Description
SV1 requires a low- to medium-impedance raw bias supply to properly support its performance. However, the stock bias supply in most guitar tube amps is woefully inadequate, so we offer a solution with a small discount on SV1+RBX. You can purchase these as DIY kits or pre-assembled. See the individual product pages for more details about each kit.
To make biasing the amplifier easier, add BMK2 Bias Mod Kit for 2-tubes. BMK2 will control a push-pull amp of any number of tubes.
