No - 4.9V AGC voltage which should be over 6V at saturation hence the
question about the generator and it's output.
Thanks for the pointers - I was looking for relative loss to the input
signal anyway so will carry on tomorrow in more detail. Tonight was a quick
poke around to see if I could see anything obvious. This K2 came from ebay
and was like this when bought by it's present owner so I don't know if it's
always been like it. I suspect a soldering problem somewhere as the
insulation stripping on the toroids doesn't look very clever but don't want
to jump to any conclusions just yet.
