The Integrated Amplifier which adopted the current feedback magnification circuit as the power amplifier part.

The current feedback type magnification circuit which returns an output signal in the form of current is adopted as a magnification circuit.

A principle lowers the impedance of the input terminal by the side of a return, detects current, and carries out I-V conversion of the current with a transformer impedance amplifier, and it has the structure of making an output signal, and since the impedance of a return input portion is very low, it is difficult to generate phase rotation.

Thereby, in order that there may almost be no necessity for phase compensation, it excelled in dynamic characteristics, such as a standup, and the natural energy response is realized.

Moreover, high power has been obtained by it being parallel for an output element and adopting the power transistor for audios excellent in many characteristics, such as a frequency response, a current gain linearity, and switching, as it.

The large-sized power transformer of the large power capacity of about 500 VA(s) and the mass filter condenser of 22,000 micro Fx2 are carried in the power-source part.

      Item Condition: AS NEW condition Shipping Options: Shipping is included in price. Suburb or Town: BUDERIM State: QLD Payment Method: EFT or PayPal as a Friend Reason for selling: Wife has too many Ponchos !! Further information: Selling a BLAEST RAINWEAR "Bergen Poncho" Medium Size and White in Colour. Original cost was $450. Made in Norway this is the ultimately stylish way to stay dry. My wife is a Size 14 but has at least 2 other Blaest Ponchos so this has never been used. Will be posted as an Auspost Parcel with Tracking included in the price. My Price is NEGOTIABLE.

      Apologies for the dust on the glass faceplate. I did not notice it until uploading the pictures.
       
      I would happily put this against any integrated valve amplifier on the 2nd hand market for a similar price. 60 big watts of power and quality parts throughout. Still has the original Winged C 6550's and all the valves test great. Has just been serviced by Falls Audio who also, at my request, installed a remote motorised stereo alps pot. I could not handle the dual mono pots, having no remote is worse enough but having two volume controls....No thanks......So now you can enjoy remote volume which is a necessity for myself and lazy folks alike. First to hear this will buy it. I am certain of it.
       
      In very tidy condition over all and the glass presents perfectly as does the green LED around the logo on power up.
       
      Specifications Power output: 60 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.5% Input sensitivity: 250mV (line) Signal to noise ratio: 90dB (line) Dimensions: 457 x 210 x 353mm Weight: 26kg

      Pictures says it all. These look mint and are all original. I cracked the wax seals to get the bullets polished. The aluminum had pitted and outside of painting them black and in true Kenrick fashion polishing was the only option. Note: The 075 do not come with a mounting frame for internal cabinet mounting like the 2402. They come with the supplied free standing mounts as pictured, you would need recycle a pair of cabinet mounts or buy them on Ebay, they are cheap.
       
      These have the original and first edition of the 075/2402 diaphragm, silver outer and inner rings. I have had numerous bullets and slots and haven't had a pair with the original silver diaphragms, blues and golds are most common and later revisions.
