Powertube blown, hum resistors gone but fixed.

When I was playing like a normal day, I heard firecrackers sound came out from my VH4 then I know my powertube was blown.
After replaced a new set of powertubes and 0.25A slowblow tube fault fuse at the back,
I had fired up my VH4 and noticed that the overall "hum" level increased.
Another thing I also noticed that the "hissing" even happened on Ch.1 with low gain setting.
My VH4 was not quiet like before anymore.

Took out the chassis and flipped it over, I saw something wrong from my two hum resistors.
Verified with Papa Peter and he confirmed that my hum resistors need to be replaced.


I had followed the Diezel service manual sent by Papa and completed my hum resistors replacement.
Everything back to normal and thanks to Peter.

Awesome! Your in good hands with Pops!
He has helped me out a few times in the past. Still owe him that 5th of Jack Daniels.
