SV2 + VCK Power Scaling Combo
Cathode-biased amplifiers demand full power even at idle, which pulls the supply voltage down to a value that stays approximately the same, even when the amp is driven to full output. In a Power Scaled cathode-biased amp, as the Power Scale control is dialed down, the supply voltage will rise as it becomes “unloaded”. This will change the tonal contribution of the preamp at low power settings. Adding VCK to stabilize the preamp voltage to the stock “loaded” value will keep the tonal contribution of the preamp constant with any Power Scale setting.
Now you can get our SV2 Power Scaling Kit for Cathode-Biased Amps, and VCK together, at a discount!
