Have acquired this B & W 2500A from a silent key estate last summer but it is time to get it up and running.  Cleaned up beautifully and it produces full output easily however - having trouble with keying circuit.  Keys up the first time but not the second.  Put it in the standby mode and it will key up again. 
Has to be in the Q1, Q2 and 'maybe' the C 52. 

Anyone have this situation?   Any comments or thoughts on the 2500A.  Sure is a beast....
