Quick Mesa connection question...

Almost any silicon diode will work
its very unpicky ( your IN4001, 1N4007, 1N4148, FR107, FR207 are all fine)

You dont need diodes for most low power relays since the output driver circuits have built in flyback suppression
But above 50-60 mA, I would suggest using a flyback diode.

output suppression (across the contacts) depends on the load
(AC typically uses RC snubbers DC typically uses flyback diodes across the relays load)

cool... I will put them on just to be safe... i'm not certain what the milliamp draw is on the relays. the rest of the connected items i think are quite low and should be under that threshold. I did a practice relay by popping the cover off and soldering the diode across the coil posts with the striped side on the negative coil post side as i read to do and it went pretty easy. was harder popping the cover off the first time than soldering the diode on..lol then two snips and pop the cover back on and check no internal contact anywhere it was supposed to be. triggered the relay to make sure it functioned properly and it did so i'm guessing i did everything properly. phone died while in the shop but will post a picture of it tomorrow once i'm back out there!

Thanks again guys!

Chris!

Hi, I need to drive a relay with an output of my Mesa 7i96, and I have laying around a bunch of MIC UF4007. I see that they are specific for rectifying ac courrent. Can they also be used as flyback diodes in this case?
Thank you

Yes.

Great, thank you again.
Tomorrow I should finally connect everything and test the new pc/board.

With flyback diodes its best to test manually first (say with a switch
instead of a 7I96 output)

Because you can damage a 7I96 output if the diode is backwards
