Default Sales On Sound Vintage 40s Tube Amp Info

I have a Sales On Sound tube amp and was wondering if anyone has any info on it. I bought it on eBay about 6 years ago. It was made in New York, maybe in the 40s? Model # 9915 Type # A53M. I converted it to a 6L6GC (I modified a Heathkit A-9C circuit). I dont remember what tubes it originally had. Google doesnt bring up anything on it, so I assume its very rare. I would like to buy another one, so I have a matching pair. Its currently driving a VOT bass cabinet and JBL horn, loaded with Peavey drivers. Sounds great!

I did some more research on google and found out it must have been made for a dual projector system. Hence the PEC and EXC knobs (Photoelectric cell & exciter lamp). I wish I could find out more about it. And especially find another one for sale. You can email me at

I would start with eBay, and you might have to pay some pretty significant coin for one of these.
