Hi all,

I am looking for any information on the WECO J86464 power plant which was the main supply for the 756A PBX. It supplied the power and tones for the PBX. I would like to find a photo and any written information on this unit.

Google has not been my friend on this inquiry.

Thank you all in advance!

Best,

Joe
