MJE 15034/35, higher BVCE, readily available (i.e. RS components).

Default transistor replacement

Hi apex,
Looking forward to build ax14,I want to build a stereo set.
I am having a pair of 2ski530-2sj201,2 pairs
2sc2922-2sa1216-2 pairs
mjl21193-21194-5 pairs
can you suggest if i can use these for ax14, And what would be the optimum voltage to be used.
Also if i use higher voltages than recommended what precautions should i take-will bigger heat sink be a good option

what would this amp be class -A or Class-B

Also i want suggestions as how to get 300 watts rms with this amp.
I need to for tower speaker which have 2, 8inchers in 1 tower and rated at 200 watts rms at 8 ohms per woofer, so 2 woofers mean 400 watss rms

i used to diy a long back, its been several years, so i would need your guidance.
