I ordered a Harbach keying mod for my newly acquired SB-200 after 
hearing people tell me about the high keying voltage on the relay.  Dumb 
me, i didn't check to see if that was actually the case or not and 
panicked because i wanted to use it with my K3.  I also needed a set of 
new 572B tubes so ordered both.  While changing out the tubes i see that 
the soft key mod is already installed in the bottom of the amp  so the 
one i have is not needed.  If you need a soft key mod, Harbach type, i 
have one NIB never opened for sale for $30 or $35 postage paid.
