Question about JVC RX-ES1SL Receiver

1 Answer

Very noisy power transformer

Hi all I have the above reciever with about 4 years. I have noticed lately, that when output levels are low as in quiet speech, I can hear a very irritating hum from the transformer( 230v to 6v). It appears to be getting worse. Is it possible to replace the power system with a better one or are their other possible solutions. Regards Dom

Most transformers are bolted but some are just screwed you could probably check to see if teghtening is needed.

Resetting a tripped kitchler low voltage transformer


Model number is not known.
I did not know that Kitchler transformers have a circuit breaker.
Usually they have an override switch.
Did you set the timer to override, what does your product manual say?
Is the transformer humming? Kitchler transformer are supposedly non-audible, but there should be some indicating sound. The humming sound indicates the transformer is working.
Does the unit have photoeye? Cover photoeye with black tape.
Test outlet with circuit analyzer.
Check outlet voltage: if you have 120Volt then output is 10% or 12Volts. If you have reduced voltage, then output is still 10% but might be lower than needed to operate bulbs.
Plug timer into different outlet.
Test output terminals with low voltage tester.
Did you have power outage or nearby lightning strike? Transformers are not protected from surge.
Suggest you contact kitchler.
Kitchler.com website is useless

Kitchler products are probably warranted through the seller.
Kitchler product manuals are almost non-existent.
Scan your product operating manual and parts list into .pdf format and post on web for others to access.

The unit itself is generating too much noise(hiss). some effects are noisier than others but overall noise level is unacceptable. all the product reviews say how quiet this unit is. tried changing signal...


Check that: You are using BALANCED interconnection lines (TRS or XLR) everywhere. Low quality cables can cause or let in noise and hiss.

Check that ALL, and I mean ALL interconnected equipment is powered from the SAME receptacle or power conditioner.

Check that you are not using a noisy source or recording system like the internal audio of a PC for instance.

Short the inputs to ground and see if the output noise goes away. Some effects are noisy because the inut signal after effects gets added back into the output.

You haven't described your setup and without that information there is not much more I can add. Ferreting out noise is one of my specialties. In general your input level should NOT be too small as this leads to less signal to noise ratio due to digitizing noise. Look at the Lexicon specs to find what the levels should be. Without the description of your setup I can add no more...

I believe the design of this results in what you are seeing... Check each speaker INDIVIDUALLY plugged into the MAIN output as plugging into the second jack shifts the tap of the output transformer to the 4 ohm tap which results in a 6 Db drop but now you have two speakers... the apparent level change will be almost unnoticeable.. Do comparision of the speakers individually using the MAIN jack. This is just the characteristics of the beast...

The water level in the machine should be slightly under the heat element. The float you refer to is only for overfill and should not be activated if the machine is filling properly (the water level should be lower than the float switch activation point).

The resistance range on the inlet valve is 890 - 1080 ohms

The machine fills on time and there is flow restrictive washer in the valve, if it becomes contaminated the water level will be insufficient.

Let me know if you have questions.

Hp Pavilion getting no power after relocating pc.


the Power transformer has diferent outputs, +5V,-5V,3V,12V and so on.., but has a standby output a low power 5v to power button function.
Your PC have Power supply Defective,
so your must find a usual spare power supply on the market, compatibilty as 115V input and more of 350W power, to have stabilty.

Too much bass...low end


Hi, have you tried adjusting the "subwoofer level", and or the "subwoofer cut" controls? Every sub I have ever seen has at least the level control on the back. The "cut or crossover" control determines the frequency at which the sub will start to respond. Additionally, you may need to access the appropriate menu on you reciever and adjust the "low frequency effects" (LFE) output level (assuming you have connected your sub to the reciever's sub output jack.

Hope this helps.
