Not push pull, but a good quality set. I think it was Murphy's first model with VHF.

Yes, a good AM/FM radio, but Murphy's first was the very similarly styled A242.
As Paul says, there will be quite a few paper dielectric capacitors to replace, especially the "infamous" one that couples the audio signal to the control grid of the audio output valve (Mazda 6P1 in the case of the A252).
Its circuit reference is C76 in the official Murphy circuit diagram (10nF = 0.01uF). If it's leaky, it can damage the 6P1 and/or the audio output transformer. So, it should be replaced before the set is run for an extended period of time.
