Hi. I've recently bought some second-hand speakers that are a lot more power-hungry than my previous speakers so am in the process of refurbishing and tuning a 'Playmster Pro Series Three Power Amplifier', a kitset amp designed by Electronics Australia with kits put together by DSE and Jaycar. The guy who built it was a bit... agricultural and I can see how to make it sound better. I'm also upgrading and replacing the filter capacitors in the power supplies (it's dual mono construction with two 300VA toroidial trannies).
The issue I have is that it has no speaker protection and my speakers are irreplaceable (rarity and my budget considered). I have two speaker protection PCBs sourced from AliExpress that look up to the task, well designed with heavy duty relays and thick signal traces made thicker by having the solder mask removed and solder added. My problem is that I can't fit them and their power supply into the amplifier case.
So I'm planning on putting them in a box between the amp and speakers with speakers in and out connectors on the back. Just checking to see if anybody thinks this isn't worth doing for any reason? From what little I know they should work fine like this, it's just a little fiddly.
Thoughts?
Cheers,
