TT Converter 12 " to 10 "

CERAMIC Vintage

The JENSEN® "C" series speakers were developed because the world's supply of cobal (Co in AlNiCo) slump, making this raw material more expensive. While ceramic magnets are larger in size than comparable AlNiCo magnets of the same gauss strenght, their cost is lower. "C" series JENSEN® speakers use same cones and voice coils comparable to our AlNiCo series speakers, thus providing a similar tone but at a reduced price.

Tested and selected - Grade B - 90 +
Minimum emission of 90% on both triodes 

The PhilipsECG JAN 12AX7 (USA production, often also Sylvania manufacturing) is a high-quality dual triode preamp tube from the "Joint Army-Navy" (JAN) series and thus meets strict military specifications for durability, reliability, and stability.
It is characterized by a clear, dynamic, and balanced sound. It offers a low-noise signal, excellent amplification, and a very musical harmonic spectrum
