Silverface to Blackface

Can anyone tell me where the best info is on converting a SF Twin to BF ?

Thanks !

Which SF Twin is it?

What year was it manfactured?

There where a number of differences, mainly the output wattage.

If it is the ultralinear, you may be out of luck.

Sorry, It's a 73 100 watt with MV.

Here is a link to the schematics for a start.

At a quick glance, the MV circuit confuses things.

I'm using the AB763 to convert. Is this the correct one? I think the part that confuses me most about the MV are the Reverb connections ,and what to do with that. The other thing is the balance pot (which I have already added a bias pot on top of that ) ,and whether to leave it pretty much as is ,or change it to match the layout of the AB763 ,and do I match the component values ?
