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.

Hi geoffflaw

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.

SOURCE: I am fixing a sansui

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.

Radio will not hold sirius signal have to keep getting it refreshed

does it hold any memory, ( i.e BASS / TREBLE settings etc...?)
if not, pull the head unit out & swop the RED & YELLOW wires over, either by cutting them and re joining them red to yellow & yellow to red, or by pulling them out of the ISO block & switching them over..

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

Bought some speakers, they're big and heavy but they don't have any indication of what ohm they are, i connected my turntable and all i can get is a high pitch noise from the speakers and no audio...

most of the speakers are " 8 ohms " ..the very old German made ones are 4 ohms only ...

which RCA jacks did you connect your turntable to Receiver ?
if "phone" ,it requires without "PREAMP" output from turntable.otherwise you will ruin the circuits in Receiver and make high pitch sound.....

Try with any other input on the receiver (i.e AUX.) and test it...
unless your RCA cable broken it should work can try with another cable..and remember to make a solid ground connection between turntable and receiver as is a must.....

Take care and if it succeeds please Remember to rate/vote and give me 4 Thumbs Up
for Helping out the Community :)

Hope this helps!

Twice now my Pioneer VSX-819H has shut down. Can not get any power to it. The first time I'm sure the phono pre-amp caused a surge. I no longer have it hooked up. The servicer said nothing was wrong and...

I found this for the VSX918, 818. Perhaps it's similar.

The power does not turn on. • Disconnect the power plug from the outlet, and insert again.
• Make sure there are no loose strands of speaker wire touching the rear panel. This could cause the receiver to shut off automatically.
The receiver suddenly switches off and the power indicator
• After about a minute (you won’t be able to switch the unit on during this time), switch the receiver back on. If the message persists, call a Pioneer authorized independent service company.

Resetting the main unit
Use this procedure to reset all the receiver’s settings to the factory default. Use the front panel controls to do this.
1 Switch the receiver into standby.
2 While holding down the ADVANCED SURROUND button, press and hold the
STANDBY/ON button for about three
3 When you see RESET? appear in the display, press ‘
ST –’. OK?
shows in the display.
4 Press SOUND RETRIEVER to confirm.
appears in the display to indicate that the receiver has been reset to the factory settings.

How to install bose 901 eq to my pioneer vsx-1019ah-k

This works for all models of AV receivers when you want 901's as Front L&R speakers..

Get yourself a nice separate amp, draw the Front L&R pre-out signals from wherever you can find them. On many, there is a pre-amp out for every channel in case you want to run external amps for any channels. That is how my old Pioneer VSX-36TX is equipped. For others, you may have to borrow the signals from a typical Tape- or Adapter-Out RCA pair. Just remember, AV receivers disable digital inputs as soon as you switch in a Tape Monitor, so choose one you won't have to switch IN. The signal Out is always there regardless of the monitor state.

Patch the Active EQ directly off that point (Amp In from the receiver, Amp Out to the new amp). Run all the speaker level settings on the AV Receiver and rock on.

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.

No sound from my record turntable into my computer.

If you're certain there is no sound going out of the TT...

Setting the Pre-amp Switch
For increased flexibility of use, this turntable has an internal
stereo phono pre-amplifier. The Pre-amp Selector Switch
is located under the turntable platter, in the rear-center
(Fig. 1). If the system amplifier you are using has a PHONO
input, set the Pre-amp Selector Switch to the “OFF”
position. If your amplifier does not have a PHONO input,
set the Pre-amp Selector Switch to the “ON” position and
connect the turntable’s output cables to the AUX or other
high-level input on the amplifier (described later).

Turntable operates, but no sound at all
1. The stylus guard is still in place.
2. The tone arm Lift button is pressed in.
3. Amplifier controls set incorrectly: wrong input selected,
tape monitor on, speakers switched off, etc.
4. Check the stylus on phono cartridge for correct placement.
Refer to the instructions for replacing the stylus
on page 5.
Turntable operates, but no sound, or sound not loud
1. If the turntable is connected to an AUX (high-level)
input: The Pre-amp Selector Switch may be set to the
“OFF” position (phono-input level).
2. The input gain of the amplified speaker or similar
device may be too low.
3. The stylus assembly may not be fully seated in the
cartridge body.

You could also isolate the problem to either the TT or the PC by trying the TT on some other sound device like a receiver. Make sure the PreAmp Selector switch is ON and plug the TT into any AUX, CD or TAPE input.

I have a Harman Kardon 700 Series amp/pre-amp/tuner system that I want to get repaired ( an HK 770 Twin Torroidal Ultra Wideband DC Amplifier, a matching HK 725 Pre-Amplifier, and a matching HK 710 Tuner)...

This will take a little homework on your part, but parts for this might be available. I don't kow your model well enough to know whether or not the power switch is generically available. Any possibility you can post a picture? Manufacturers are only required to maintain spare parts for 5-7 years after they stop selling that model. If the part is generic enough, other distributors will carry replacements. If all you need is the power switch, you stand a good chance that a replacemetn is available.
Keep me posted,
