Question about Amplifiers & Preamps

1 Answer

Volume control is too loud at minimum settings.


Would a resistor added between the wiper and ground make the lower volume settings lower? If so, what value would be a good starting point?

Otherwise, an attennuator between the wiper and power amp section would reduce the overall volume but, what is the input impedance to the power amp stage to calculate the resistor values?

Or, would the cleanest solution be to reduce the overall gain in the power amp stage somehow?

Many amps these days have an IC that controls the volume and other functions such as bass and treble. You need to follow the wiring from the volume control to where it meets up on the PC board, or follow the circuit if the control is mounted direct to the board. As this is on one channel you have the good channel to compare it with. If you are lucky there will be two of these IC's one for each channel. If not then the volume control connections will all go into one IC. Putting a insulated tool on parts of the amp will cause it to buzz when it's on, on each channel. That way you can find the faulty IC. But don't short any of the pins of an IC together.

Crackling noise with my volume knob when i turn the volume

It's probably dust in the volume control. It gets in between the carbon track and the wiper that rotates on the track, or the resistive / carbon track inside the control is wearing out. As yours is stereo there will be 2 tracks and 2 wipers, one could be worn more than the other.
This should give you an idea. Inside Pot

TEAC A-H300 Amp no output

If you still have the following voltages (0.3,44,0) and (-.1,-44,0) then the final stage is not turned on and you will only get low level sound. The driver +/or bias circuits are defective. Disconnect the center lead from each of the transistors and measure the 2 outer leads to ground,. Check the driver transistors for either an open or shorted condition and replace as necessary. Once the driver and bias circuits are working, the 2 outer leads should read +/- 0.5 and 0.

That should resolve the problem. Look for low valued resistors that are open.

Keep us posted.

Carver stereo amp will only play

That should be normal. The main inputs usually go directly to the power amp. If you want volume control, put a mixer with faders beween them... Radio Shack used to have some inexpensive mixers.

Rotel RA01 amp - volume control

Make sure you connected your record player in the right inputs. Better try it to a line level auxilliary input that is sure to pass the volume control. hope this helps..

Volume handle doesn't work well

Yes Mr.dinoza,you have a vr (variable resistor)or the volume control itself has a problem,you need a service center or a qualified serviceman to do it. dodoy
