You mean a part number for it Lee? 621-KBP206G

On the assembly I have I actually used 583-MDA100G

At retail, just the power supplies will be 2K...

OK, I've been researching DC ammeters and voltmeters. wanna put one of each on each power supply. Simpson makes some nice 3-1/2" panel meters. Whadda ya think Joe? The 523 series---15046, and 15035..

Don't you want to go retro with those cool round analog meters??

 

[laatsch55]

They still make em??

Direct hookup 50 amps and below, no external shunt, VERY COOL....

The secondary winding won;t do any good till the toroids are on....duh..... so we need a xformer to supply control voltage to the board....duh.....whats the specs on the control transformer Joe?

They were too high voltage anyway Lee.

Thanks Joe, at least this way a guy can use a couple small switches...one for AC to the board then another to trigger....or a DPDT to do both......can't think of a reason the trigger should be separate from the board ....can you?

No need and there is a build option on the board Lee so you do not need the trigger input.

If you install R21, the sequence will start when you apply power to the tiny AC transformer I gave you the part number for.

Ah.....very slick Joe..thanks

So your AC power switch is just turning on that tiny transformer. The heavy duty relays do the rest. AC is always on to the relays.

WOW.... WOW..... This is going to be something !!!!!!!

Yep, sure opens up possibilities on the switch selection. I like the round meters too, gonna go with those...

If it all works Kev....in theory it should all work, but you know how that goes, I expect a wrinkle or two, but nothin Joe can't figure out...

I'm just wondering if we're building an amp or a substation here... LOL

 

[laatsch55]

A big amp starts with a substation...was at the shop awhile ago, had to whittle on some BABB's

Man, I was just thinking the same thing and also wondering what kind of speakers are going to be able to handle these monsters at full throttle

 

[laatsch55]

None I know of for continuous duty but a lot of headroom. I'm sure there are some subs out there...
