TERRA medium-power house amplifiers, series HA129 Cabrio

0
Manufacturer:
Type of amplifier:
 
 

Advantages:
built in smooth gain control and amplitude-frequency characteristic

  • molded case in plastic cover
  • interstage direct channel amplification switching allows to reduce effective gain without deterioration of noise figure amplifier
  •
