I've acquired a gorgeous St. Regis cathedral radio with a tube layout of; 6D6, 6D6, 76, 38, 12Z3...Its a small cathedral. Does anyone know where I can get a schematic for it - I don't have a model number.....Thanks, Phil

I think that's the International CM in Rider 5-4. Wish I had one.

I understand that the 78 is a better tube than the poorly-designed 6D6, so you might want to use 78s when you restore it.

I agree with Alan.Seems that many of the International chassis were used in many different brands hard to find sets these days. The Kadettes used International chassis' also, and sometimes it takes flipping thru several pages of JF Riders to find a similar/exact tube lineup. In most cases, if a exact schemat cant be found, you can work off one with same tube lineup and get very good results in electronic restorations. The best thing about all these old tube radios, is that they are very forgiving in electronic repairs.
