the problem is i was using my vh4 at a gig recently and the pre amp tubes stopped working about 10 mins after turning the amp on and soundchecking. anyway i noticed the volume was swelling and decreasing before i got a burning smell coming from the amp head. i turned it to standby and then turned off the amp. i have just replaced all the preamp tubes and put in new power tubes aswell. the power tubes seem to be working fine but the pre amp tubes are not lighting up at all. if anyone can be of assistance i would appreciate it.
 
Are you getting sound?

Did you check the fuses on the rear of the amp?

Did you re-bias your new power tubes?

Some preamp glass doesn't light up very bright, remember that.

no im not gettin sound at all. i checked the fuses but im sure that none of the pre amptubes are working yet they are brand new.
 
I assume it´s the rectifier for the preamp tubes.
