Hi
   This may have been explained before but I cant find details anywhere

I want to disable the PAB as I have no use for it .on my HRM50W, (that I built)

then use the relay  for PAB to switch the mid boost . and possibly the bright cap

This is to allow me to get a clean sound without mids boosted then OD sound with mids boosted.

or is it possible to put an extra relay operated by od channel to switch mid boost when selecting OD . ?

if anyone can help much obliged but I need as much info on how to do this as I struggle to follow the circuit  ie which cables would I short on pab relay to disable pab . then how do I make the pab relay switch the mid boost ?
 I have some idea but some one with better knowledge confirms then I feel happier doing mod .

thanks Derek
