Sent speaker out to be reconed. In the mean time I've replaced all paper and electrolytics.
Got the speaker back and installed. Powered up and all I have is a low volume hum. Checking 
voltages using pwr tfmr center tap to 8uf (62) Ive got 300vdc on 8uf (63) ive got 100vdc.
Doesn't seem correct to me. I've got about 35vdc on the plate of the 42 way low. Ohmed out choke
(59), Field coil (46), output transformer(44) and the voice coil (44) all good.
I have not restuffed bakelite blocks yet could that be the issue. 
Thanks in advance.
