Hi
Built a Quickie and have a B1 buffer that I have kicking around,so I'm going to mount it in the amp as a separate output in parallel to the existing output.
Where would be best to connect after the o/p caps or before ?
Cheers
Rob

If you connect before the coupling caps, the plate voltage of the tubes will be present at that connection. 

A fair amount of this will be shunted to ground when you plug it into the B1, and you'll probably draw an arc or get a spark.
