I love MOSFET power amps, so much simpler than a Class A/B bipolar amp with all that touchy, temperature compensated bias circuitry. I remember when Marshalls started selling MOSFET PA modules, we all built our own amps at a fraction of what a Peavy would've cost. The symmetrical pcbs are neat, never seen that before - might be difficult if they had used TL071/5534 op-amps in the design (without folding all the pins up)

Whilst most XLR cables aren't power cables the connectors were rated for around 15A & so XLR was often used for speakers back in the 80s & early 90s. To make it fun they used the 3 pin connector also used for microphones and balanced line level signals - roadies often learned the hard way to double check what they were doing...

Oh My Word that takes me back. I bought a BK Electronics module back in the day 300W into 4 ohms which I put into a nice 19" enclosure. Back then I used it on a home-built "scoop" speaker (15" 250W 104dB/1W) which I still have in my kitchen. These days I use it on my front room sub (also home built, 6.5" 75W 94dB/W). Over the years it wore out a fuse with toroidal inrush. Meh. I also have my Dad's old home-built speakers (based on the 30W RS kit and which I modified) in the loft. They're a bit too big to use daily and probably aren't that good but their sound evokes the memories alright.

XLR outputs? XLR cables are not power cables like banana Plug cables . Speakon cables or 1/4 jack cables. you would never see that kind of output on a crown or qsc JBL amp ETC.
