Those voltages look almost exactly right - you only need to go to one decimal place at most. Just check the adjustment slug hasn't fallen out of the coil - that frequency is so far out it has to be either that or a tuning component. There was no need for these oscillators to be crystal controlled, just to free run at approximately line frequency. Yours is galloping!
I'll get the manual out tonight and copy you the setting up procedure.
