[time-nuts] Achieving maximum performance when driving 5370A/B inputs

[Bob Camp]

Hi

That's the one, right down to the description of the pots. If it doesn't become a working counter, it's cheap enough to be a parts donor. Of course having multiple counters all with the exact same broken parts doesn't do much good .....

For the external arm level control I might go for a fixed level and forget about the pot entirely. It's been about 20 years since I've played with a 5370, so I"m drawing a blank on the display update control.

These are the display update control and the external arming level control.   These were custom HP pots with a funky (and delicate)  switch.  They had brittle plastic shafts.    Gee,  how do I know this...  could it be that a large percentage of the 5370's for sale have the same defect?
