n_maher Posted April 3, 2010 Report Share Posted April 3, 2010 33 Step 100K Stereo Volume Control tube Preamplifier - eBay (item 150423738955 end time Apr-13-10 19:23:07 PDT) No personal investment, but Craig wanted to know so I thought I'd ask If the specs are right I think it'd probably suck - 1.2db/step x 33steps = max attenuation of 40dB. It might be worth buying just the switch though and populating it yourself which Craig could easily do. Quote Link to comment Share on other sites More sharing options...
Craig Sawyers Posted April 3, 2010 Report Share Posted April 3, 2010 If the specs are right I think it'd probably suck - 1.2db/step x 33steps = max attenuation of 40dB. It might be worth buying just the switch though and populating it yourself which Craig could easily do. Hmm - I'm suspicious. If you look at the AK Audio Labs website, there are some nice things listed (MM pickup cartridges, SE tube output transformers etc) but the website does not inspire confidence. The seller just lists AK stuff, so possibly the eBay organ for AK? And what does this attenuator offer over eg a DACT? Switch on the website is available separately for $155, FWIW.

n_maher Posted April 3, 2010 Report Share Posted April 3, 2010 And what does this attenuator offer over eg a DACT? Allegedly much finer adjustment (1.2dB vs. 2dB) but that won't mean much if its max attenuation is really only -40dB. Most folks have issues with the first 20dB of adjustment on typical steppers which is accomplished in the first 5 steps. Quote Link to comment Share on other sites More sharing options...
Smeggy Posted April 4, 2010 Report Share Posted April 4, 2010 interesting... they also have this one. 33 steps @ 1.5db for $320 Quote Link to comment Share on other sites More sharing options...

Craig Sawyers Posted April 4, 2010 Report Share Posted April 4, 2010 interesting... they also have this one. 33 steps @ 1.5db for $320 I'm still very suspicious. Have a look at item 150399998323, now closed and zoom in. This is a 1dB per step! The thing to note if you zoom in is the pig's breakfast of resistor types - there are Dale ones, blue ones I don't recognise, ones with colour coded values. Almost looks like these are cobbled together using whatever job lots of resistors the guy gets hold of - hence the wild differences in attenuation per step and different resistor manufacturers in the same attenuator.

Smeggy Posted April 4, 2010 Report Share Posted April 4, 2010 maybe it's a new trend, different resistor types that sound better at different volume levels and it's all a very carefully worked out scheme ..or maybe he's just a hack. Quote Link to comment Share on other sites More sharing options...
