Neurochrome Modulus-686

What IS a Guardian circuit? Surge protection? Soft turn-on?
And kudos to Stuart for observation!

A speaker protection circuit.

I only know because when I was ordering the boards from Tom he explained that regardless of the configuration, if you are using the 686 boards you must have a Guardian for each channel

Thanks. I have reconfigured the board. You have saved me some disappointment later in my build.




Time to order the missing one.

I found that one. It looks very tight in a 300 mm case. I was thinking going for 400mm.
It is almost a shame to hide those transformers away as well...

What did you guys use for a soft start?
My Toroidy transformers have shipped (2 x 24V, 400VA) so I need to sort out a good soft start so I can test the Power 686 boards.

I used Tom's V1 ISS board - guess that isn't an option anymore as he's replacement it with a V2. Pretty much the same features though other than selectable soft start delay and emergency shutdown for Hypex and Purify boards.

Must find out if my 86 has one! Firebottle.....?

No it doesn't but the 3886 power chip has a lot of built in protection.

What are you using as a soft start Alan?
