Question about Denon AVR-3805 Receiver

Potentiometer and output transistors

I am trying to find a generic potentiometer that will replace the square 7mm grey pot with a white adjustment screw, it says 331 on it, no other markings.

Also the two output transistors MN15N and MN15P are blown. I found that the SAP15N and SAP15P are replacements for those, but only place that sells them is Newark and they charge a $15 handling fee.

Anyone know of another source for these parts besides direct from Denon?

Thank you.

    I found out that MCM electronics is one authorized distributor for Denon Parts and had all the items I needed in stock for a fair price and 7.99 shipping.

    In case anyone is having trouble finding these parts the Denon numbers are:

    Variable resistor 331 = 2116131939 $00.47
    MN15N Transistor = 2740196007 $15.97
    MP15P Transistor = 2720157008 $12.58
    3200 Transistor = 2730458904 $00.84

Try sony for the transistors, they use them too, but expect a handling and delivery charge from all suppliers these days. It sounds like a standard 330 ohm preset pot by your descriptions. There are more than a dozen varients to chose from. You will need to compare the lead setup and pitch to get the correct replacement. I use Farnell electronics to mix and match odd replacements. Good luck

What causes a false reading 3 beeps-1 for throttle no good.But if i try the throttle on another pride machine it works perfectly

You may have a bad speed pot. The speed potentiometer is wired in series with the throttle potentiometer. Try testing the speed pot by testing the resistance or simply shorting across it to test. I usually replace both parts for a complete failsafe repair. Hope this helps.

My friends millermatic 175 mig welder burns way too hot and burns through almost everything. Whether the voltage control is turned all the way down or all the way up, there does not appear to be any...

The potentiometer can be checked with a multimeter ohms range. Analogue is best.

I would be surprised if the potentiometer is faulty but you might be lucky. MIG welders rarely use a pot to control the voltage - most often the voltage or power is adjusted in steps by one or more switches and it is the wire speed and current that uses a potentiometer.

I have installed a supermod on my radio clipped d11 and added varible pwr to the delta tune knob it worked fine for a couple of days the varible was touchy now it will key up but will not modulate. i...

  • Why would you cut d11 when you can adjust VR4 and have it sound so much better? When you cut d11 you put that modulation into overdrive. Put that diode back and adjust VR4 for 100% modulation. That is step one.
  • I assume you added variable power from J36. The problem with adding variable power and not switching the pot is that the wires not only have major loss, running to the pot. And two the stock potentiometer tend to burn up if not replaced with a potentiometer that adjust power by itself. Undo this so called "super mod."
  • Start with a 1969 final for better handling of power.
  • Adjust VR4 for 100% modulation.
  • You can pull the ferrite out of the pot next to the final transistor or you can remove j36 and add a 330uf capacitor (black stripe, negative) to the rear and bias the soldier side with a 33uf resistor. Soldier the resistor to the same soldier points of the Capacitor.
  • Adjust L14,L13 and L12 for power.

Speaker output knobs producing crackling sound from speaker

The problem is that the potentiometer that the knob is connected to is dirty. This is a common problem with age, or quality of installed potentiometer. (potentiometer is the name of the component that the knob attaches to. It usually looks like a 1/2" long cylinder)

There are multiple solutions to this problem. The first is free & anyone can do. While the unit is off. Twist the knob back and forth quickly and rapidly numerous times. Roughly 10-15 times will do. This sometimes allows for the connections within the potentiometer to reconnect, and remove the crackle.

The second solution involves some handy work. The unit's case will have to be disassembled, and the potentiometer that the knob is attached to must be found. There is usually a relief hole somewhere on the housing. Within this relief hole one can spray contact cleaner. This cleans the contact within the potentiometer which is the cause of the crackle. Once the pot has been sprayed, rotate the knob like in step 1.

If steps 1 & 2 do not work, the potentiometer will need to be replaced. This work usually needs a professional. If you are handy with a soldering iron, it can be accomplished. Look for any particular part #'s on the crackly potentiometer, and then copy these into a online parts catalog. and are excellent resources for finding parts. Upon finding a replacement, it can be swapped out, and provide the user with a crackle free knob.

As always, make sure power to the unit is disconnected. If you are unsure of electronics, please use caution, as dangerous voltages may reside that can cause personal injury.

Volume adjuster stays on one level can not increase or reduce volume

The Potentiometer/switch (the rotary knob to adjust the volume) is probably faulty. The original is a 9mm B50K panel pot/switch. I'm on the hunt right now for a replacement.

If I can't get one, I'll have repair it using substitute parts, specifically an appropriately sized SPST switch for the power circuit and a regular B50K potentiometer to adjust the volume.

Pot speed and throttle speed beep code is happening. how to get it going again.?

This is a very typical error code when the throttle potentiometer is out of neutral at start up. This is caused by wear or hitting or bending the throttle lever.
In my experience the best way to adjust the throttle pot is to clean it. I usually replace both the throttle potentiometer and speed potentiometer when they fail, cause an error beep, or they have dead spots. You can carefully remove these components by removing the covers and following the service procedures in the service manual. Very carefully take them apart to clean the wiper on the potentiometer with electronic spray contact cleaner (this is not in the service manual; use extreme care and do it delicately).
You can adjust the spring tension on the throttle potentiometer with careful bending.
You can first try to zero out the throttle pot by hand (even it out) and start the scooter to clear the error code. With your left hand adjust the lever left or right and with your right hand turn the scooter on. By trial and error you may be able to get this to work.
In both circumstances you will wind up replacing both components anyway and the fixes I have described are only temporary. Hope this helps.

What potentiometer is being used in rbx 374 bass volume control..because i replaced it with a500 potentiometer but still its not working..i bought yhe bass second hand,,is potentiometers for active pickups...

Yes, active use different value pots than passive. The volume control is LIKELY an "audio taper" which can be either an "A" or a "B" marking as there is confusion about the marking. The resistance is likely around 500K ohms down to as low as 50K ohms. The marking MIGHT be something like 504 B or 503 B or the same with the letter "A".

An A500 pot might be only 50 ohms... That would result in very low output. Again, the marking in the industry is not consistent.

Best bet is to get the part from Yamaha. Go to Yamaha America "parts" dept in California. You can search the phone number with Google.

There is a repetative clicking sound whenever I use the treble on my guitar. what is causing this?

Did you mean the treble control potentiometer (knob)?

This was posted as an amplifier problem, but since you mentioned that the use of the treble (button?) on the guitar is causing the clicking, i would have the treble potentiometer checked first.

It could have a loosely soldered or broken wire on any of the tabs, oxydized slider contacts, bad ground (negative) connnection, possibly dirt or damage on the resistive track inside the pot.

A broken wire can easily be resoldered, but if there is internal damage or oxydation, the potentiometer should be either cleaned or replaced.

In short words - it may be a faulty treble pot.

There are ways to disassemble and clean a potentiometer, but the difficulty of this task may vary and depends mostly on the type and build of the pot.

The other alternative is to have it replaced.

NAD 302 stereo balance problem

I would replace the output transistors of the bad channel and any very low ohm resistors associated with them.
Whilst youre in there replace the electrolytic caps in the power amp section. Caps are cheap and plentiful.
I dont know what the rest of the circuit looks like but there might be a need to balance the DC offset after replacing transistors. and carry many good replacement transistors.

usually trim adjustments are on the controller... not on the vehicle itself.
a potentiometer os a fancy word for dial adjustment. It wont be a metal screw, but probably a metal square with a plastic looking slot that can be turned. usually white or blue plastic
