Default Stepped Attenuator - Ebay Seiden DACT Goldpoint Elma Shallco?

Does anyone have experience with this stepped attenuator on ebay:

33 Step 100K Volume Control DACT ELMA TKD 2A3 300B tube - eBay (item 150539240706 end time Jan-01-11 20:17:34 PST)

It looks a lot like the Seiden.

Also, any experience with DACT or Goldpoint?

No experience with that particular attenuator. However, 1.2 dB/step is sizable but may be OK. -40 dB is not enough attenuation for me. My preamp (with PGA2320 as volume control) frequently makes it below -40 dB.

Yeah, I am afraid that 1.2 dB might not be fine enough.

Excellent results with the Goldpoint. Smooth and quiet operation. I also used the K&K version, but was getting pops during switching.

I just bought one of those attenuators of eBay last night... so we will see how it compares. Goldpoint and Dact are excellent.

I've been curious about those too.
Once posted on bottlehead forum and the following was recommended by someone, although i haven't tried it:

Don't forget Broskie's stepped attenuator at tubecad.com. He has a spendy version and an affordable version. The nice thing is that it functions as a balance control as well.
