Hughes and Kettner Warp 7 100W Head, Loud hum and no guitar sound until maxed

[batbob]

I measured the DC on the speaker out and it was under 10mV so I'm happy that it's all behaving nicely now.
It sounds awesome turned up loud again, instead of the humming and crackling I was getting.
Many many thanks for your help and support.
I've added some chip points for each of you that have helped as I appreciate your assistance a great deal.
Cheers, from a slightly deafened, Bob
