Adjustable Bias Mod for M/B rect-o-verb ?

[CrsadrJoe]

I recently read (in a different forum) about the adjustable bias modification for dual rectifiers in one of Myles' very informative threads. I'm wondering if anyone knows whether this mod can be applied to the M/B Single Rectifier rect-o-verb head, and if so, which resister would be targeted?

 

Thanks in advance for the help. And "thank you so much" to those who take the time to help so many of us learn about about these often confusing topics.
