Hello,
I had been repairing a nice old Marshall amplifier that I received for free. The thing would sound fine for a few minutes then all the sudden it's like everything maxes out and makes the loudest noise imaginable. I found that one of the large resistors had burnt out and a paired set of voltage regulators would get incredibly hot.
On the same line there were 3 out of 6 zener diodes that are rated at .5w(halfwatt) and 5.6v but were reading around 7.1v-7.4v.
Am I able to use 1w rated diodes to replace them or do I need to use .5w?
