Transistor help for Scott A416: F632 / 1861

Hi,

I just got a Scott A416 along with the associated tuner.
The amplifier has a shorted driver which reads 1861.
The complementary drivers is a 1860.
The schematic also shows 2SA/2SC equivalents but I can't read them.
Hopefully the Scott A426 schemartic uses the same drivers which I could read better but not correcly.
FINALLY, I found the same drivers in the 407 servie manual:
- 1860 / C1166 (2SC1166)
- 1861 / A661 (2SA661)

Can anybody confirm the two equivalent references and, if any, modern subs that I should use.
The outputs in those models are all 2SD789.


Thanks,

David
