I would think that you could make the 32-8196 work. It is wired as a standard primary-secondary step-up transformer where as the 32-8135 is wired as an auto-transformer step-up transformer. There might be some impedance matching differences but it may not be noticeable. I was referring to OldRadioParts.com. They also list one as stock number 4573-040 in the input transformers list. It seems to me that the transformer was larger than the dimensions they show. I have a 1942 Philco with the beam-of-light at home that also has a transformer that I believe was about the same size as the one in the 41-608. I can measure the dimensions and let you know.

For the part numbers I get them from the service information. This is shown on the Rider's available on Nostalgia Air but I also have the 1941 and 1942 Philco service manuals that are much more clear than the scans on Nostalgia Air.
