BTW,if the combo is not a good one in stock configuration, it is probable that a little soldering of a few resistors and maybe a v small cap will make the match work fine. SUTs, like all other transformers, do not have an intrinsic impedance; they reflect the input or output impedance of what they are hooked up to. So, you can probably make it work with a little technical expertise and some parts. You might want to read more on this subject on the Jensen Transformer website. They make available some very informative pdf's on transformer function, free of charge.
