Did you test this?
Is any prototyping functional or just a schematic? 🙂

Useless location for the heat sinks, out in the middle of the board. Individual clip on heat sinks probably limit 1 hour rating to 10 watts.

Looks like a poor clone. The originals used TO3’s - on larger heat sinks mounted out in the middle of the board - where the fan blows.

I couldn't buy the parts for the clone for what the Crown original costs...

That’s true of any amplifier. The only way to save money is by getting stuff for free(ie, burnt out donor amplifiers) or pennies on the dollar surplus (computer grade caps, heat sinks, chassis materials and transformers). At regular Digikey prices, expect to spend two thousand bucks building a $400 amplifier.

Did you watch the video?

...can you share the schematics...

Did you watch the video?

The mid-board heatsinks are drivers. The main devices are off the ends so they can screw to a big plate.

The schematic is shown in the video.

My computer doesn't do videos.
