PMG / Erricson 3 line 8 ext PMBX

It’s no great secret I collect old phone stuff, I got this Melbourne made PMBX (Private Manual Branch Exchange) a while back, and I finally got around to doing something with it.

I’ve cleaned all the relays, got all the electronics happy (still need to replace the ring generator), taken everything out, sanded it, varnished it, 3D printed replacement knobs, cleaned the glass and got it looking all schmick.

Before

During

After

Glass replaced, contacts cleaned, wooden case taken apart, treated for boras, sanded and stained.

Next up fit all the 3D printed knobs, and repaint all the switch assemblies
