[TenTec] 1553 Keyer

[John Graves]

I have a TenTec 1553 keyer and cannot find the circuit 
diagram/instruction sheet.  The (speed?) pot has broken off and it 
continually keys and generates tone, a byproduct of the broken pot I 
suspect.  Anybody tucked the sheet/diagram away and be willing to make a 
copy?  I would like to repair the keyer and pass it along to another ham.
