15-06-2008 | | No doubt it is all stk's. The reading on the test mode can help but you'd need to have the service manual and more than likely, knowing yamaha's protection circuitry is definately detecting the presence .
Assuming that you tried monitoring the voltages |
15-06-2008 | 50N06 bad | How can I check that the 50N06 is bad?
If those Mosfets don't go bad, what else may cause them to get destroyed?
My application is an amplifier where those 50N06 are in, and one shows short to ground on 3 legs (not right I would say).

15-06-2008 | | I soldered the bad stk out of the curcuit and measured and compared the resistance of the output stages and one was short-curcuited.
I have another problem. Yamaha uses the stk402-120Y (14pins) and I suppose, that that one i ordered is only a STK402-12 |

15-06-2008 | | Ah im such a dumbass. :lol: Of course is the type I ordered having 15 pins, but the 3rd is just missing. I just counted the existing ones. Have checked the datasheet again...
Now I´m looking forward to the delivery. |

16-06-2008 | | The anode connector usually has two hooks gripping in the cavity of the CRT. You will have to push it aside so that one of the hooks gets released, swing it out of the cavity and then unhook the other hook.
You should NOT disassemble the connection bo |
16-06-2008 | Reading resistance on Ohm meter | I am doing some trouble shooting on a boat motor ignition system.
When I measure the power coil with my ohm meter on the 2K scale, I get a reading of .929.
Is this actual value 929 ohms or 929 ohms x 2 = 1858 ohms?
Why would meter manufacturers use a |

16-06-2008 | | In this case, the resistance is 929 ohm.
Most digital multimeters have a so-called 3 1/2 digit display, which can display numbers up to 1999. Hence, all measurement ranges will be 20, 200, 2000 etc, possibly with an exception for the highest voltage and |
