HI everybody,
First post here, great forum.
I have a VH4 (serial 000144) for a long time now.
Until now it worked flawlessly, but now, when I switch it on I have the 4 channel push-button lit and the mute switch is blinking
I can use it "manually" but it doesn't work wwith my kitty hawk anymore.
I suspect the midi board.
I have removed all the tubes and checked it again, and it still doesn't work.
I hope that Pieter Diezel is watching this thread to help me !
I love my amp, I have tested tons of other amps and I always come back to my VH4.
I'm not bad at electronic in general so if you can guide me I might be able to fix it.
PS: by the way is there a way or an upgrade to make the bias adjustable ?
I see no trimmer or pot on the pcb, only a switch on the chassis for 6L6 or EL34.
Thanks in advance.
