Gary has them for £33 + tax but I can see you feel driven to try :whistling:

It may look good on paper, but the 542 microcode is probably based on what actually works, rather than what should work. The best you can hope to make is the 542 prototype which probably ended up in the bin.

Confidence is that feeling you get just before you understand the problem :heehee:

I started out with home brew, then went to 542's, then fitted drivers that plugged straight in to the mains and rectified it. You can never have enough volts
