Yeah definitely tried all that. I will say that the power cable that plugs into the sub plate amp doesn't feel all that snug. It wobbles quite a bit when it's "all the way in". Same for any cable I try though.

To test the drivers, touch a 9 volt battery to the leads of each driver and see if the cone moves in or out (movement either way is good).
I had a capacitor blow on one of my first PSA sub amps just a few months in, and Tom sent me out a new amp the next day. Failures like this are rare, but they do still happen. Tom has mentioned it’s often some very minor component, like a ten cent capacitor failure, that ruins even a well built amp. I hope this gets resolved quickly!
I did peer inside but didn't want to touch anything just yet - upon removing the plate, there's very tight cabling that connects that circuitry to even more circuitry mounted to another internal side of the sub - assuming that's the amplifier or power supply unit, while the plate is the DSP and connections?
There's no light at all when I flick the toggle to the permanent ON position, so it would suggest an amp/plate issue.
I'll wait for Tom/Jim to come back to me through my distributor who I have contacted today. Peter from Deep Hz audio jumped straight onto it and contacted Tom (Christmas Day for USA). I am super grateful for them even taking a look at my enquiry at this time of year. Such great guys at PSA and Deep Hz Audio.
As you can imagine - just desperate to enjoy this system now that I am FINALLY on 2 weeks holidays. 2 days in, and bam, no sub!!
