Tapco Thump TH-15A Amplifier repair ..#2

Hey all, just joined AAC and have had plenty of enjoyment reading through this thread as it may prove valuable for me in the near future.

Background - I just bought one of these active speakers through FB Marketplace (was in a Church) that's faulty.

As per the seller - intermittently loudly pops/crackles - and they have had a service tech look at the unit and it may have a crook DSP board - but is intermittent so I need to further test to fully assess.

I'm sure will be digesting this thread a few times if I can fault this speaker as it's all gold!

Cheers

- Timmy
