Finished compact p3a amp/chassis today, few pictures.

Jean · 19th March 2005, 11:26 PM

Got myself a table saw finally, and with the right blade cutting aluminum is so easy ! I had two extra p3a boards, so I decided to make a compact case for them. Heatsinks I got from a local electronics shop, they only had 4 and they were already pre drilled/tapped for the most part.

PSU is a single 250va avel dual 25volt transformer, bridge and 12500 uf caps from ApexJr.

For better view, shot of internals. I pulled the AC line jack from a broken psu, it's 6amp rated with emi filter.

Spare rca and speaker posts from partsexpress.

Bare aluminum finish, it was covered in stick-on film that I pulled off once I was done with drilling and cutting.

Looks very nice!

What exactly are the dimensions?

Hi, it's 10.5" W by 6.75" H by 7.5" D . Here is a shot of the internals, I tried to keep everything as clean and short as possible.

I like it. That's really professional looking and very compact.

Did you make your bidge out of rectifiers from computer power supplies?

Thanks. I used BrianGT's GainClone bridge board and MSR or MUR diodes. The AC jack/filter was from a 300watt psu.
