@reimarc a 300B filament is 5v/1.2a while a 45 is 2.5v/1.5a. A 2A3 is the same filament voltage as a 45 (2.5v) but requires more current (2.5a). So, a 2A3 may work on the “45” setting but only if the filament supply can provide the additional current. Best to check with the manufacturer.
2a3 Tubes - Favorites?
Hi all,
Doing a quick search, it's been some time before specific 2a3 tubes have been discussed, and I just recently got a 2a3 SET amp, so I'm curious what tubes everyone prefers.
Ideally, looking for recommendations of tubes that are easily obtainable in 2024 - they can be new production like the Takatsukis, or easily sourced NOS. In the past when I've asked around in various places about tubes recommendations, I often hear about tubes that are near impossible to source nowadays, so I'd like to avoid those recommendations since they're pretty much irrelevant if they're unobtainium now.
Thanks for any suggestions!
