Sound Pure's Take
Built side-by-side with "the big boys" (251E, C12, and U47), the Alchemy Series is the next generation of affordable microphones from TELEFUNKEN Elekroakustik. This series directly replaces (and outperforms!) the older and discontinued RFT line. The biggest changes are subtle, but they really add up when talking about overall performance and reliability. Throw in the fact these mics are now shipping with a flight case (previously an add on), and you have a truly exceptional package.
While you can't see it (but you'll hear it!), one of the aspects we are most excited about is that the mics (capsules and electronics), as well as the power supply (internals), are all "stuffed" in-house, in Connecticut. This undoubltely adds a big level of quality control to the microphone set.
From TELEFUNKEN Elektroakustik
The TF39 Copperhead Deluxe is an expansion of the “Copperhead” sound with the addition of a dual membrane K67-style capsule, allowing for 3-pattern selection between cardioid, omnidirectional, and figure-8. This added feature set gives the TF39 greater flexibility and options in the studio. Sonically and component-wise, the two microphones are otherwise the same.
Circuit Design
The TF39 features a new old stock American-made 5654W vacuum tube, all-brass K67-style capsule, and a premium Swedish-made Lundahl output transformer. These components create a balanced frequency response and natural tonality, making the TF39 a trusty go-to choice.
