This thread is for discussions about the new Speaker Turn-On Delay and DC Protector boards (V3). This is an updated version of the V2 boards, primarily to make them compatible with the 10x10 grid mounting pattern we've now standardized on so they can be easily mounted to Deluxe chassis baseplate, riser panels, front panels and/or heatsinks. Refer to the V2 discussion thread for additional information.

Relay spec says 5A @125VAC into a resistive load
However it also says 10A if the Normally Closed connection is not used (it isn't used on the Delay board).
so.....
625W theoretically but I won't be the brave soul who tries out the limit.
Spec of relay is here

This is the current schematic;
It will be on the site shortly
It pretty benign and can be used in applications other than the F5 and F5T.
U1.1 is ground and U1.2 is + supply

An externally hosted image should be here but it was not working when we last tested it.

So the 3.0 BOM has Q1,Q2,Q3,Q5,Q6 as 512-KSC945CGBU which are ECB according to http://www.fairchildsemi.com/ds/KS/KSC945.pdf but the board is made for EBC.
Some assembly photos -
Diodes first
Then resistors.
This end of the PCB has shorter things that the other, so I suggest this side to stuff first,
Then add your connections here. You may use the male spades, screw terminals, or bare wire, I used two types here for illustration. The Keystone screw terminals are really nice.
Relays
And finally the tall capacitors in the center.
PLEASE READ -
The current BOM asks for the -C suffix transistors, and I blindly ordered the mouser part number from it. So my transistors need to dance. Thanks bigkraig for spotting this! (Of course, i determined it after they were stuffed, so a bunch of things got un-soldered...
Hopefully the BOM can be updated with little fuss.
Shimmy shimmy shake shake
And waltz!
That's as far as I got, testing and installation to come.

Oh......
Just read the notes on the datasheet where it does indeed say the C suffix is centre collector.
My bad.
Updating BOM now.
I would be nice if their datasheet showed two pinout images showing both versions. It is quite misleading the way it is... Poorly represented and so easy to miss. I mean at least put an asterisk next to the pinout image or something.
I bought the GTA versions. I hope they will work!
