Do a parametric search.

Try MJ15003.
Vce 140 V
Ic max 20A
Jaycar have them for around $8
TO 3 case.
Essentiallly a big 2n3055.

Large 48v linear power supply , now running quite well although I had to
buy a voltage reg :(
junkbox let me down

You used to be able to get 100V versions of 2n3055's. I used some in an
amplifier back in the seventies.

You could try 2n3442's or whatever they evolved into/replaced them.

** Motorola brand 2N3055s ( in Aluminium TO3 packs) were usually capable of
*sustaining* 120 to 140 volts with the base and emitter shorted. But this
was not much use in practice as the collector current had to be kept to no
more than a few mA at such high voltages. The Safe Operating Area (SOA)
specs allowed up to 1.5 amps at 60 volts Vce for 1 mS.

One of the best available NPN power transistors is the MJ15024 - it has a
SOA spec of 2 amps at 80 volts Vce for 0.5 second - with an upper limit of
100mA at 250 volts.

By comparison, power MOSFETS walk all over these devices.
