FT-857, FT-857D, FT-897D Power switching repair kit. ++++ FT-857 Lots 18 and upwards ONLY !!! ++++++++ FT-857D All Lots ++++++++ FT-897D Lot 25 and upwards ONLY !!! ++++ The ONLY way of determining the lot number is to look at Q1028 and R1595
Q1028 is in a TO-252 package not a smaller SOT-89 package as on other lot numbers.A common fault on this rig is failure of the +5V regulator which destroys the input power MOSFET, digital transistor, dual diode switch, series schottky diode and limiting resistor.All resistors provided are the same physical size as required but are uprated to 0.5W.The kit comprises a total of 8 parts:

1 off each of the following items: 2SJ355 P-Channel MOSFET (Q1031) BA05FP +5V Voltage Regulator (Q1028) RT1N241M Digital Transistor (Q1035) DAN222TL Dual Diode (D1033) RB051L-40 Schottky Diode (D1020) 6R8 6.8 Ohm 0.5W 0805 Thick film resistor (R1595 FT-857D, Lot 1) 15R 15 Ohm 0.5W 0805 Thick film resistor (R1595 FT-857D, Lot 2 - Lot 17) 15R 15 Ohm 0.5W 1206 Thick film resistor (R1595 FT-857D, Lot 18+, FT-897D Lot 25+) All kits dispatched within the UK , postage is FREE.

All kits dispatched worldwide. Check the postage cost to your area.
