This one came in with no sound fault!
So let's get on with it....remove chassis and connect to test speaker and power up...next check front panel to ensure all indications are working/lighting up. A quick signal in and turn the gains up...mmmm no sound...to cut a long repair story short, it turned out to be dry joints on all valve bases due to the crappy lead free solder..a reflow with 60/40 solder and she burst back to life working fully. that darn lead free solder has a lot to answer for!
Never power up a valve amplifier with out a speaker load or damage may happen!!
