Heath Model 10-14 Oscilloscope Empty Heath Model 10-14 Oscilloscope

I recently picked up a Heath model 10-14 scope for cheap. it does not work. there is a short somewhere that I am trying to track down.
scematic when I power it up it blows the internal breaker, if I crank it up slowly it roasts R301 in series with the top diode bridge. my guess is that the problem is somewhere on the vertical deflection board because the 6dj8 and 12gn7a were both roasted. the schematic is blurry and I don't know if this link will work. any help is appreciated, I just don't know where to start. this is my first time with a scope.

I wish I could help but I do not have a schematic for this scope. I have a 10-12 scope and schematic that I assembled when I was a kid. Maybe they are very similar? I'll look at my schematic today.

I took this to a different forum and I bought an original manual. I have also fixed the overload problem. there were some extremely leaky caps.
