Hi!

Yes, the Telpro panel is a single valve audio stage with the h.t. (300V) and l.t. (25V) rectifiers plus the negative voltage for the preset brightness control – from the pics Chris posted, he doesn't need an I.F. panel!

My design to make the OP an exact plug–in replacement for the one shown missing in his photos isn't far off completion now, and I have all the parts needed to build it, including the audio o/p transformer and the correct Pressac PCB–mounted male connector plugs!
