GssL 20th Anniversary edition

Don't be confused. I'll explain:
- BOMs and Reichelt Part Lists should be updated by now.
- the referenced Corrections "Rev 3 needs following..." need to be applied. It's in the blend Circuit as outlined, and the wrong part is in Side chain HP switch.
Let me know if i can assist you..

I'm still a bit confused about the errata

The errate under this header is not relevant to the rev 3 board.

Errata to make the test run board perfect

Its just left there to the handful of people who are building the test board...

...and none of it will make a difference between a unit just blowing up or not. If it did, it wouldve been posted in bold and repeated 20 times.

@Gustav Are you aware of any other switches that could directly work on the switch pcbs? I was thinking of maybe using some grayhills and wire them.

There is something about the feel of the lorlins that I really don't enjoy

Sorry, I dont know of a switch that shares the exact footprint.

I also happen to think the Lorlins are great for most applications - including this one Of course, you can wire up anything you like, how you like, which is the great thing about DIY.

So this will do it for Threshold, Gain, Blend, Colour trim?

Speaking of Wiring:
As i am using NRG illuminated Push Switch (like SSL Solid State Logic) - i found need 560 Ohm for the LED switch. There is no dedicated LED Resistor (or connector) somewhere on the PCB, correct ? Guess i can wire it to Pos12V and Resistor on the PCB.

Is there a definitive wiring guide ? As i see the pads like "Bypass in" (just as an example) and the associated X101-4 ( i assume )
If not i can try to start with one and get corrected when i am wrong ?!?

I started here:
Excel (2nd Sheet for Wiring) - please do see it as a discussion point - NOTHING VERIFIED yet - Out of that i will provide wiring diagram
Excel ist editable if you want to fix things.

That would be extremely helpful ! I've been reading a lot through the various threads and guides out there and I'm trying to figure it out myself as well

Yes, that should do it.

 

[Andado]

Yes, that should do it.

Thanks Gustav

See attached for example of the connector relative to relays.

pin 1 carries 12V
pin 2 goes to relay switching
pin 3 bridges return voltage to relay switching over a drop resistor (handy for an LED)
pin 4 is connector to GND (also handy for an LED)

So in essense, you wire the switch so contact is made between 1 and 2 when you want to activate the relay
If you wire pin 3 to + and 4 to GND on a LED on your switch, if will light up when you make contact between pin 1 and 2.

You can also use this set-up for a toggle, wiring 1-2 to the toggle, 3-4 to the separate LED, or you can omit the LED and just use pin 1 and 2 to make the contact on a switch.

Varying the resistance within reasonable amounts will vary the LED intensity. 560 ohm seems awefully low. I would try with the 3K in place first, then adjust to taste.
