Haha! Yeah, sorry, it's getting pretty complicated to remember all the old amps and their many upgrades (and the many unofficial ones!) when writing copy! (Not that Doc B lets me write copy, I'm too scatterbrained).
Any version of the shunt reg'd board will work with the Paramour II; the "shunt reg" variation is the only currently available version. It comes with the replacement 5670 tube. Bottlehead doesn't offer all the endless variations due to the difficulty (i.e. labor) involved in either keeping the parts straight, noting manual differences, and fixing mistakes! So that is the easiest approach.
The 12AT7 has so much gain that it can't run well with 2.5v bias, which is the minimum available with the "soft-start" board. This is especially important with direct coupled amps, such as the 2A3 version of the Paramount. For a Paramour, you can retain the LED bias and still get perfectly good performance, since it is not direct coupled. Unfortunately this is one of the many possibilities that are too many and too complicated to include in the manual. We can help on the Board here (though no promises of how fast!) if you really want to keep the 12AT7.
