Power Supply, tube amplifier

Flea-Power tube amplifier launches end of 2017

Launch of Flea-power tube amplifier end of 2017

In the end of 2017, a new Dutch SE tube amplifier will be launched. The name “Flea-power” is   among other things used for amplifiers with low power (0,1 to 10 Watt). The low power of this flea-power tube amplifier is no restriction to fully enjoy the music, as long as you use the right speakers.

Most important features of the Flea-power tube amplifier:

  • stabilized power supply , powering both pre-amplifier and powerstage.
  • No electrolytic capacitors, only foil capacitors (MKP) are used.
  • No negative feedback.
  • PCL82 and 85A2 in the stabilized power supply, EF86 and EL95 as pre-amp and powerstage.
  • Stepped attenuator as volume control (24 steps)
  • Point to point soldering and use of turrets.

Ever wanted to try-out a tube amplifier at home?

I have made 3 amplifiers specially for trial by people that want to give it a try for 14 days. The only cost is transport cost. The amp has to be sent back to me every time so I can check it to be sure the next person will get a perfect working device again. All this is on a base of good trust.   I will send the amplifier in a solid packing.

A lot of attention is paid to the set up of the components and the quality of the soldering.

      Hello Geoff,
      First I want to apologize for my late reply. Although I did set up the site myself, I did not know I should first approve the questions in the admin part of wordpress before I could see them. Although the name is audiokit, I normally don’t supply kits to build this amp. The price as you see it is a completely finished and working amplifier. If you wish, I can of course gather all the parts and make sketches for you to build it yourself. I will send you a personal message to discuss this matter and see if I can do a suitable offer.
      Kind regards,
