New OR120 build. Blown HT fuse = HALF voltage?

[antieatingactivist]

So, I finished my OR120 clone and it sounds phenomenal. I put it in the back seat of my car and somehow it flipped over. Nothing looked damaged, but when I fired it up it wen't POP and went to half volume and sounding horrible. I took it back to the bench to do some testing. The plate voltage read in the 200's. I noticed the HT fuse had blown. Possibly the bias pot could have gotten knocked forward when it tipped over in the car causing the fuse to blow, but my real question is: Why do I still have over 200 volts on my plates when the HT fuse is out? That cant be normal and I can't find a wiring error.

Schematic pointer?

Hey, I figured it out. The schematic I built off of actually has the fuse in the wrong place. here it is anyway.
