@Cubdriver, Pat that Tektronix looks a beaut, the internals are easily fixed relative to the front panel (I think) . The front panel on that scope looks immaculate. Can't wait to see it in action.
I bought what I thought would be a 'donor only' unit for my other FT-101 but this unit I think is too good to hack to death, I have the tubes it is missing and found the knob missing on fleaBay (wasn't the same seller though!!!) This unit still has the protective plastic on the front panel - I think it will have to go.
Currently am battling my way through the HV section of my, new to me, Tek 453, definitely one dead HV diode (non-thermionic) and maybe more, so am getting a few spares in before I tackle it too much.
