[Test-Equipment] Sencore Freq Counter

[bonddaleena at aol.com]

Hi. I know this is a long shot, but hope springs eternal.........

I just acquired a mint (looking) Sencore FC 71 Counter. It goes to 1 GHZ. For some bizarre reason I collect counters. I 'think' it gores back to the days when a 30 MHZ Heathkit was 'state of the art'.... I have a lot of Sencore stuff and been very happy with them.....

Anyway, it powers up and the display is fine. However, it won't count. I just purchased a Manual for it.

There 'appears' to be damage to the input circuit directly behind the BNC connectors. I tried removing the small, 50 ohm fuse and the counter responds with "input fuse open"......

There sure doesn't look like there's anything between the BNCs and the fuse.

Gee, another (!!!) project......

thanks,
