Someone who has one of these (as shown in the 1972 Centuri catalog), can you list the dimensions of the metal box? I just want to make one about that size. Thanks.

I have cloned the EP-612, I believe I found the OEM source for the aluminum box..LMB Heeger Commerce Ca. Part# LMB 139. Check out their web page. John

This might be a nice accompaniment to a LIA-100.

I'd love to see plans.

John,

Just curious if you think this is actually the same box Centuri used 45 yrs ago? That would be remarkable.

Steve

That would be remarkable, but then LMB has been around forever... BTW LMB stands for 'Little Metal Box'. Looks like Heegar bought the LMB company at some time.

I don't know for sure, the box is identical in construction as the Centuri unit and LMB Heeger has been in business since 1946. Just a guess...

John,

That's amazing. Thanks for sharing.

Steve

I believe the stock number may have changed. I only see an unpainted version. Will keep looking.

Brilliant, John !

What are the sources and part numbers for the other components ?

Thanks,

Dave F.
