Note on 13 Sept 2012 : Telfon PCB is a much superior material to fibre glass( FR4) in terms of loss and electrical isolation, and can restore the musical weak signal which is lost when signal is propagating in FR4 boards. We are proud to announce that we can now deliver the kit with Telfon PCB instead of fibre glass PCB as a kit option. The extra price for Telfon PCB is US$9.00 per kit. Buyers who want Telfon option please add US$9.00/per kit during the payment. Telfon PCB is green in color instead of red and the thickness is 1.6mm instead of 2.0mm. Note on 1 Sept 2012 : We are now delivering Fairchild MOSFET FQA19N20C/FQA12P20 rather than IR/Vishay's IRFP240/IRFP9240. The Fairchild parts are the better parts to be used with this circuit as has been well known in the diy circle. Fairchild parts are more expensive but we decided to keep the old kit price to get more customer satisfaction ! This is the full kit of a pure class A MOSFET amplifier, with reference to F5 class A amplifier. The design takes minimalist approach to attain low distortion and exceptional musical performance. The kit features 1% metal film resistor, Japan-made power resistors( the pictures showed normal metal film power resistors - we are offering better quality resistors !)Nichicon FW electrolytic capacitors( at the power rail for improving power supply impedance) and matched input JFETs ( 2SK366BL and 2SJ107BL --we only provide genuine Toshiba parts !!). The PCB is the latest incarnation, with thick board( 2mm) and thick copper ( 2 oz copper -- 75um !!) This is a single channel amplifier kit. It requires two kits to form a stereo amplifier. PCB dimension : 10.5cm x 6.2cm We provide schematic and part list by EMAIL to buyers. The component values are also marked on the board for easy intuitive assembling. We also have bare PCB for sale. Please check our other auctions. We do air shipping worldwide at US$5.50. We welcome combine shipping. For the power transformers, we recommend Noratel 18Vx2 300VA that can be purchased here : http://www.ebay.com.au/itm/18V-0-18V-300VA-240V-Transformer-Noratel-/271720398589?hash=item3f43cc3efd On Apr-07-11 at 01:42:40 PDT, seller added the following information: SquareTrade AP6.0 SquareTrade squaretrade warranty v2.0 Track Page Views With Auctiva's FREE Counter
