Hi guys, just like the title says. Im trying to build a bipolar cap multiplier with ECB pinout darlingtons, which are the opposite of tip142/147.
What transistors are out there? Thanks in advance

I don’t think anybody makes an ECB pin out equivalent of the TO-3P/TO-247 anymore. That would have been the TO-127 and you’ll be hard pressed to find any of those anymore. OTOH, I doubt anybody is making FAKES, so if you do find some surplus somewhere they are probably real. Last TO-127 parts I saw for sale anywhere were SCR’s, so that wouldn’t help.
In other words...unobtainium. The only thing that comes to my mind is BD681G/BD682G (onsemi) but those transistors comes in TO-126 package.
Not exactly a direct replacement but that's close as you can get. Dunno.

ECB but on 0.1” centers. No SOA to speak of, but using it to power a preamp it would work. The leads may or may not reach the holes in the pcb.
