Anyone have any experience of faults on these? I don't seem to be able to
get the RA117 one going at all and although the RA17 is ok at at the moment
it seems to make its own mind up if it's going to work consistently or not.
I've tried swapping valves and tweaking the inductors but can't get a 100
kc/s output at all.


****Hello Don and the list,hope you are all well!

1)Recap and reresistor the thing excluding for the moment the silver mica
caps. 

2) Make up octal male to female extension cable.

3)Check that you actually have V13 fitted as CV4014/6BE6 and V15 as
CV4009/6BA6.

4) Follow the manual!!

5) If that doesn't work,fling the silver micas and replace!

Works every time!!!
