Neve 1073/1084 switches - shorting or non-shorting?

[River]

Anyone know for sure? I assume that they're non-shorting, but it would be nice to have that verified.

Thanks,

I had assumed that they were non-shorting partly because they have the 4.7M resistors between each position, which I thought were likely to eliminate those pops.

Still, I don't know for sure.

Look in the manual, my thinking is there not shorting also because of the 4.7M resistors.

I'm looking into a group buy for switches etc but need a little help sorting it all out and these are the questions I'm looking at and for so that we get the right stuff.

The post is in the Lab.

In a 1073/1084 all switches are shorting!

In most cases you'd want to use a shorting switch for stepped attenuators, BUT... (here it comes):
When I compared a shorting vs a non-shorting switch for my 1290 project, I found that using a non-shorting only causes very soft clicks when you switch the 5 dB steps.

I also found that the shorting switch caused a significant CLICK when the second pre stage switches in (at 55dB). The non-shorting switch didn't do this. Neve put in an "OFF" position between 50 and 55 dB, and I think perhaps they might have done this to remedy this click and have the best of both worlds.

Because I'm using a PCB mount, 12 position rotary, I didn't want to waste precious switch real estate on an off position so I went with the non-shorting Grayhill 71BDF30-03-1-AJN without any remorse.

are frequency selector switches usually shorting or non shorting?
and do they pop and click if one uses non shorting?

Can i bump this question?
