RE: REVIEW: PSVANE WE845 Tubes

Just a few historical corrections:

the 284 was WE's version of the 845. Like most early ones in that size, they were rated at 50-75W dissipation but later went to 100w, like the 845.

the 284A was a metal plate tube, as was at least some of the 284D production. the 284B (and some 284D) had graphite plates. One version of the B had a top-cap, I believe. I don't think there was a 284C. None had the pipped-top bulb, although that was present on the earliest versions of RCA's metal-plate UV-845. So, they are really going just on style for that piece of the design. From the looks of it, these psvane tubes are based on the later design WE 284D graphite plate tube, in terms of the structure and support.

I have at least 3 original NOS WE 284A and D tubes, but haven't used them so can't comment sound-wise, however they are basically the only metal-plate vintage 845 (along with the RCA UV-845).

Thanks for the review,

-Ed
