Haven’t heard of anyone doing it. It’s a fairly busy pcb, would really have to go over good to pull/cut the right parts.

Converted my rockerverb 50 mkiii to cathode bias. It now sings like a rocker 30 with reverb and effects loop. Half power specs on the el34’s are identical to my rocker 30. It’s reversible and no drilling on the chassis. Would be cool if Ade included it in future versions of the rockerverb like the Custom 50.
Rockerverb is a nice amp but there is something very special with cathode biased el34’s that just does it for me!

I love the cathode biased EL34’s on the R30. I think its what makes the Rocker 30 what it is. The new models with EL84’s are cool amps, but just not the same.
