Hi, new member and first post, so be kind

I just built two of theese boards, one working fine, the other one however is only opening one relay.

I powered them from a 15VDC powersupply i had from before, using 12V relays that might be low, but the three other relays are working fine.

Now my skills in electronics are REALLY low all i could find out was that this relay got now power to the coil, and the Ohm was different over the last rectifier then all the other ones, so i swapped it for a new one.

Now i get power to the coil, but it still wont close...

I messed up my order for parts so i have double of everything except the relays, so my question is: can it be anything else than a faulty relay?

Sorry for my bad english (im Norwegian) and for the poor explanation (i am a plumber)

Howdy, question about source voltage (and I don't think this has been specifically asked from my travels through the thread. Apologies if I missed relevant comment) and here goes:


Based on the commentary here from Post #50:

Does that mean if I'm planning to use a main PSU transformer with 18 VAC secondaries, then for K1 and K2 it would be appropriate and workable to select an Omron G5LE-1A4-DC9 as alternate components:
G5LE-1A4-DC9 Omron Electronics | Mouser Australia
and that way I could simply take a feed off one of the 18 VAC secondaries to power the board?

Thanks in advance.

This looks like a straight up typo in the BoM to me.

The "TLH" in the part number quoted by dbis appears to refer to a Vishay make component. I understand that the component is generic but it wouldn't hurt to update the BoM so that a directly locatable part is called up.

And, just for fun, the listed 400V rectifiers (i.e. D3, D4, D5, D6) are coming up as obsolete for me and Mouser is redirecting me to this alternative:
Find Electronic Components | Mouser Australia
Any foreseeable issues with that?

I am looking at using this board in an amp that does a touch over 800 watts into 4 ohms... Does anyone have any recommendations on which relay I could use? I will run a separate 12v transformer

The RLG suffix breaks down to RL="Tape&Reel" and the G="Pb Free"
It's the same diode as in the BOM otherwise.
