in my learning  of electronics if all other toms are workingfine i doubt it is the transformer,if capasiters blow they will become convex instead of being flat.diodes can be tested using a metre,special setting see manual on metre ics look up number on top of ic and see inputs and out puts for voltage.the other toms should pretty much be the same as the high tom so compare voltages from medium tom to high..if any thing the first place i would look at is the pots,volume and sensitivity as they get dusty ect ,create unwanted sounds when adjusting
