Ok, crap, sorry... I cant remember where you guys mentioned that site where (prob China) where you can get super cheap stepped attenuators ala Goldpoint. Sorry I know such knowledge is sacrosanct. I'm a cheap bastard.

Here's one for $55 shipped. Scroll down the page.

sorry - I guess I need to add more info - I'm looking for the mechanism so I can put my own resistors in. Kind of like the Goldpoint but not $110 a pop. - thanks much!....

I cant believe I didnt bookmark it to begin with! - sorry again!...

Picky picky.

Be really careful, there are plenty of switches out there that "look" like they should work, but are non-shorting switches.
For what the high end pots cost, the Goldpoint switch is very fairly priced.

Ok, Granger, fair enough.

I was hoping to outfit a stepped attn. with some Tants for about $100 pops.

It's reasonable to assume 23 resistors per channel for a simple series string attenuator, or 46 resistors. The cheapest tantalum resistors I see are $3.45 (though you'll spend more to get the values you need in different wattages), so that's up to $160 for resistors.
It'd be a shame to spend that kind of dough on botique resistors to then cut them to fit your cheap Chinese eBay switch, which may or may not meet your expectations.

You know when he puts it that way ;D...John

FWIW - I used the 2-deck 24 step version of these to make some attenuators for my FPIII: http://www.partsconnexion.com/controls_rotary_connex.html (http://www.partsconnexion.com/controls_rotary_connex.html)
I bought 2 of them and just used one deck of each so that I could still get dual mono. They seem to still work the same after about a year and a half. I did use RN55's for the resistors and it was at least a small step up from what I had been using before.

Huh?
