1965 to 1967
Page in progress (April 2025)
Some brief notes on circuit diagrams for the Vox Super Continental organ (late 1965 to mid 1967):
The main sheet supplied by JMI to dealers, who will in many cases have been the first port of call for a buyer looking to have his Super Continental repaired, was TMO/015 (illustrated below), a sort of companion sheet to TO/065 for the single manual. The prefix "TMO" stood for "Two Manual Organ". So far as one can tell the sequence mostly encompassed component layout sheets, i.e. sheets illustrating the position and value of resistors, capacitors, and so on, on the PCBs.
At present, two TMOs for the Super Continental are known: TMO/015 and TMO/002 (referenced by name alone, see the pic in yesterday's entry). TMO/001 and TMO/003 to TMO/014 may have been "Works Only" sheets, supplied to dealers only on request.
It is possible that there was some gap after TMO/015. TMO/030 is the main sheet for the Vox Super Continental II (released in the autumn of 1967) - circuit drawn out by Albert Hogben at some point in the second half of 1967, but the information panel later adjusted first by "Vox Sound Equipment Limited", then "Vox Sound Limited". TMO/071 breaks the "two manual" mould however, being for the single manual Vox Corinthian organ.
Component layout sheets for the Guitar Organ had a sequence of their own: "GTO", presumably "Guitar Transistor Organ".
TMO/015, the main sheet for the Vox Super Continental provided by JMI in the service manual produced for dealers in early 1966:
TMO/015.
TMO/015, Vibrato unit, block 7100 - referenced in JMI's "Theory of Operation" booklet - see this page.
The information panel, drawn by R. Lester, no date.
