Hi all, My old 80 MHz HP frequency counter shot craps, (Lites, but erratic display). Does anyone have a link or scan of the schematic and possibly a parts list for the HP-5381A? Some of the IC's are factory numbered parts, I have not looked at the NTE/SK/ECG crosses yet, no schematic :-( If you want to email me off list, use [EMAIL PROTECTED] Any help would be appreciated. TNX JIM
