Maxhawk is in process of forming a GB for his softswitch. It looks pretty good.

Soft switch version 2 anyone?

Impressive design.... yes.... but why so redicoulously complicated! Its much more complicated than many of the amplifiers we are all building ..... How come? Especially when a $2.00 current limiter will do the same thing and work just as reliable.... ?

Shown is the soft start v. Full Options GLXTDI deLUxe with a Supercharged Hemi V8 and sports suspension.

Not the complete schematic has to be build. Functions you don't need can be left out or bypassed.

I would choose the Economy version but keep the Supercharged Hemi V8

I've built the PCB (4 of them in fact) and it tested OK.

There is only a small change on the PCB. One of the AC power relays pin had to be insulated, and was not. Corrected the PCB, now version 1.01.

Corrected also a typo error on the schematic, U2 is 74LS04 and not 74LS14, it was ok in the parts list. Sorry for these errors.

Except for that, the PCB is working like a charm

Here the corrected schematic
