A while ago, I bought parts for an all out preamp build using Dave Slagle's autoformers. Specifically, the 28 step bare autoformers that need to be wired up. Description as follows from Dave's site...
28 Step Autoformer Volume Control (AVC)
The Demand for more positions and finer attenuation steps has brought about a second product. This device has 28 steps and provides attenuation from 0dB to -52dB in 2dB steps.This uses a similar approach as the $200 kit but has a 28 pin bobbin in place of the 14 pin. When wiring this device to a switch with fewer than 28 taps you simply assess your gain structure and choose the appropriate steps.
Price: $500 a pair
I also bought a remote control solution from Intact Audio along with a Goldpoint stereo blank as well as a selector switch. The GP kit also has the stand-offs for balanced if you ever go 4 deck. Descriptions of these are as follows from the Intact Audio and Goldpoint sites:
The Intact Audio Goldpoint Remote Control Kit Specs:
$123.00 USD
Goldpoint Stereo V24C Custom Attenuator (blank), P/N V24C-2
$75.00 USD
Goldpoint Selector Switch, 2 Pole, 3 Position, 1 Deck, P/N 2P-3T-1D
So now I'm selling because I don't plan on using a dedicated preamp anymore. $858 in parts, selling for $700 shipped in the CONUS.
Also willing to sell stuff separately.
Thanks for looking!
