has anyone had any problems w/ Jasmine phono LP2.0



One of either channels stops working.
I have already returned the unit back to China twice
They have replaced the unit and now it's gone down for the third time. I contacted a local tech in NYC and was advised
it probably would not be worth having the unit repaired.
Has anyone else had this problem? Can anyone recommend a tech
here in the states preferably in the New York area

Antnee, While you are having the FETS replaced, upgrade the output capacitors to Jantzen Superior z-caps. They are a big sound improvement on an already excellent phono.

The caps are inexpensive $25 for a pair of 1UF from Parts Express.
The improvement that the Jantzen Superior z-caps made to the phono also accomplished a similar feat when I replaced the coupling caps on my speakers for the tweeters. It cost a few hundred dollars. But it was a marked improvement.
I have had my Jasmine for a number of years with no issues. Nor have I read of others experiencing problems. The circuitry in the unit is quite simple and solidly constructed.

Like Nandric implies, I wonder if you have an issue elsewhere in your system?
Nandric, Are you suggesting that changing the output capacitors will NOT improve the performance of the Jasmine?

If you have not heard the modified Jasmine (with upgraded output capacitors), you are not in a position to comment for or against.
Nandric, You can lead a horse to water, but you cannot make him drink it.

For those interested in reviews of various capacitors and their sonic characteristics, try Humble Hifi Capacitor Tests. Below is the link.

I have the older Jasmine and I have to place my ear about a foot away to hear a faint hum. When I retreat a few feet it is quiet.
Dear Nandric, I am pleased you gave the Janzten Superior z-caps a try and provided the feedback. The silly thing is the enormous performance upgrade for €25. The Jasmine is a real gem. I wish you all the best.
Keithtexas, I have modest skills with electronics. So, take pictures along the way as you disassemble the unit. Note the location of the loading (ohms) switch before you remove the knob. Remove the locking nut of the switch for the cartridge MM/MC.

Before accessing the PCB (printed circuit board), desolder the DC 24 V connections. Purchase finely-braided desoldering wire. This is the best at wicking the solder. Make a drawing of the wires and their locations. Desolder the ground wire.

From their I believe you can now unscrew the PCB. The output capacitors are easily identified. They are the largest and are labeled 1 UF. The replacement caps will be much larger. Conform the wires to fit in the slots. There are extra holes for longer caps. Use them.

Avoid overheating the connections.

Reassemble the unit and enjoy. I prefer to use silver-bearing solder. Radio Shack carries it as well as Parts Express.

Also, review the Humble Hifi Cap Test website for even better rated caps. The Jantzen Silver Superior Z caps are even better.

View some of the images of the Jasmine using a Google search.

Dear Nandric, Thank you for the note about the wiring upgrade/limitations. I wish you all the best.
