That is very interesting on the disco amp. I wonder that Marty did not go that route? Maybe send him a PM and ask?
If you really get frustrated by the rewiring process, I do seem to have 4 spare tested working DSP amps here that
I have collected from breakers over the years.......I also have the aforementioned disco amp on the shelf.
Of course, these may be considered to be "Geographically undesirable" but I don't need that many spares.

You're such a hoarder :) That's a really nice little stash, though!

Yea, (tee hee)
Actually,, I was surprised to find 4 of them. I thought I only had 2?
Go figure!
Glad the issue was sorted with a bit of .....ahem..... contact cleaner.......
Gotta love the easy ones!

Well, it's a bit intermittent as it turns out. I did some driving in Europe last week and for some legs the amp ran perfectly. For some it clicked (switched on or off) and at some points it would make a sort of ratchet noise through the speakers if you tried to change the volume. But the volume didn't change... Very odd behaviour in all. Switchinig off/on would usually calm it for a couple of minutes.Then for the final couple of trips it behaved really well. Unless the battery was a bit marginal to start with, I think it's still not quite fixed.
I'm talking to the Vendor above on WhatsApp. Seems like a nice chap, we'll have to see if this is a solution that should work but it's a bad unit, or whether he's got confused on the P38 vs Disco.

Bolt - don't throw any amps away just yet! ;)
