Published on 10/20/13 at 15:50Large capacitor microphone membrane tube, based on the pentode EF86 (6BR7) mounted triode.
RC12 capsule (AKG C12 type) in my case.
This mic is not dedicated to one vote taken in particular, it is a versatile studio microphone although quite typical.
The overall construction is not very complicated, but still requires time: mount tubes, high voltage power supply and external heating, special cable and multipoint connectors ... and for my part, built on columns and washers plexyglas, as one of my old Schoeps.
(Thread construction: )
OVERALL OPINION
Made in a month with a lot of recycled parts, including the tube. Completed in late April 2013.
This is my third tube microphone, the first being a clone C12 and the second a personal schedule. Each has its own personality, even if their type C12 capsules are their common point.
- What I like in Gyraf G7 is made silky with its strident or not aggressive acute beautiful, impressive dynamics. His medium is beautiful even on delicate instruments (accordion, bagpipes).
- What I like least: nothing at the moment ...
Unbeatable price / performance, even with components of the highest quality ... but excluding labor (and fun to use a microphone that has made itself!)
