[Collins] removing and disassembling a 70E-8A PTO in a 310B?

[Bob Spooner]

I recently acquired a Collins 310B transmitter. This is the first piece of
Collins equipment that I have ever owned, and its been an interesting
project getting it ready to put on the air. I need to remove and open up the
PTO to replace some resistors that have changed value so that the oscillator
output will be high enough. Can anyone give me some advice about removing
and disassembling the PTO? I want to be sure to not loose the alignment
between the PTO and the frequency dial, among other things.

 

Also, the PTO Specification Data on the CCA web site says that the output of
the PTO should be 5.2 Volts across 33 pF. Can anyone tell me if that is rms
or peak voltage?

 

Thanks in advance.
