I agree. A little too close for my comfort, but to each their own. My liquids are always kept at least an arms length away. No jewelry either when around electronics. Learned that from an old Navy tech about 45 yrs ago.

Starting from the front-end PCB and early prototype testing, and ending with a finished "product".
I'm using it as a main power amp in my audio system now
Great build.

Default Rod Elliot P101 build

Inspired by Burning Amp, I just finished my new power amp. This is Rod Elliot's design, with his soft-start board and a diyaudio power supply board.

Shockingly clear and analytic so far with my (ridiculously efficient) Pi Seven speakers.

The case is not what I would like aesthetically, but for now it does the job. The metalwork is part of an earthing network that terminates in a star by the IEC socket and at the output end of the power supply.

Thank you. The heatsinks are ridiculously large - they are barely above room temperature. I might wind up the bias a bit to see if it makes a difference.

Maybe next time I want to build an amp I'll saw the heatsinks in half...

Here are my three Maplin amps from the 1980's.
Left hand side is 225WRMS bipolar amp using 2n3055 and mj2955.
Top right is bipolar 50WRMS amp.
Bottom right hand side is 75WRMS mosfet amp.
I bought the first two off ebay faulty and repaired them.

Well, the heat still distributes to the front sections, however they are definitely less warm than the back ones. This is a result of not enough thinking when arranging the PSU

Very valid observation Already thinking about moving the relays right to the output terminals (and probably switching to the SS ones)
