McMurdo Silver Masterpiece II
I received a gift from a very good customer of mine, who was cleaning out his garage. A McMurdo Silver Masterpiece II...
Information on these seems hard to find. I am assuming it is a first variant, due to the "long" power supply chassis?
Where would I locate a schematic? I didn't see anything in Riders, nor any other U.S. schematics that I have.
I was able to get some history on the set; it originally came from Kamloops, British Columbia.

yep Brad. - a complete MP2. My price list shows cost 159.63. Either the 12 inch Jensen, same casting as the Scott AW12 pedestal - for for another $14 the larger Jensen 13 inch "Giant" version. Diagram were originally pasted inside the bottom plate of the receiver including alignment info. Not in Riders. Seven cabinet choices at extra cost (same as with Scott, but not same cabinets as Scott). Yours is the walnut finish 44"x 27" RALEIGH.
Two versions of this 12 tube radio: earlier used a pair of 2A3 outputs. Later 1934, changed to the hard to find 2B6 outputs, a quirky direct coupled power triod somewhat like the 6 volt 6N6-G. I have the early version diagram and some other info.
Early version with long amp like yours. Later is smaller amp and I have that diagram in an issue of Silver Times

Thank you very much for the information David! I wasn't sure at first if the cabinet was an aftermarket one, or something that someone had built. The speaker is the 13" "Giant". What confused me is that even though the speaker has the pedistal, it is screwed to the cabinet and there is no "shelf" for it to sit on. The power supply chassis sits sideways, straddling the front and rear cross pieces.

Excellent Norman! Thanks very much! Now I will have some reference. Looks like you spent a great deal of time researching for the drawings!
The set appears to have had some repairs; one of the transformers on the P.S. chassis has been replaced.
I am assuming that I may find minor changes or revisions once I get into the chassis restoration? From your experience, how often did McMurdo Silver make revisions or changes in their sets?

Brad, probably like Scott, where the cabinet was shipped separately and the customer installed the receiver, amp and speaker. I will guess the newer transformer in an interstage audio transformer. Don't know about evolutionary small changes in Silver models, other than the change in output tubes mentioned earlier.
However my experience with Scott radios is that when there is a departure from the diagram, and it looks like original factory work, leave it be.
