Hi Rick. I don't know anything about Randall amps. Is your speaker cab rating matched to your amp? I.e., if the output on your head is 4 ohms, is your cab a 4 ohm cab? Does the same thing happen with a different speaker cab? Are you using a quality speaker cable in good condition? Have you tried a different speaker cable? What kind of connectors does your cable have? Does your head have plenty of ventilation? Is it fan cooled? Is the fan running? Are vents clear of dust? Is the interior of the head clean and free of dust? When you say the power cuts out, do you mean that the volume drops to a lower level, or does it just quit altogether? Does your amp have tubes? How many outputs does your amp have? Does the same thing happen with all the outputs? Can you hear any scratchiness in the gain controls when you turn them? The Randall site does not have a manual for the RH300. Is the RH100 similar? If they are similar, is the problem happening with both channels? Do you have anything in the effects loop? If so, is the problem still the same when nothing is in the effects loop? Looking at the RH100, I'm guessing your amp doesn't have tubes. And apparently the output is rated at "4 or 8 ohms". |
