Default Perdio TVs

There have been a couple of threads recently about Perdio TVs including at least one oddball.
I have included below some Perdio television job numbers copied verbatim from my old (undated) typewritten list
I have omitted some items like UHF amplifiers and power supplies since the job numbers were used for internal costing purposes so included in-house test equipment.
A couple of my comments in braces.

34 - 9" Portable Television {This would be the Mk1 which was exhibited at the Radio Show but not sold as far as I know}

45 - 9" Pallion Port. T.V. {The well known Mk2}

66 - 8 1/2" 405/625 Home Market
67 - 8 1/2" 525 Line Export U.S.A {Suspect this was the design for US bases in Arctic - not sold}
68 - 19" 405/625 switched Home Market
69 - 8 1/2" Monitor 405/625 (Video input)
70 - 14" Monitor 405/625 (Video input)
71 - 8 1/2" 625 Line Export

77 - 8 1/2" Portarama for 405 to 405/625 switches Covbersion Kit
78 - 8 1/2" Monitor 625 (Video input) Imhof 'Minilok' Cabinet
79 - 8 1/2" Monitor 405 (Video input) in Portarama Case
80 - Ditto 625 Ditto
81 - 19" Monitor 405/625 switched (video input)

138 - Export 625 VHF T.V.

170 11" T.V. Transistor
171 11" TV Hybrid {The last job in my list}

I have the original job 66 (405/625) circuit diagrams and have photographed them to pdf but will not post them here since the Portarama 3 Trader sheet is available on site. I downloaded this sheet (I only have the radio DVDs) and did a rough check to confirm the same. The only difference I spotted was an extra OC81 (instead of diode) and preset RV5 for frame sync and some voltages.
