Default Re: Combined power-pentode and double-diodes?

I think the EBL21, EBL31 and EBL71 are more like successors/recreations of the EBL1. Or maybe the EBL31 was the octal version of the EBL1, with EBL21 and EBL71 being successors.

I don't know the purpose of the EBL71 either, it seems to be an identical copy of the EBL21 but assigned a new number by Lorenz. Maybe they didn't want customers to know they were using a, by then, seemingly outdated tube.
