I have found instant glue to be good enough.
It gives a very thin, no air, connection from the flat face to the tab sink.
As an experiment I ground down a To92 to nearer the shape of an Eline transistor.
I continued grinding the flat face by taking about 1mm off before the emitter wire became visible.
On the curved back face I ground off about 2.5mm before the collector and base became visible.
If one wanted to experiment with high power through a ground down To92 with two (back and front) sinks glued on, I suspect one could go as far as 600mW continuous with some (unknown) measure of reliability.

Heres a pdf file with all the resistors, capacitors and transistors labeled on the pcb board for anyone still building these boards
Be carefull, pdf is wrong. 2N5401 in place of Q16 instead of BC550C. (npn vs pnp).
After so many years i am building it, has anybody used 56V rails safely? or should i make changes somewhere?
