Ok, it just arrived in the mail. It's actually a DC1 first stage (seems a bonus to me) but a DIN type with yoke adapter. So, a bit concerned about be knocked in the back of the head. Hopefully that won't be the case.
Not Din...well you need to send it to an official Din disposal site.. which, I just so happen to be. I will make sure that it gets to play with lots of other DIN regulators before, well you know, putting it to sleep.
