Is an autoformer (AVC) always superior to pots and resistors ?
This is an argument some of my friends made to me. AVC is always the best volume control, better than anything else such as rk50 or resistor based volume controls. Have you found this to be the case?
I am also curious why AVC is not implemented more often in high end audio preamps / integrated amps.
I’m in the process of building a simple avc attenuator with the budget autoformers from Slagle. To be used with my Sayes SET and Omega single drivers. 2 inputs with a switch and 2 outputs vintage 16 step rotary knob Really looking forward to finally being done with it. Still need to put in the rca connector and wire it up. |
@jmolsberg That's great, how do you like it? What is your amp? Do you feel the autoformers have a sound or not? Can't wait to wrap this thing up..just need to set aside some time to inhale some soldering fumes. @mitch2 , Yes all the Slagle autoformers would require a stepped switch as you're actually connecting to different taps on the autofomer, As I mentioned, I purchased the most basic units which are only 16 steps...so not a lot of resolution between volume steps but I think I'll be OK with that as I usually set it and leave it alone. At one point, he did offer some sort of collaboration with Bent where there was a remote control unit but I don't think that's available anymore. |
