Hi,
I just hooked up a TSE-ii 300B that is behaving well with a Hammond 290CX. I'm getting 385-390V B+ with a 5AR4 and a 33uf 1st cap, which was my goal. If you actually download the datasheet, the HV compares a bit higher to the audio series than you might expect because they are tested with 120V on the primary instead of 125V. I imagine the guitar/"lay down" orientation isn't for everybody (and should be isolated from a steel chassis), but they are so common you can save a few bucks.
I found what I think to be 290D2X or other Bandmaster replacement at a used instrument shop for $25 and am going to give that one a try on an SSE board. They don't carry the same price advantage new, though.
