Ciao a tutti,

As most of you know, the TOHM (CAMAC) Kinetic Systems 1500/1502
power supplies need to be modified in order to be used (they draw
too much current from the +12V line).
Here is what this modification consists of:
- 1500: On the voltage regulator card, change R38 from 0.15 Ohm to
0.075 (2 0.15 Ohm in parallel)
- 1502: On the voltage regulator card, change R23 from 249 Ohm to
1.2 KOhm. Also, R44 from 100 Ohm to 470 Ohm.

A presto,

Ioannis & Massimo
