What sort of high voltage rectifier was used, do you know? When I joined Motorola in 1966 they were working on the solid state chassis (I wasn't directly involved), and they used a single solid state rectifier assembly that consisted of a stack of several hundred "high" voltage rated diodes (perhaps 1kv each). The asembly had curved side fins to equalize the capacitive current among the diodes from the top to the bottom of the stack. The units were made by Varo in Texas.
I don't know how long Motorola used tube rectifiers, but my impression is that it was just a stopgap while the solid state rectifiers were being perfected.
