Rega TT-PSU drops right channel

Hi everyone. Recently my RP6 starting dropping the right channel as soon as the needle hit the record. My routine is (with the TT-PSU powered off):

- place the record on the platter after a nitty gritty clean
- power up the TT-PSU while giving the platter a nudge
- clean record with anti-static carbon brush
- needle drop

First I thought a tonearm wire was loose on the cartridge or something along that line. But, if I switch the TT-PSU to 45 and then back to 33 my right channel works just fine. I know Regas ground to the right channel. Could something be wrong with the cable between the TT-PSU and the table? TT-PSU malfunctioning (I think it is still under warranty).

Thoughts / recommendations? TIA

@mofi,

My new routine is:

- put on record after cleaning
- turn on TTPSU (usually at 33)
- switch to 45 on TTPSU
- clean record with carbon antistatic brush
- switch back to 33
- needle drop (first time tonearm, cue has been touched)

I've never had a right channel out problem with the above order of steps. I almost always get the right channel out problems if I do not do the 3rd (and 5th) steps.

My dealer has told me in the past (before this problem started) that Regas ground to the right channel and do not use a separate ground wire. Is this achieved through the tonearm wires right to the RCA male plugs or is the TTPSU involved in the right channel ground?

Scott, the ground wire for the tonearm is soldered to the inside wall of the arm tube, (well, on the old style RB250/300 series it was anyway).

Why don't you try to call Rick at Audio Alternatives in Fort Collins, Colorado. He is not only a master Linn turntable guru, but has sold Rega longer than probably anyone in the states. Maybe he has encountered this and will know how to fix it.

Please let us know what you find out.

I had a Rega 3 or 6 (don't remember which) which cut out on one channel too. It was the cable running through the tonearm that caused the prob. Don't know if this helps or confuses.

I love Rega but their "QC" is lousy.

Have you tried playing a record without the TT-PSU ? Disconnect the TT-PSU and plug the table with its original power cord into the wall outlet (or your power conditioner.) How is the right channel now ? If all is well, then your TT-PSU is defective and should be replaced.

Hey .... I just realized, after posting my above comments, that your RP6 may not have its own power cord and you may not be able to bypass the TT-PSU.. With my P3-24, the TT-PSU was an addition, and although it makes the table better in many ways, it's not required for the table to function.
