Stk4050v to M2 implant

Junfer · 25th February 2004, 01:39 AM

Hi Guys, here's my experimental Stk4050v implanted to a Kenwood M2 Power amp. This Kenwood was trash by the last owner and sold it to me cheap, the power supply section is in good shape so i use it for this project and guess what? it works, although the wiring and my home made Pcb needs improvements and also needed to add the Mute and Protection Circuit, if i find a simple circuitry. Any suggestions for improvement will be very much appreciated> See attached Photo.

These are links to the datasheets of both STK4050V .And STK4040V in whch you will find the protection circuit schematic

Hi Metal,
Thanks for the link, Now i have the circuit diagram for the Mute and Protection circuit for the stk4050v, but my problem is to find the type of transistor that was use in the ciruit that was not indicated. has anybody done this circuit so i could share with type of the transistors that was used. Thanks: Junfer

You can use 2SA1207 for the sensor transistors,and for the latch you can use 2SA1209 as PNP,and 2SC2911 as NPN.

Hi Metal,
Thanks for the information, i'll try to find these transistors and build this circuit.

Keep me in touch,and try to short the output to see if it works,so I can build it
