Default Help with Equivalents

Hi all,
My sone has two Maplin 150 watt Mosfet amps that we would like to copy, problem is my local supplyer does not stock the following transistors:
2SD872A, 2SD756, 2SD716,

I am not a boffin, but they seem to be high voltage TO92, any one want to suggest alternatives. Unfortunately I only have the stuffing guide and no schematic, but it appears to be similar to a Mosfet design by Penfold.

Any help will be appreciated

Hi

According to On semi the 2SD872 is equivalent to the MJE3055T. One just needs to be careful of the Vce.

I cant find a direct replacement for the other two devices. At least not in any references I normally use.
Your suggestion that they may be high voltage TO92 seems to be correct. According to their data sheet they are rated: Vce = 120V.
