[Racal] MA79 Transmitter driver

[Bcomer1]

Hi Don 

Just a quick check I have 6.28 volts p to p output at 7.3 Mhz. I do not
remember the exact situation now but I vaguely remember getting close to
a watt out when I was doing  test with a signal generator into I believe
TP3. So the output stage can deliver. I have had the most problems with
getting the drive to the output stage from all previous stages that have
to be just right.

Hello,
I've been renovating a couple of these units for a while now.
I can't get more than 3V p-p out of either of them, I reckon I should
get about 6Vp-p to give the
100mW into a 75 ohm load. I wonder if anyone else is currently using or
repairing one of these to
get some comparative readings other than those in the manual.
Been over the filters a few times and checked valve readings and changed
a few components and
replaced some missing bits but seem to have come to a dead end.
Any tips would be gratefully received.
