A new A30 has started to sing!

Please see the pics of my newly build A30. Beside a faulty ground resistor all was singing from the first minute

Hi Tarasque, congrats on the amp. Nice work. Thats a pretty neat heatsink arrangement.

Very nice job.

hi tarasque

clever design with inside heatsink and outside amp and supply
but i hope there is a free big hole underside for airflow
and maybe big stand off foot for airflow would be a good thing

tell me more about your power supply transfo + cap

bye I m sure you will be happy with A30 like me with A3

Very nice setup. I may have to steal that idea in the future

Nice Design Concept. Looks really impressive. I like the wood side panels. Normaly i'm not a fan of wood on any audio ( component's ) but that added a really nice touch.

Good job..

I'm using parallel windings of 22-0-22V (bigger xformers would not fit in the space I had left on either side of the heatsink.

The caps are 6800/50V Nippons, 24 pieces per channel.

Yes, you are right...There is a tunnel under the heatsinks for the airflow and sufficiently high feet.

The design was actually dicted by the parts I had in my shop. I was determined not to buy expensive parts like xformers, heatsinks and power caps. So I fiddled around with the existing parts and finally came up with this design.

Congratulation Tarasque, very nice job!

Did you measure the heat-sinks temp?

A30 is a lovely amp, I still dont believe my ears...
