Hey Guys
I want to do the bias mod to my Nomad head - making the bias adjustable with a pot

What resistor is removed?
There are posts here showing it but most have Photobucket pics attached, not which resistor remove
And with Photobucket holding all 3rd party pics hostage they are not able to be viewed

Any help??

Thanks guys ! !

Looking at the schematic of the bias supply, I would pull the 22K resistor that is in parallel with the 150uf cap. Replace that 22K resistor with a 50K trim pot.

Hope that helps,
