What is a good substitute for Sanken MN130S and MP130S (MT100 Case)? These might be custom part numbers for Onkyo (not sure).
Anyone know what the closest standard Sanken part number is?

These are a factory matched, complementary pair with a 20MHz Ft. Finding substitutes will likely come down to your matching jig, technique and choice of test current rather than the particular transistor type. This specification covers both N and P types: MN130S datasheet
I'd look in the Sanken catalogue for similar TO3P transistors and match them as best you can with genuine source, currently available P/N types. Bipolar Transistors ｜Sanken Electric

I was wondering about that since almost all of the numbers in the MN130S/MP130S datasheet match that of the 2SC4468/2SA1695. However two are different: The MN130S/MP130S are rated 130W (Sanken 2SC4468 datasheet says 100W). Less concerning is that the MN130S/MP130S has a higher minimum hFE.
So are the Sanken MN130S/MP130S larger versions of the Sanken 2SC4468/2SA1695?
Maybe selected version for P hfe rank. The die must be same size inside, as the internal capacitances are same.
Dissipation is not very critical in most class AB application.

Ok. That makes sense.
As it would turn out one old chassis (Onkyo) has the MN130S/MP130S and another (Yamaha) has Sanken 2SC4468/2SA1695. So essentially the same. One even has genuine 2SC2240 too. (And also nice drivers.)

I examined an older dead TEAC and found a mix Sanken 2SC3855/2SC3856 (front channels) and 2SC4468 (surround channels). The datasheet looks very similar to 2SC4468.
Any idea why 2SC3855 or 2SC3856 would be on the front and 2SC4468 on the surrounds? The datasheet does not seem to indicated that the 2SC3855/6 is obviously better than 2SC4468.
It isn't really important I guess. But I am just curious.
Would any of these (2SC3855/2SC3856/2SC4468/MN130S) be suitable for a MA9S2 clone?
Hi, I don't know the MA9S2, but these are all good transistors. For higher rail voltages and/or low impedance speakers, the 2SC3856 is the best choice, because it has higher A and W rating.
I would not expect, that anybody will build a real MA9s2 clone, as it is quite overcomplicated amplifier, using many parts. But for the original output devices (2SC2922/2SA1216) has same chip inside as the 2SC3519/2SA1386.
If You build the chineese clone, you can use any output devices, as it has no relationship with the original MA9s2.
I am planning to build the one shown in the attached picture. (The files you gave me a while back.)
I have genuine 2SC2240, 2SC5171 and the MN130S/MP130P (and the 2SC4468). I have a smaller number (three pairs) of the 2SC3856.

This is not M9S2, but something between PM8006 and PM11. I developed it to myself.
M9S2 is a high power, bridged amplifier with 6 pairs output devices, so a real monster...

Do you think these devices are suitable for your design? MN130S/MP130S & 2SC5171/2SA1930? All are real/genuine taken from old receivers.
