Went yard-sale-ing last weekend. Found a Herald RA-10A amplifier.

Really clean, nothing appears or smells burnt.
AM-FM, multi inputs. Takes a total of 10 tubes, none were included. I have checked and all the tubes are still readily available.

I have checked Sams's and Antique Radio, and I can find no information
on this unit.
Any help would be most appreciated. (hate to think I wasted $20) :xfingers:

thanks Stu
 
This sounds like it could have been something imported from Japan in the 1960s. Usually a small quantity was imported by a big retailer like Olsen and they would put their name on it or some English sounding name like Herald. It probably has good output transformers; you will have to draw out the schematic but I would definitely suspect it is a variation of the Williamson topology.
