As above gents, I’ve found of these amplifier that is hopefully buggered.
Class A/B so I should have a basic familiarity with the general design, any unobtainable parts or pitfalls to be aware of?

Looking at that general design (very similar to Alpine), the relays and emitter resistors develop bad solder connections. The relays also fail due to dirty/burned contacts.
Thanks Perry, good to note for future.
I was surprised to see relays in it, I had never seen a touch like that in a car amplifier.
I’m going to put this in the car for a spell I think, powering front 4” morel components and stock BMW underseat woofers.
It’s got me scratching my head actually, I’d like to use two channels to power the components and the other two to power the woofers. However the LP and HP filters are either in and out at 80hz and I want to send the underseat woofers a band above 80Hz and below x Hz but am having trouble deciding what x should be.
Any ideas?
