I'm trying to figure out how it's put together before I start soldering. As Paolo mentioned the only mystery part is the transformer T-SC-1 on the parts list - it looks like a custom order. I don't know how to characterise it without destructively pulling it apart, and unfortunately they don't sell them separately.
There's another four without the tube now listed: https://www.ebay.co.uk/itm/265151344483 The kit is listed as configured for 8SJ31J by default, and the documentation linked further up lists the wiring for 3SJ1J/5SJ38J/7SJ32J. No idea if the power requirements differ and requires resistors changing on the circuitboard(s), or if they are plug-and-pray drop-in replacements once you've changed the pinout. The auction page says it can be used with 3LO1I/7SJ33J/8SJ31D/8SJ40/8SJ42J/8SJ40D/9SJ105Y14/12SJ102J/13SJ38J/13SJ38D. Unfortunately without knowing the transformer operating characteristics I'd be hesitant to plug in anything else. I'll probably try to replace the fuses with polyfuses in the future, socketing them for now, and taking measurements while unpopulated for easier case design later.
