If only the frequencies changed then you should be able to
either change the tuner or use a "tuner subber".
In the states almost all tuners were built by a few companies.
All had the same needs, B+, AGC, IF output and when used
filament & AFT. Electricaly easy to interchange usually.
Its the physical differences that will kill you.
Tuner subbers were a tech aid. Its just a solid state tuner in
a box with a 9 V battery & gain (AGC) control.Plug in the IF
cable & you got an outboard tuner. We used them to prove a
bad tuner & see how the rest of set ran before doing an expensive
tuner job.
BTW hows about some chassis pictures ?? I love to see the guts
of strange TV's
