Re: My $25 "In Poor Shape" 3468A has arrived
The current set of probes is 34137A. The ones George mentioned have have been superseded by several models. They are priced at a modest $75 CAD. Less than what the meter cost me. Dave VE7HR

Any of you guys ever tried one of those test lead sets that have interchangeable tips? I think they are/where US made and from the 70s or 80s. I remember my brand new 3476A DMM back in the 70s came
