[Premium-Rx] [OT] Search for HP5328A Option 030 schematic

[Carcia, Frank A. HS]

Hi,
	Wiggle all the plug in cards in case the fuse is good.
	my unit had an intermittent filter cap in the 5 volt 	supply. A
good counter, hope you got the good time base.
	Gee I could use a copy of the book also.	fc

Hi Alberto ...

The first thing to check is the little in-line fuse that is behind the 
channel C bnc connector. The connector actually unscrews from the front and 
the fuse is inside. I've had several of these counters with either a 
missing fuse, or a burned out one.
