Today I switched on my JCM2000 DSL100 but no sound!
Looking inside (removed back cover) I found that all preamp tubes were dead (not glowing) plus V1 of the power tubes.
So tubes 1-5 are dead, 6 7 and 8 are glowing.
Anyone ideas?
The power tubes were recently replaced, the pre amp tubes were replaced one year ago. The amp is being used 8 hours per week.
