really want to take my chances just yet.

Woohoo.

Hello Vivek,

I will post some pictures soon. Right now its just heatinks with pcboards mounted to them, and wires going to the power supply etc.

0 humm even with my ear next to the speakers, after about 2 hours of running it "idles" with 16 millivolts dc on output.

Hello Hugh!

This weekend I will try and do some listening and post my impressions. I am not really up on all the terms that magazines and professional reviewers use though.

I do most of my listening in near field, or on my headphones. I don't really have any hi-end source or pre amp equipment, maybe i'll connect my pc m-audio 2496 card directly to the amplifier and use it along with a dvd drive for the source. My other source is technics sl1200 mk2s but w/o any "reference" quality vinyl.

It would be nice to compare it to amp like Aksa on same set of speakers. So, maybe Santa will bring me Aksa to play with

Jean.

Jean,

Perhaps with little knowledge of the words and phrases used in stereo mags, you might come up with a true and accurate description of the sound..........

You can always trip along to George or Dan in Sacto and take your new creation with you - they would be delighted to compare!

By coincidence, just today I despatched two more 55W AKSAs to Dan.

Cheers,

Hugh

I never thought that chassis would be such a pain in the rear. I am trying to fit everything in and my 500va tranny is almost too big. Now I am thinking about getting a 330va just so I can fit it better.

Hugh,

can 25-0-25 be used with Aksa 100 kit ?

Default getting there :)

Here is a picture of a case which is almost finished now. I bought four matching heatsinks on ebay, and currenly only two are being used. I plan on adding two more channels to this chassis.
