[GreenKeys] New Model 15 owner, getting it cleaned up and running!

[Duncan Brown]

Steve,

Welcome to the group & the would of TTYs!

I would look into the area of the selector magnet.  It sounds like maybe 
the armature is not dropping when a new character comes in. Try 
increasing the spring bias on the armature.

I can't give  you any more specifics as I am mainly a Kleinschmidt guy 
(US Army TTY repairman), although I do maintain a few M15. M19, M28 for 
the AWA Museum.

Good luck & Have fun,

Duncan Brown, K2OEQ
USASA    31J30

Antique Wireless Association
  Communication Technologies Museum
    Asst. Curator, Commercial Equipment
(also chief TTY op & repairman)
