[Boatanchors] VT-269

[mac]

Same base diagram as the 6SG7 as Carl mentioned.  Same as the 6SK7 too  
except that the cathode and the suppressor grid (pin 3) are internally  
connected so plug compatible in most cases with 6SG7, 6SH7, 6AB7, 6SJ7  
as well.  I would recommend plugging a 6SK 7 back in the socket and  
returning circuit/component changes (if any) to original.
