![]() If you're unsure about whether the readings seem off, Google for the diode type and expected readings.Īfter soldering, make sure you cut lead ends and clear away anything on the underside of the turret board. Your DMM should have a clearly-marked diode check function which you can use to verify them. Best Practice Amp for Effects Roland CUBE-10GX COSM Combo Amp SPECS. We opted for a 12AX7 in the pre and an EL84 in the power section, which are both quite small and seemingly fragile valves, but with a gentle push they seated correctly.ĭiodes are particularly heat-sensitive, so it's worth checking them both before they go into circuit and after.
