[Racal] RA-1772 Pre-selector

[oldtimer]

Hello again, on further investigation I now find only the frequency
range 8-15 Mhz is not being selected in straight through mode, all the
other ranges work normally straight through and via the tuner.

It now seems like a range switch problem, or more likely one of the
switching diodes on the switch panel.

Can someone with a diagram please have a look, and tell me what the
diode number and location is for the 8-15 Mhz range.

A scan of the board would be great, (Board # DA44759  PS365).


Thanks..
