The 39-116 project: the beginning
#13

Did some checking this evening. I found my one lonesome hi-fi P-P transformer with a 4/8 ohm output and wired it into the set so that it would work as closely as possible in place of the factory transformer. The audio sounds pretty good, overall.. but because the plate load and output impedences don't match well (the set uses a pair of 42's (6F6 equiv.), whereas the transformer is designed for four 6L6's in P-P/Parallel) and the output impedences is fairly critical to obtain the proper negative feedback and tone control range. So..... I will have to have something that more closely matches the original.
