In my manual all the RF coupling capacitors, C1, C4 & C11, in
the 1792
front end are shown/listed as 1uF.

The manual is Issue 8.5.85-350 and is for the RA1792
(83000,82129 and 85830)
apparently these model numbers relate to different
synthesisers.

The guy that I bought the manual from wanted to know the
serial number etc
before he supplied a copy to me.

The manual quotes the frequency range as being 150kHz - 30MHz.

Brian's 50v rated capacitor went short circuit and proceeded
to put the 15v
supply to earth via an 18 ohm resistor needless to say it
cooked very quickly!
Perhaps that's why they changed to 100v rating in later
models?
