Hey all
Got my first vh4 and i love it. Peter told me that it needed new tubes so Got a new set Of el34 and 7 new preamp tubes.
I put in The new tubes. Set The AMP to el34 on top Of chassis. Master to 0. Cab as load. I set my multimeter correct.
Set The Black croc in The middle and The red to one side. This World perfect. I set it to 65mA. Turn The AMP Of for 5min and put The red wire to The other side. Turn on and it Reads -28mA.
I go back 2-3 times but same result. A put The AMP back together after putting bias to 65mA on The side i could get a good Reading off. The AMP Works and sounds okay. But now The 2 middle red ligets on The back lights up and The fuses are burned.
So now is The Big Q. Could my faulty bias Reading be because Of The burned fuses ?
I am not sure if i had this problem before tube change.
