Default Transistor substitutes for TA-5650? (v-fets excluded)

Looking for some help to put together a list of readily available substitute transistors on the main amp board for the ta5650. Some of these i may need, some for other members should they need the info in the future. A complete list for the whole TA-5650 does exist but most of the substitutes are obsolete themselves. I could try to substitute them all myself but i am new to the game and know other members will no doubt pick out a better substitute then myself.

Transistors as follows

2sc1663
2sa835
2sa705- Alternative bc556b, gain may be a little on the high side?. A few members have used them for input differentials including myself and they seem to work fine.
2sa677
2sa678
2sa639
2sc926a
2sc1363
