The quick shutdown low capacitance PSU is included as a “bonus” board. It’s unpopulated. You need two diodes, a 22uF cap and an LED and 15k resistor for the indicator.
There was an earlier version of a shutdown that used two transistors. That is not used anymore for this simple circuit.

This is the correct schematic. Sounds like there is some confusion on how to connect these to your amp. Let me make an easy to understand drawing.
Although the Pre-order pricing is now over since we are in production. I have several sales in my shop that might give you a similar savings on this and all other items in my shop.

hi xrk
i had on my mooly amp a turn off pop because i did the installation direct after the cap bank +V.
so if the voltags sag because off very loud listening one SSr switched off....or both channels...
now i re installed the SSR with the AC/DC converter (meanwell post before) direct at the main power socket.-->turn off pop is gone.

I have two Version 2 boards that I plan to use with a new amplifier project, but I need a longer speaker connection delay than the standard 3secs. Can I check that if I change R108 from 100K to 200K I'll get a 6sec delay.
Thanks
Thanks
Hi nautyboy
Yes here IS the timer setting at SSR.
Written in the thread post #747
Once it trips, it takes 2 seconds to come back on after the DC is removed. I think the timer is based on a 100k and 22uF cap. R108 and C108.

Good news. First article is finished. Functional tests next, then full production run will commence, followed by individual testing at the factory.
Good news. I just got word that the production completed and is shipping out to me today. I should have them in under a week.
The GB boards have arrived! I will start sending them out this weekend.
Closeup:
Tested with 24v supply and ohm meter - it works of course. Each unit is factory tested to work already.

X,
Wondering if you ordered the 6 spare bonus boards for me. Let me know how to pay.
Thanks,

Good news folks. I packed all orders for fulfillment and they go out tomorrow (except for those of you who requested I hold off due to timing issues).
Actually, packages are going out today as I forgot yesterday was a federal holiday honoring Martin Luther King, Jr.
