"Yes, I see 45’s in AB have zero signal In of about 30MA  which is quite low. i don’t have figures for 2A5/42/6f6 so would have to get technical after 55 years!  B"

"They may have run the finals in class A-B, which provides better sound and less distortion than straight B. I haven't looked at the schematic or studied the spec sheets of the original tubes, but I suspect that is how they would have run the…"

"Thanks for that breakthrough Kent. I have to say thatI have become hooked on Scott’s AW’s! (Did I say that on old colleague in Wellington has given me a complete AW15 with a burned-out power transformer. I go to Wgtn on Thurs to see…"

"Great! I will take some time to really study the bottom view, but I can say for certain this set began life as a battery set. The lack of a divider resistor is one indicator, but also, as you face the set there are no capacitors mounted on the…"

"OK, looks like only two got thru.  Two more photos then: Is it now more identifiable?"

"I don't know that my photos got through so I'll try again. There was another one showing the coil spider which has no web like later ones I have seen photos of."

"Bill - I'm inclined to agree, this probably started life as a battery set, circa 1932, maybe 1933. Once electricity arrived, someone probably rebuilt the set as a powered set. It would have been possible for them to change sockets, so I doubt…"

"Thanks for your messages Kent and David. I am now rather inclined to it having been a battery set especially as there was only limited AC power available in Motueka (main Tasman town) in 1923 and the owner, Mr McNabb was a garage owner so charging…"

"Bill - I very much doubt the 2A5 output tubes were used by Scott. I would expect your guess of the 27 or 56 to be closer, and the "final" amp would still be on the P/S chassis, probably a pair of 45s for that era. As Dave noted, I have an…"

"Bill - FYI -Scott sets evolved during a model run - including the single dial 12 tube Scott Deluxe (Deluxe refers to single dial tuning) from Spring 1932 to mid 1934. For awhile, I had a really early single dial Scott (spring 1932?) and it was very…"

"Bill - I have two examples of different chassis with the 10 tube lineup - but these are all pretty custom sets. Can you attach some images of your chassis, and I need to know which tubes are in which sockets. I've made a study of these chassis.…"

AW 13 ?

Can anyone help me with info on what is a single dial spider coils 10 tube version if the more common 9 tube AW 12 deluxe. It has no tuning meter and 5 pin sockets in tree RF/IF stages and came with  24A’s and one 35 which I assume are the original fit out, but the detector and AF driver stages have been modified with later tubes eg p/p 2A5’s where I believe there should have been p/p 27’s or 56’s, Early 1932 would be my guess. I have no power unit, but assume it is the 80 + p/p 45’s one if two…See More
