Pre amp to amp

I was told that if I put the output of the preamp (Phase Linear 750 watts) to either of the other to units it would :"fry them". Is this not the case?

Pre-amps don't put out 750 watts. They put out about 1 volt at several thousandths of a watt. I think you are calling a 750 watt amplifier a pre-amp, and that ****** will definitely fry things.

What kind of pre amp do i need to operate my parasound HCA-2205A high current power amp


Any preamp should work. A preamp goes into your system between the amp and the other components which plug into it- CD player, FM tuner, Turntable.....etc. It's takes their output signal, processes it as my be Volume, bass, treble... and then send a sufficient signal to the amp to drive the amp to power your speakers. As long as the preamp output is enough for your Amps input any will work as most will be.

You will need to isolate the fault to a particular stage.
The two large valves are the power output valves and operate in push/pull mode. The next stage is the phase splitter and driver stage. The next stage is the tone control and compensation. The first stage is the pre amplifier stage. To eliminate the output and drive stage you will need to inject a signal at the top end of the master volume control. Touching this point wth a screw driver will inject enough hum to give a strong buzz from the speaker, if this is the case then fault is in pre amp of tone circuity if not. Check screen feed resistors for open circuit (wire wound resistors to screen pins of output valves). Check resistors to anode and cathode pins of phase splitter for increase in value. If the output stage seems ok then isolate the fault further by touching the screw drive to the grid of the valve in the tone network and then the pre amp valve. The buzz will get louder as you progress if the stage is working ok. If not check anode voltages and resistors.
WARNING. dangerous high voltages exist in the circuits. Only ever use one hand when making contact tests, keep the other one in your pocket. If you feel this help is beyond you then please seek professional help.
All the very best from Vintie

This is not a problem with dirty components. There is a semiconductor inside that is sensitive to heat and is failing. This unit should be taken to a service shop before complete failure. It has the potential for frying the output section depending upon the part that fails.

Please seek professional assistance with this repair.

LUXMAN L-85V AMPLIFIER LOW VOLUME


Make sure that you have the turntable connected to the PHONO input. If there is none (I don't know your specific model), then you will need a phono pre-amp. Connect the output of the pre-amp to tape-in or Aux in and the unit should work as expected. The alternative is that you may have the tape monitor turned on. Check that as well.
This unit is old enough to have pre-out and amp-in connectors on the back. Make sure that those are connected to each other. Use standard RCA cables.

If none of those resolve the problem, there is an internal problem that will need a bench to resolve.

Can you please specifiy which Phase Linear model you are interested in? The outputs vary from model to model. Also, is there a specific problem that you are having? Any details you can provide will help us to post more details.

I am not aware of the service manuals being available on line at the moment, but will research this a bit more.

Pre Amp Set up


Get the right cables and plug them in. Pre-amp to mixer to amp. Radio Shack is a good place to buy the wires with proper ends on them.

Proper connection from amp to pre amp.


Hi Jimmy

The output of the preamp connects to the input of the power-amp, left and right channels respectively. Some preamps (like NAD) can have more than one set of outputs, is this what you are dealing with? If you can give me the make and models of the gear then I can help you more... :)
