I have a Vox AC15H1TV 50th Anniversary hand wired amp that has a microphonic EF86 tube. The tube that's in the amp doesn't have EF86 on it anywhere but that's what the manual calls for. I don't even know who the manufacturer was. Anyway, I need to replace it.
I am not a technical tube amp guy and know very little other than how to get a good sound from the amps and realize when something is not right with them. I need some help. I couldn't get a clear shot of the number on the tube without taking a few photos from an angle and getting a few digits at a time. Here's what I have now.

I need some recommendations for what to replace it with. I have a tech in Phoenix that has a lot of NOS tubes. He may even have an RCA, Phillips, or Sylvania replacement. There are so many different manufacturers, JJ, Sovtek, EH, Groove Tubes, etc, I don't know what to do.
I use this amp strictly for recording. I have taken it to a couple jam sessions and it was plenty loud enough for those. If I need something louder I have a Twin Reverb and a couple pedals. I'm not concerned about having the most volume I just want something that sounds great. A lot of headroom is not a priority for me either. I can turn it down to clean up the sound. I use it crunchy most of the time. It has a 16 ohm 25 watt Greenback in it FYI if that has any bearing on a recommendation.
I have read a bit about the EF86 tubes and a lot of what I read tells of their susceptibility to vibration causing them to go microphonic. I have been considering building a separate amp head cabinet for it anyway so I can put the speaker in another room when recording. That should help with the vibration issues.
