WTB: BAD attenuators for HP 54503A scope (and alike)
« on: July 04, 2018, 11:33:35 am »
As title says, I am looking for one or more bad/burnt out input attenuators for my 54503A scope, it should have the part number:
54503-63402
1NB7-8303

I want to experiment with the possibility of removing / repairing the relays on it.
