Does anyone know if it's possible to add a bias pot to a Simul-Class amp (Mesa MarkIII)?

I'm Looking Into This Also. The Only Problem May Be Spacing On The Pcb. The Bias Resistor Is Buried Between Caps. My Mk 111 Has A Low Bias Problem Now-approx 15 Ma. How Is The Bias On Yours? What Tubes Are You Using?

I can't say what mine is, I'm looking into this for tonal reasons.
