I have a identical generator, but mine is labeled LAEL 145 instead of MIAL 145, so I figure it to be more recent (MIAL later keep its original name only for capacitors, potentiometers and other parts). It is also equipped with a Ech4 and an unmarked octal black glass tube as rectifier, could be a 6H6 but I don't know for sure. E1r tube was probably used only in early series: it was a military all purpose triode exode used at its time in all stages (even as audio output and rectifier!) in some military sets, this for having only one tube type to keep as spare. In an old radio text i read that it is electrically an ECH3 but with theECH4 connections layout.
