Love it!



re: 2000X

I got this wonderful stereo as the result of dumpster diving! Can you believe someone threw it out? Well there is an issue, maybe someone out there can help. I'm getting a hum from the speakers. I'm thinking it's 60Hz, typical of a ground loop problem. Still, could be bad capacitors. I know the hum originates in the 'PRE OUTPUT' section, when I disconnect the 'PRE OUTPUT' to the 'MAIN INPUT' , the hum stops. If I connect my MP3 player directly to the 'MAIN INPUT' I get good clean sound amplified sound, but loose the 'PRE OUTPUT' functions (volume, balance and tone, as well as switching multiple inputs).

2000X - FM antenna

Hello, Beware- beginner question.
I am the happy new owner of a 2000x. I was trying to find out how to add an FM antenna, but I'm not finding an owner's manual for the unit, and three rows of input for antenna is more intimidating than I was prepared to face. Could somebody point me to a description on how I would go about this? I'm thinking even a lengthier wire might be sufficient for my purposes, just not sure where to connect it.

Thanks, Ferenc

About 1,5m.wire connected to point "A"(75 Ohm) of FM antenna terminals at back side.

Phono input

Love my 2000x!

My only probom is the 2000x has 2 phono inputs and only 1 AUX input. I'd like to have 3 things hooked up to this receiver--a phonograph, a CD player AND my iPod.

Is there a way to have 2 AUX devices and a phonograph connected at the same time. I dont want to have to connect and disconnect the CD play and the iPod jack cable.

Is there a way I can convert of the phono jacks for use with the CD player or iPod without getting the distortion associated with phono jacks? Can I covert one of the tape recorder inputs to work as a 2nd AUX jack?

Any help is most appreciated!

re: Phono input

Just attach one to AUX in and the other to the tape monitor input. Press in the "Tape Monitor" button to use the other 'AUX input.'

Changing Phono input into Aux. input

Phono 2 can be converted to a auxiliary input but a technician has to do it, or you can use a voltage divider to eliminate the distortion but the sound will have a lot of bass due to the Phono stage equalization.
here is the link:

Forget about the math, use figure #2 as a reference, where R1 is 100Kohms, R2 is 4.7Kohms, Vin is the signal coming from the CD and V2 is the signal going to the Phono input, you will need 1 circuit per channel

phono input using line levels

it requires an inverse riaa network in order to have proper frequency response.

MCM electronics sells one for around $8 US


Sansui 2000X Filter Caps (EC)

I wanted to ask if anyone knows a replacement for the ELNA electrolytic caps used in the power filtering stage of the Sansui 2000X receiver?

I need new replacements / equivalent for:

ELNA 50 V 1000 uF Black - Negative EC
ELNA 80 V 2200 uF Black - Negative EC

Also, Where to obtain replacement capicators?

Thanks for your advise.


Sansui 2000X Filter Caps (EC)

Hi Jack,

You mean the capacitor C003 and C004 2200uF/80V value with the value 1000uF/50V
Both can be replaced with a capacitor of the same value, and can be purchased in stores nearest electronics


Sansui 2000x

I just downloaded the service manual for the Sansui 2000x and it looked fine, but it seems to be missing the schematic diagram. I realize the schematic was separate and not attached to the manual. Perhaps the schematic was not scanned in to the system. If you have the schematic for this unit, can you please let me know. Thank you for your wonderful service.


Sansui 2000x schematics

Hi Ben,

I was wondering if you ever managed to get a copy of the schematics for the 2000x
If not,I will keep looking and upload if I find them.

Do you have a copy of the owners manual you can share?
I picked up a Sansui 2000 yesterday.
Do you know if the 2000 is the 2000x?

Thanks in advance for your help.


Sansui 2000

I have a schematic for the Sansui 2000 which was first manufactured in 1968. Is this the one you need?
