Pre amp on off switch, sansui g-8000

Have got hold of an otherwise nice receiver, with a flakey pre-amp switch, which makes the unit cut in and out. are these switches available, and is it an easy job to do? is it worth it on one of these?
Thanks for any insite,

SOURCE: sansui g5500 receiver keeps blowing fuse 5amp.

What fuse are you blowing? A fuse in the amp itself, or the fuse in your main fuse box for the house?
If it's the one in the amp, check the speaker wires for shorts, and if thats not it, then it is bad news as stated above.

If it's youre home fuse thats tripping, then you need to consult an electrician to give you another ciruit for your setup. Possible the TV is draining a lot of power.

try turning it off overnight and do a hard reset. Other than that, It is something you should refer back the the supplier and have the unit replaced.

SOURCE: Is this receiver capable of speaker signal output

According to the manual, which you should have:

1st question: No "A" and "B" choice, just one set of Front speakers. Center speaker, yes. It requires a self-amplified subwoofer.

2nd question: In the manual. Select Speaker Sizes, presence, distances and other parameters. Run Test Tone for relative volume of each.

3rd question: Yes, for stereo material only. It has no multichannel Line Level pre-outs.

So you're saying ac doesn't get very far into the unit. THAT should be easy to diagnose with CARE since ac is usually passed unmodified to the fuses and power supplies, maybe through a relay. Get a digital voltmeter and find out where it disappears after getting into the unit.

Can i hook up a power amp to my Nad 7155 receiver and how

If the Nad has pre-amp out sockets that are currently connected to the power amp in the receiver. Then you can sever those link and put the pre-amp out into your Aragon inputs.
Otherwise I don't see how you can connect the amp.

I have a Sansui 2000A Stereo Tuner Amplifies that powers up but has no sound. the fuse for the 220-250V 2A was blown and replaced. The speaker fuses look good. Should I replace them too or is there...

If the fuse was blown on the 220-250 V side, I am assuming that you are in the UK, if you aren't , but are in the US, change the power setting dial/switch on the back to 100-120v and you might be good to go. Also, I know this may sound silly, but make sure that the speaker selector switch is pressed in or set to a speaker set ( A or B). Love the Sansui gear, have many complete systems myself!

Preout section cannot ingage

If you are using a pre out to a sub woofer, you need to make sure that the sub has it's own power amp or it will not work. You also need to go into the user menu and tell the amp that you are using a powered sub. Otherwise it will not turn on the pre amp output

Distorted sounds

The AT-PL120 uses a magnetic cartridge to extract a music signal from the record. Magnetic cartridges all put out a very weak electric signal, and so their output must be strengthened, or amplified, to where it is as strong as the input from, say, a CD player. This amplification is provided by a pre-amp. If your receiver has dedicated "phono" inputs the pre-amp circuits are already in the receiver. If you do not have dedicated phono inputs you must either buy a pre-amp, or buy a magnetic cartridge turntable with a pre-amp built into itself. The AT-PL120 has a built in pre-amp. You can switch the AT-PL120's preamp on or off. The switch is located under the platter at the back side of the turntable. Take the platter mat off and turn one of the platter's holes to the back and you should see the switch through the hole. If you push the switch to LINE OUT the preamp is turned on and the turntable sends an amplified cartridge signal out the cables which MUST be connected to a receiver inout suitable for a CD player (a "high level" input). If you push the pre-amp selector switch to PHONO OUT the turntable sends the weak unstrengthened cartridge signal out the cables which MUST be connected to the receiver's dedicated PHONO inputs so the signal can be amplified with the receiver's own pre-amp circuits.

If everything is set wrong (i.e. LINE OUT (pre-amp on), and connected to phono inputs) you are applying two steps of strengthening to the turntable's signal which is too much. The resultant sound will be garbled. Try not to do this!

The other way to do everything wrong is set the pre-amp switch to PHONO OUT (pre-amp off) and connect the turntable's cables to a high level input. If this happens the turntable signal receives no amplification and the resultant sound will be thin and weak.

Initial setup no sound from my end

When setting up receivers or amplifiers,
Following will help to determin or correct the Problem.

1) Do not plug any sources into the unit but power cord. Then wait for 0~5 second while an ear on top of the unit. See whether the clicking Sound can be heard. ** This will tell whether the actual unit has problem or not in Power Supply or in Power Amp Circuit. If it clicks, then The Amp/Receiver is partially OK. In other word, the problem may be something else. If No Clicking Sound, then Definitely there is Problem. Meaning The unit must be serviced by Professionals. ***NOTE: This applies to Modern Receivers or Amplifiers (I would say, the units manufactured after 1980.). Vintage Units may not Apply.

2) Make Sure Speaker Selector Switch for "A" is on.

3) If Above is met (if Clicks), By visual inspection, See if the Tape Switch (Source Select) or Tape Monitor Switch is on or not (Usually Tape 1 or 2 indicator lights). This switch mu be off!! or set to tuner.

4) Many of the receivers or Amplifiers has a Loop called "Main In/Pre Out" at the back of the unit. There must be horse shoes type pins in them. Otherwise it will not Sound. (Some units has a On/Off Switch near by those jacks and have to be on position).

5) Some Units has so called "External Processor Loop" similar to #4 above and the Switch is on the Face fanel usually. (Must be Off Position)

After the Steps #1~#5, if Everthing is Corrected, then the tuner should Sound (Unless there is proble with tuner).

Now Plug in one Source at a time.
****NOTE: When plug in Tape Deck, Make sure to plug in properly. Out of Tape Deck to Play of Receiver, In of Tape Deck to REC of Receiver. Otherwise (if Reversed), the Sound will be muted or No Sound Will Occure.

It sounds like there is a transistor that is breaking down because of heat. With the unit placed away from the amp, there is less heat. This unit needs a quick overhaul. If a tech can reproduce the problem, the use of a "freeze" spray will make finding the problem transistor easy. Figure on $5-$10 in parts plus the local labor rate for the total repair.

I own a classic Sansui intergrated amplifier (AU-717). It has a short in one channel. At low volume, the sound shorts out. I've had this unit for about 20 years now. Otherwise, it's a great product!

Hi mellemcee

Cool amp mate, and becoming collectable now to. Sansui amps from the era where the best in the world of HiFi. iT may have lost bias control to the offending channel, it may have dirty source switches, tape monitor switch, or even speaker switching. The speaker protection relay may also have a dirty contact, will usually burst back into life with a quick rotation of the vol control. Can you pin the problem down a little more with the info i have given you, try all the controls to see if it impacts on operations, you will need to fix those problems first. Low bias would make that channel sound distorted at low levels also. Is this what is happening to you??
