I am looking to obtain a Philco Cathedral. I have seen a number of 70's and 90's for sale on E-Bay and elsewhere. Is the 90 that much of a better performer than the 70 that it is priced so much higher at auctions, etc? From what I have read, the 70 performs quite well and there isn't that much of a difference between the two except for two tubes.

Any insight would be helpful.

Thanks to all
