2oz Cu plate on the OPS pwb's?
Happy soldering, good luck on power up test

Cheers
2oz Cu on 200W CFA and PS regulator boards. There are screening masks on high current lines where is possible to solder additional current reinforcements (wire).

Two, two-channel amps are needed for Bi-Amp'ed JBL M2 system.

Default CFA amp progress

I've just finished one side with 3 amps for my active system. Still missing analog VU-meter. So far sound is fantastic.

This is 200W amp on its way to the finish state. The photos show the bias setting. I used temporary power cabling to have one by one channel out of the box during bias setting and later fix it to the box sides.

PS. Mario that looks beautiful.

Damir, I adjusted bias on the same way, out of the box with longer power supply cables.
