Vintage Synth Repair

Hello,

I am trying to design a homemade clone of an ARP Odyssey,
but I already had some difficulties in finding components.
Anyone has suggestions about where to find these please ?
- tempco resistors, wire wound 3% 1.87 KOhm, 3400ppm
- slider potentiometer 1Megaohm, 60mm
- 1MF3958 dual J-FET transistor
- 2N5459 FET, ORN: what does "ORN" mean here ? Orange ?
- 2N5459 FET, YEL: what does "YEL" mean here ? Yellow ?
- a good two-buses 3octave keyboard
and then it is not quite clear to me how to make the "pair"
in the "matched pairs" of transistors for the exponential
converters driving the VCOs: which parameters should match,
and how can I measure them ?
Any help will be welcome
thank you

Paolo
