I purchased some of those RCA 6BX7GTs, and they're quite good as well. I prefer the 6BL7, it has a touch more of something I seem to favor, but it's hard to figure out what.RCA definitely makes some great rectifiers - I have 4 of them: 5U4G, 5U4GB, 5U4GB tall bottle, and 5AW4. I scored most of those for less than $10 and they sound terrific. The GB has depth layering like a $300 tube and it’s like $8. The tall bottle is a great balance for bright and airy tubes, especially with the HD600. Lots of solid EBay budget scores, if you’re patient.
I can recommend the TungSol 5U4GB. Seems to add a little more low end impact than the Westinghouse version I have, and the RCA 5U4G I have doesn't seem as sweet sounding. I haven't spent enough time with the IHA-1 to really pick out the differences between the rectifiers I have, mainly because I'm still rolling input tubes to best suit my tastes, but those are my initial impressions. I have a Brimbar 5R4 coming. Love those old English tubes!
