What I've heard is also that the input assembly is different -- mainly, more robust and harder to blow out with over-voltage. But there's no real difference in the timing specifications.

Hi David,

I will check with another guy tomorrow (the last
surviving technician), but one person "in the know" has this to say:


================================================================
What I remember is the input amplifiers are very different. As a result, some of the boards and pots and switches associated with it are different.
I don't remember any significant differences beside that.
My recommendation for someone buying one through eBay is, whereas it is hard to get replacement parts for both, getting parts for A is much harder.
Try talking to (xxxxxxx) who is the last surviving technician familiar with the product.
=================================================================


  If I find out any more details, I'll post them.  There
are a lot of sharp experimenters out there who may know
the answer and will get it to you before I do.

intervalcounter



Can anyone tell me what is the difference between the above two instruments?


Does anyone have any operating manuals in electronic format?
