[time-nuts] A counter for phase measures

[Bob Camp]

Hi

The relay *can* be replaced. Not so much with the input amp. If it goes, you lost the counter. The displays also die from time to time. Like the relay, they can be replaced.

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...
