...Jim, really?...maybe you would like to offer up a link to the thread I "hijacked"?...would it be the one in which you accused somebody (me, again?) of "hacking" your post (quickly shot down by the moderators)?...that was my own thread, btw...
...I'm not even recommending any one particular mic, as you say...I just offered up 6 affordable and reputable tube microphone options, clearly, none of which you have had any experience with...6 tube microphones that are vastly superior to your recommendation...6 microphones that incorporate true LDC capsules, and offer 9 polar-patterns (not just the one 'cardioid' offered by the Solid Tube)...you state you own 4 tube microphones...did you know that two of your mics don't even have true LDC capsules?...the Solid Tube and the Behringer T-1 ("T" for toy) have electret capsules...read the comments for the T-1:

...three of the microphones I recommended, the AA CM-12, Stellar CM-5 and Avantone CV-12 owe their design heritage directly to AKG's most revered tube mic, the original C12...they all utilize true LDC capsules (2 of them use a 34mm 6-micron mylar edge-terminated C12-type LDC capsule found in much more expensive microphones), not electret capsules:

...or maybe you missed the analysis of the AKG Solid Tube by two of Recording.org's most knowlegable mic builders (gus & gyraf):

...or maybe you missed the discussion at Gearslutz pertaining to the performance of the Solid Tube:

...probably AKG's most notoriously disliked tube microphone...did you remove the notorious "internal foam pop filter"? (probably implemented more to disguise the fact that AKG chose not to employ a real large diameter capsule than to offer any performance enhancement)...
...I'd venture to say that the only tube mic of the four you mentioned that's 'recommendable' is the EM T5000 (which I also own and use)...that is a much better executed tube mic design incorporating a simple 12AT7 based plate-follower circuit, WIMA caps, a dual-bobbin transformer and a 34mm 3-micron mylar K67-type "true" LDC capsule...unfortunately, that mic is no longer available under that branding (similar models from the same manufacturer are available under the iSK branding)...
...so I'd recommend you refrain from making misaligned accusations, and do a little research on the products you recommend...your choice of the 14 year-old 'discontinued' Solid Tube as a good recommendation in the current $500 product range says a lot about your lack of knowledge/experience with the much improved, better-valued products coming out of China in the past few years...
