[QUOTE="MegaGoo, post: 90696, member: 2293"] So im having a problem in which my randall shorted out the module in the middle slot of my 3-slot rm100 (see http://mtsforum.grailtone.com/viewtopic.php?t=13345) and after tracing down the resistors that blew on the module, it led back to the midiboard. so i disconnected the midi board to see if that would solve things. the biggest question i'd like answered is: is there any harm in running 1 module in the middle slot, with the midiboard disconnected. i only want to test to see if the module works, i.e. doesnt blow the resistors like it did last time so i disconnected the midiboard and this happens: with a module only in socket 1, i can play fine through the module with a module in socket 1 and another in socket 2, when i turn the amp on and leave on standby, the light on the module indicating that it is selected comes on BOTH. i was afraid to switch off standby i just cant remember if the modules shorted out upon turning the amp on, or turning it off of standby. so what is the normal response when you use the amp with the midiboard unplugged? is there any way i can switch modules? the manual channel select button did not work when i had 2 modules plugged in. maybe if i had 3? also is there any way to tell if my midiboard is indeed the problem? the traces have some wear - the copper (or whatever material) is exposed in spots. the board says rm100-F [img]http://i72.photobucket.com/albums/i178/megagoo/photo2.jpg[/img] [img]http://i72.photobucket.com/albums/i178/megagoo/photo1.jpg[/img] and if i have to get a new board, how much will randall charge about?
