Is this system also known as the ZT-D? When i worked at an Iwatsu shop I think there was just one ZT-D left near me, and it's in the town next to where I live. Maybe one more in NYC that may have been replaced by now. I'm thinking the phones were 2 pair?

Or maybe the Omega IV is a different one - I'm picturing a brown and tan cabinet cover. I know it was somewhat common for those to blow a 3/10a fuse on the station cards. Hopefully the customer has realized it doesn't make much sense to try to repair that system. As mentioned above, it would be very unlikely for any tech today to be familiar with it,
