I've been working on an audio project and I need to source some MBB (form d) relays. The thing is that these are quite hard to find nowadays.
After some online research I see that some people say that it's possible to use two BBM relays (with a cap in-between?) in order to create a MBB one but unfortunately I can't get my head around it.
Could someone explain in more detail whether this is possible and if so, how it's done?

2 ordinary BBM relays in series. Coil of the second is energised by the spare contacts of the first. First relay is Make, that is the in and out are shorted and second relay is Break, that is the short is opened.
Thank you very much indeed Johno. I'll give it a go although I'm straggling to visualise it...
So there are not any caps or diodes involved (other than the flyback ones of course)?
