Larry, You might check with CUI (cui.com); they bought Tectrol a few years ago and might still have data on Tectrol products.
If the pinout of this converter conforms to the majority of ones that I have seen, the two pins on the left would be the input. As this was intended for VFDs, I would expect that the top two pins on the right would be the 30 VDC output and the bottom three would be the 3.7 VAC filament output, with a center tap. Often the center tap is either grounded or perhaps elevated a few volts DC for cathode bias when used with multiplexed displays. Just my guess!
