I'm looking for the following:2x 2SB647 C (Must be suffix C and not AC)2x 2SD667 C (Must be suffix C and not AC) [/list]

Most likely they were made with exactly the same process and then binned, where AC is higher grade.
Yea, I tried with the AC version and they did not work in the circuit I was intending on using them in.So I'm still looking

If you think that transistors are so precise devices that C and AC would makes so much difference that circuit won't function, you're clueless. There likely is more deviation in parameters within C suffix than their average value differences between C and AC.
That might be the case that the issue is with the circuit, I don't really care tbh since its going in to an exact replica of an 80s synth Also, BUMP, only looking for 2sc2291 and 2sc1583!
