Default Re: Hope to start an audio amp with CV415/CV4046/TT15

This is a do not try this at home really, but I managed to add a variable load to the psu using a small Halogen lamp to dissipate some of the load and therefore heat. S200AF driven by a 2N3439 a Zener and a few resistors.
This give me a clue as to the output Voltage I can expect under what every load I use, looks like the full 300 Volts i require is out of my reach at 50mA+ draw but for a fun build it will do me for a single amp.

Time to crack on with another chassis.
