• Country of origin: China
  
• The Groove Tubes GT-12AU7 preamp tube is based on a design from the Ei factory in the former Yugoslavia
  
• The GT-12AU7 is an excellent quality large-plate European-made driver tube, styled after the famous Telefunken line of dual triodes
  
• The usual application for a 12AU7 tube is as the phase inverter that drives the power tubes
  
• These are very well matched, and so are highly recommended for Ampeg SVT's and other amps using this tube as a phase inverter
