Description

A solid linear british-made Farnell power supply for more demanding jobs.

Two ranges - 30V 10A and 70V 5A.

Note that changing the range switch not only doubles / halves the output voltage, it also changes the meter scale. So it's fairly easy to mis-read it as 25V when it's actually putting out 50V etc. Be careful, or you may fry your circuit sooner than you intended.

Status

Working. probably.

Replaced shorted output transistor and about 6 others
Roughly working. Output controllable. Not thoroughly tested.
I broke an output terminal

ToDo

Soak test
Replace output terminals (replacements need trags redrilling - WIP)
Place in usable location (maybe under the solder oven, on a stand, with nice long thick DC leads added).

Documents

Notes

Side panels were sourced cut-to-size from ebay seller sgs132 for about £13 total. These are stainless, aluminium woud have been a couple of pounds cheaper.
