RE: Questions about 6BG6G amp build (schematic) Grommes 216BA

I'd put more filtering on the bias supply. And an adjustable pot. Maybe, change R27 to 22K-ohm and add a 10k linear pot? But, the values may change when you tap the bias supply off a new transformer. Looks like you'd need around -45VDC.

I'd sub a 100mfd/100VDC cap (C3) on the bias supply.
