I have the Supro Keeley Custom 12. It had one Chinese 12AX7 in it. I swapped it with a GE 12AX7, but honestly the Chinese one worked and sounded good. I kept it and it’s in my stash. FYI, Supro amps are the bomb.
I’ve got the same amp. I’ve had for 3 years and it didn’t have Chinese tubes. I think when David sold the company a couple of years ago they went down hill.
Chinese tubes can sound great if they are the right ones. Some suck and some can sound better than a name brand. If it sounds good, it is good. Diminishing returns on tube rolling.
Well that was weird. They should use the same tubes as you said, no idea why they did that. I've seen many videos about the Supro Black Magic so maybe it was an error? Cause they all sounded pretty good especially using an Overdrive boost 🤔
I was looking to get an "inexpensive" tube amp a couple years ago but was under the impression tubes were not only going to be hard to get but were going to become very expensive. Supro was one I was considering so yeah, If that's true then it's def a cost saving measure to "stay competitive" in that small tube amp market. I basically gave up looking for one because of this tube "crisis" that was coming. Did the pricing get all stupid on tubes or not?Would love to hear it when your done fiddling with it. Stay Safe!

I've had the BM for 7 years with zero problems. Original tubes and speaker.
