Is cool Dx Super A is a design from Carlos destroyer x you should try out sounds really good 😀

in this link you will find more information about this new type of amplifier.

Well I call it Super A because that is the name the schematic designer use, so I will keep calling it Dx Super A the layout was design entirely in Puerto Rico with the help from destroyer x was not easy at all but was accomplish. 😛

I've seen some of your and Carlos' work already (power supply), and liked that also.

I was wondering about the flat heatsink, but maybe Puerto Rico is much cooler than I thought... 😀 "Super A" and "Supercharger" sounds like more power than I can afford, 😉

This one only cost about $12:

Losten13,
WOW...fantastic...looks like the equipment from Flash Gordon movie

Where did you get that nice heat sink? 🙂

This one came from a company in Michigan, Heatsink USA. I think they advertise somewhere in this forum. Their pricing and estimated thermal capacity seems very honest to me. I compared their C/W ratings with some similar "finished" products (which I knew to be not-so-accurate) before I ordered.

The one you see in the pic above is 10x4 inches with 1" fins... overkill for what I am building now, but I will be using it as the side of my chassis, similar to some of the commercial chassis you see in the DIY store here.

10.000" - HeatsinkUSA, LLC Store

The heat sinks are not "finished", meaning not anodized or painted etc., and you may have to use a little sand paper or a file on the edges, because they come cut in the size you order directly from the shop. However, the side that matters is nice and flat & very clean (I had a friend measure it in a machine shop). Much better than "mill finish" aluminum plate.

Here is another picture of a different chassis prototype with the same heatsink, after drilling and machining, but before surface finishing (not complete, but I think you can see the important parts):

Hello,

my Aleph3 replica gets a support from my new preamp now... 😀
also a Pass design features a single stage MOSFET class A amplification.
It is integrated with a 128-steps potentiometer (based on a relay switching).
I also integrated a TDA1541A S1 NOS DAC with discrete OPAmps as output stage.
(...for my Micromega DUO CD2 transport).
But have a look for yourself...
Best regards

well poluchilos.that circuit preamplifier and power amplifier?

Very nicely done! That Aleph is a very neat and tight fit!

Hello valvesound,

here are some inner details of the aleph (of cause it's very tight...)
I build it as a double mono construction with two transformers and two power boards.
I also integrated two separate soft start with separate speaker protection.
you see, every space in the amplifier is well filled... 😀

You did a good job packing everything in there. I like those heat-sinks but would not have used them because I would not have envisaged all that can be packed in such a small space. Well done entenschreck!

 

[entenschreck]

The small place was a compromise because of the huge heatsinks. 😀
The task setting was an amplifier not larger than the standard size, but with an effective cooling.
And it works very well... temperature rises never over 55°C (131°F), not like the original 🙄

Working on the new full featured preamp - but still months to go. This is a big one mechanically and electrically 😉

Hat's off and congratulations to entenschreck for a truly formidable build. I hope it sounds as good as it looks and I am quite sure it does!

 

[entenschreck]

Many thanks for the nice comments...

I still have a (design-) problem... i got new solid chassis feets and volume knobs.
Which one of the volume knobs would you prefer?
I'm really undecided...😕
