High Quality, Rugged, and Most Popular
         Audio Amplifier and Signal Normaliser for FreX


Professional, long history, high quality biological amplifier rich in features that provides opportunities to research multiple frequency therapy regimes.

Will produce AC or Positive Off-Set DC signals with all the audio frequency wave forms FreX produces. Also produces its own, extremely high quality and very fast square waves.                                    


  • Rugged construction AWS hinged enclosure. Takes the knocks and spills providing excellent protection to the amplifier circuit.

  • Power dial provides adjustable output power between 0 volts to maximum voltage (configured to 18 volts)

  • Microphone control dial allows feed-back signal to computer to be set between 0 volts to 0.5 volts.

  • Red and Black color banana terminal jacks for connecting leads to contact stainless steel tubes.

  • Audio/Square wave switch selects between FreX's audio wave forms or the PFA's internal high quality square waves.

  • AC/DC switch allows us to output frequencies in the AC polarity or the DC positive off-set polarity.

  • Bio-Impedance circuit keeps frequency waves true and correctly formed when under body load.
  • Safety lock hinged AWS enclosure provides easy access to the internal PFA-7 compartment for battery replacement.

  • RF shielding plate keeps the FreX signals clean if the PFA-7 is used in a noisy electro-magnetic environment such as wireless networks and mobile phones.

  • Comes with battery holders to accept 12 by AA (1.5 volt) batteries which produces an excellent 18 volt signal at 0.5 watts. Batteries will last a few hundred hours of heavy use.

    Allow 48 hours after submitting your order to hear from me. If you haven't heard from me in 48 hours, chances are my reply got caught up in a junk mail filter, so send me a message to let me know. e-mail Ken

    If you require multiple amplifiers, are a reseller, or you are unsure of what you need, send me an e-mail and we can chat. e-mail Ken

    Batteries are no longer included. Australia Post recommends not to send batteries by international air cargo - atmospheric pressures and scanning devices can cause them to leak and become flat. I will advise what batteries to purchase locally when you place an order.

    Refund Policy : There is no refund policy in place. FreX and my amplifiers are made available for research and experimental purposes as an introduction to RIFE Frequency Therapy and as such are very budget priced. Providing a Refund Policy would see substantial price increases.
