back to 12v high current

Pyramid PS-36K:


I've had this power supply for quite some time so it's been modified repeatedly. It still lives on my test
bench though it doesn't get a lot of use nowadays.

- added 12v light to volt meter, powered off the 12v regulator ic
- fan changed from 24vac to 12vac, powered off unused rectifier tap
- added fan cutoff locking relay with a momentary switch on the front, so it could run quietly when needed
- replaced analog amp meter with a digital amp meter (LCD)
- inserted a resistor in the voltage regulation circuit to increase adjustable voltage range of ps
