With out knowing the specifics of what the name & model product you're asking about - the only thing I can tell you with reasonable certainty is that "Q13" and "Q14" are both transistors. A "Q" designation on a PCB is usually for a transistor.

You'll have to either consult the schematic or obtain the actual transistor manufacturer's part number from the transistor case itself. You will very likely be able to use a competing manufacturer's transistor for replacement if the original is not readily available.

I hope this helped!

Components Q12 & Q13 (2N 3906) PNP transistors fried. Would there be anything else blown?


It is sad your having a problem with Q12 and Q13, check the regulator

that supply voltage on the transistor 's your referring to.


Q13= 2SA1478 for Mackie SWA1501 Active Subwoofer

the supply is about +15V and -15V

My amp popped one night i disconnected the power an took it out an pulled the cover off 4 of the side mounted square chips Q11,Q15,Q9,Q13 are burnt will replacing them repair my amp


that is gonna be the place to start but you also want to check the pc board for burn damage, and test your capacitors. unless you are electronically savvy i would bring it in as you could cause more damage. doesn,t hurt to get an estimate, you can always take it home and do the repairs yourself if you feel up to it.

I have this problem. my bass amp is blowing fuses SWR workingman4004 the problem is that not only burns but also fuses the 4 output transistors (2sc3264) and a resistance R22, and replace them when I was...


I don't have a exact schematic for your amp, but I can give you some hints and suggestions...

USUALLY when the output transistors fuse there is a problem at least one level back and sometimes two levels. Often the driver transistors also get fried and sometimes one stage farther where the bias is regulated for the final amp transistors. A schematic is imperative to diagnose and repair unless one replaces every part.

Next, to prevent damage when restarting the amp, put a 100 Watt incandescent lamp in series with the hot power into the unit. This acts as a current limiter and auto-resetting fuse. The lamp will come on and limit the current while one troubleshoots the amp to find what is causing the current drain.

This schematic MIGHT be pretty close to your unit:

I would expect to see Q4 through Q12 destroyed and maybe a few more components. If transistor Q4 opens, goodbye all the transistors! The 1N4004 diodes are PROBABLY big enough to take it, but all the small transistors probably are damaged or degraded... The high value resistors will survive, but the low ohm ones that can draw enough current may be damaged.

Try to analyze what each part of the circuit is for... I think Q13 and Q14 are part of a soft start circuit. This amp is NOT well protected in case of component failure and MANY that fail in the final stages cause catastrophic destruction.

Use my suggestion for the lamp. Often using a Variac to slowly bring up the voltage is handy, but one doesn't only have one available.

I need a main power supply PCB for my WT323 LCD TV.


There is no such manufacturer for that make. You must give all numbers off the board itself and hope its available. If not, it must be repaired to component level.

Need a circuit board diagram for the SWA1501


not difficult...2 screws on the top and 2 screws on the bottom of the box will remove the amp section. Did you change any components that rectified the fuse blowing problem ? ie. like Q17 - 2SC5200 0r Q14 - 2SA1943 are the main output drivers..

PLANAR 42BK PDP TURNS ON THEN OFF


I have the same problem, with the cover off I used a hair dryer to warm the C18 capacitor then switch the tv on and it works. C18 is located at the top of the power board, thats the second board on the left, it's value is 450wv 330uf. Until I can get the capacitor I leave the back open. Let me know this works for you.
