The Reverb Loud Humming problem has been solved thanks for the help it was the Preamp Valve V3 that was causing the trouble; I replaced it with one of the old Valves but I have noticed that the older Valve does not burn as brightly as the new valves is this a problem?
And a general question about Boogie Mrk IVs are they always as noisy even in clean mode recording this amp is quite a challenge I have a gate to stop all the noise going to Tape. And in overdrive all hell breaks lose I have removed the fan (pulled of the cable)
I have had this amp sent to Mesa Boogie and they say alls well with the amp, I never had this noise level with my Quad preamp or Marshal amps.
I use good quality cables a Gibson les Paul custom and a Fender Eric Clapton.
