[Megatron Electrostatic Headphone Amplifier]

I purchased a megatron board and power supply board from Joachim. I believe I have a complete list of the parts necessary to build except for the following. I was wondering if anyone would be able to guide me to an appropriate source for these items. Any help would be appreciated:

Thank you gentlemen, I will look for some STN9360's.

AliExpress seems to have these with the marking 2SA1968, TO220. Are these equivalent?

I've purchased the megatron board and the power supply board from Joachim. It appears the parts that the 2SA1968 is hard to find. Can someone please suggest a source for these? Also, are there any other hard to find items for this build. Any guidance would be appreciated.
