Hello, is a SBM-20 tube installable in the GMC-320+ right off the batt with no extra setup, resistors etc. ie. just putting it in and it works(and ofc recalibration)? Thank you.
Hi Searinox_Navras, the SBM-20 tube is a little longer than the M4011 and the clips to hold it to the PCB is too close to each other to fit it. You have to do some DIY stuff to fit it inside. The case is large enough, but you need to move 1 of the clips inside.
