Description
A solid linear british-made Farnell power supply for more demanding jobs. 30V 10A / 70V 5A
Status
Broken (Not SO solid, then !).
- Replaced shorted output transistor
- Replaced burnt resistor, but still ...
- Output goes to maximum with no voltage control
- amplifier is now attempting to turn output off, and there seems to be no more shorted transistors, but output still 53V. May be leaky o/p, or problem with S1.
- I broke an output terminal
ToDo
- Fix
- Replace output terminals (ideally with better ones)
- Make side panels (Laser cut acrylic would do nicely)
- Replace front and back panel screws
- Fit new mains lead
- Place in usable location (maybe under the solder oven, on a stand, with nice long thick DC leads added).
