Jvm Bias? and V1 tube position?

[dawnofdreamx97]

Does anyone know what marshall's specs are for the bias? and which preamp tube is V1 ? i know its usually the one closest to the power tubes ... so im guessing the one that is all alone right next to the power tubes? I wanna check the bias and change the v1 preamp tube.... any help is greatly appreciated!

The power tubes should be between 30-35ma for EL34's
And the V1 should be the furthest from the power tubes...Phase Inverter is closest to power....
