Wouldn't that be fun? I don't see any inputs like that, though. On the first page of this thread is a photo of the back panel, showing jacks labeled R, G, and B, but they are identified as test points in the manual. Likewise, there are test points for I and Q.
I told myself I couldn't start on this guy until I cleaned up some of the long-delayed and half-finished projects I've had sitting around for as long as 13 years. Only one more to go, and then I can get busy on this.
I have assembled a complete set of good tubes for it and I have a sackful of new caps ready to install.
