PURPOSE
Lower noise with greater detail, transparency and reliability. Sound is further improved as NO (or less) EQ is needed with a fresh tube.
BACKGROUND
AllegroSound pioneered the "Reference Tube" industry in 1978 with the introduction of the legendary AllegroSound 12AX7B™ Original Reference Tube, the finest 12AX7 - 12AX7A - ECC83 - E83CC - ECC803 - 5751 - 6057 - 6681 - 7025 - 7058 - 7729 tube ever made, with the finest guaranty ever made, "better sound or your $ back".
In 1987, AKG (Austria & CT USA) selected the AllegroSound 6072M™ for TheTube (the first and best re-issue of C12) production and for replacement in vintage C12, C24, ELAM 250 & ELAM 251 microphones and has earned it's place as the standard of the recording industry.
* BUYER BEWARE! Sub-standard material and imitations abound, even from the manufacturer of your prestigious microphone! Tubes without AllegroSound logo are NOT the same quality.
Trust your precious recordings to one who's been offering a superior product for over a quarter Century and who cares about your recordings as much as you.
TESTING
AllegroSound 6072's are selected from New-Old-Stock Made-in-USA material c.1950~1978 in Tektronix 570 curve-tracer, Hickok 118B CardMatic, Heathkit TT-1, AKG C12R (aka TheTube).
NOTE: Not a single GE 6072 manufactured in the 1980's, or RCA "6072" of any vintage, has ever met the grade of AllegroSound 6072LN™.

CONSIDERATIONS
You need a BACKUP tube for each tube mic.
Tubes wear out, it's the nature of the beast, and session time costs more than tubes. If a tube goes south in the middle of a recording session, you're dust without a backup tube. And if you wait for the tube to get noisy before replacing it, you have not been recording at top performance!
As tubes age, they loose more and more detail and require more and more EQ (you can't get back what you've lost, and more EQ makes it worse).
The tube should be retired long before it gets noisy, or worse, fails, when it can damage other components in the mic.
If you swap in the backup tube every month or two for a vocal or piano test, your ears will tell you when NOT to put the old tube back in. If you don't have the time to do this, replace the tube within 12 months if in daily use.
AllegroTipTM - Running the mic with capsule end UP
will lower noise & extend the life of the tube & capsule.
Your recordings will sound better and your music enjoyed more with AllegroSound 6072M™ Original Microphone Tubes™

Customer feedback
" Hey there Rick: The AllegroSound 6072M+ tube sounds awsome. Very quiet and smooth, but with a clear open sound. I am very pleased with the results I had when recording a male vocalist which sometimes can be a little murky in the bottom end when recording with a tube mic. The result was a clear, warm sound. And thanks once again for all the great knowledge you shared with me that will help me to keep better tube health around the studio. Why the big, elite, microphone companys don't use great tubes like this is beyond me. They could have such a better product with the noticeable difference your tubes make!
