Anyone worked on Racal MA 1723 HF exciter synth board ?

If you know the set, you will know the board ....


I can only get the varactor control line voltage up to 13 V , that's
2
V short of the
spec in the handbook ..


But by reducing L17 , you can get the synth to lock at 29.9999 with
a line voltage of 13.2 V .. ae output signal is on freq and
stable ..


Is this a fault or was it not allways possible to reach 15 v on a
'older' synth board ?


Tnx - G ..
