I take it that it does not matter.... there is just a dizzying number with different current draws etc...
Honestly in this case, where it's being used as a indicator lamp and nothing else, the cheap ones are best.
The LEDs are any 3mm or 5mm LED you may have on your stash of parts. Choice of color is up to you.
Antek AN-6224 & Speaker Protection Board Relay Clarification
OK, I got totally lost in this exchange about transformers and this speaker protection board. I will be using an Antek AN-6224, 600VA 24V in a F5T V2 build. So will this board work with the 600/24V transformer providing I use the 24V relays? Or, will I have to have a separate transformer to drive this board?
Thank you in advance for clearing this up...

OK, if you don't want to get a dedicated small transformer, you can tap one of the 0-24 and use that to power the speaker protection board. I'd use two 12V relays there since they are in series, not 24V.

Thanks JojoD818 for the quick reply and for putting me back on track! Your help is greatly appreciated. I will go ahead and solder in two 12V relays on the board.
Again, many thanks for the quick and thorough reply...🙂

Hey guys,
Just to make it explicit for simpletons like me 🙂. If I understand correctly, the decision for 5V relays for 12v PSU vs 12v relays for 24V PSU is because the coils are in series.
I'm looking at this for a standard honeybadger using the +/-63v or so PSU. As such, it seems there is no standard replacement relay of appropriate coil voltage so I'll be looking at the separate transformer just for relays (looking at posts 32/36).
Sound about right?

Right. And to sum it up, for...
12V PSU use 6V relay coils
24V PSU use 12V relay coils
48V PSU use 24V relay coils
anything higher PSU, use a separate transformer or get a transformer with a separate winding or a totally separate transformer.
Cheers

Thanks for the quick reply!
Actually, now that I think about it, I'll also be using the soft-start board which has a zener regulated 24VDC.
I should be able to just tap off that right? Any gotchas/drawbacks there?

Oh no, please don't. Or the soft start relay will never engage at all.
The speaker protection board must be used with it's own power supply, either from a tap from your main transformer or a dedicated one. Anything that can output at least 250mA should be more than enough.

Since this is for a stereo amp, how do you deal with the speaker output wires crossing the power lines?
Hi,
I have two of these boards, and want to populate them for mono use.
Can R12 and the corresponding relay K2.2 be deleted and the coil K2.1 jumpered?
If there is only one relay in play, then the supply voltage must be halved.
Will the circuit still work with a 5V supply?
Thanks!

I haven't tried BC549 in there but a quick peek and I don't see why it wouldn't work. 2N2222 is also ok in lieu of the 945. 2SC828 is also a pin for pin replacement.
Just please watch out for the pin configuration when you substitute transistors.

Does the circuit need to be hooked up for the red led to go out? Right now, I am testing it without being connected to anything.

Nope, the blinking LED will go steady lit once the relays are closed and all it needs connected to the board is a suitable power source.
