Hi John,
A good number of components have been replaced. All the tar (goudron) capacitors have been changed with ones with generous voltage ratings.
No resistors have been replaced, at least so far.
According to the Decca service data the blocking oscillator frequency should 1000c/s and the ringing frequency 25Kc/s.

DFWB.
