Midland 77-155 info needed

[Robb]

Yup, picked up a Midland 77-155 from the Salvation Army here in town for $1. It receives, all the controls works, but has a carrier and no modulation. I'll give it to a local op once I get it fixed. Gives me some play time on the radio bench.

Is there schematic or service manual to another similar radio?
Any info is much appreciated!

Thanks, Mr. Gumby. Got the radio up and working OK. Radio was also off by nearly 700hz in tx, so I set that straight too. Gets 100% modulation now. Never owned a Midland before; seems to built with decent design and parts tho. Prolly needs new caps; but i'll let it go unless it pops back up. Much appreciated.
