Never  had a problem with any TCS keying circuit (I've been using them   
since 1964), and cherish the keying characteristics/tone of each  type  
of surplus transmitter. This is the tone that was heard when  the  
equipment was originally used.



---------------------------
 
I don't think suppressing the back emf off the relays will in any way 
affect the 'tone' of the CW signal. Might lengthen the life of diodes 
and such in the 12v line though.
 
After all, I don't think the designers of sets really thought some 
nutter would still be using them in 60 years hence.  Their life 
expectancy must have been counted in weeks.

Now now, I think you know that I know how to look after old sets.
