2008 101B running 1/2 power, class A, NEW, with only 2 x EL34 installed.
Had it for 2 weeks and running just fine with every day use.
Everything tested and functions correctly.
The rear on/off switch stopped working - amp stuck in ON state.
Switch toggle feels loose. Remove the chassis and damn, switch is PCB mount.
Put it back together and use a power strip for on/off power.
Amp on and warming up - all lamps and tubes glowing.
Flip the standby switch to on and there's a quick flash from the back of the amp
and then no sound. Everything is still on though and tubes still glowing.
Shut it down. Replaced the OTs and tried again.
Zero pop when I flip the standby switch and no sound.
All tubes glowing normally and footswitch and lamps function.
I have a call and email in with Joe at Bogner.
Any ideas would be appreciated. Thanks.
 
Update.
The 5 amp main fuse is fine.
The 1 amp H.T. fuse is blown.
Anyone know what H.T. means?
