Default Looking for 12BH7A recommendations

I have a McIntosh MHA 200 headphone amp and am looking to roll in some different 12BH7A output tubes. Any recommendations?

Was always pleased with the NOS ones that the Tube Store provided. At the time Jon provided RCA and................. believe it was Sylvania, but I won't swear to that. In several years of use I never had one go bad. Always quiet and channels well matched. When I got my amp and found it was a newer one and did not use the 6922 I was disappointed. That did not last long. 12BH7A is a great tube.

Thanks Glenn,
The 12BH7A is a bit of a sleeper with lots of NOS options available at reasonable cost. With only 2 to swap out this will be a fun ride. I’m going to check out all of the US made tubes for sure.
