On the SR620 the power supply also seems to go from time to time. Both have the normal keyboard and display issues, but those can be fixed. If you go back to things like the 5335, the weak point is the input amp, it blows if you get +5 on it. Like power transformers - not a replaceable item...

Another weak point on the 5335 is the relay. We had to replace it and 
the relay-holder, but once that was done, it was back up operational.
The 5335 ticks in as the most human-friendly of the counters at work, 
while the 53132 is competing with the 5372 as being the most 
human-unfriendly, where the 5372 has more capabilities to present, so it 
gets used more.

Cheers,
Magnus
