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

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.

I have one thing to add - if your PSU is a separate unit, like mine that I use for my P5, I was told when I purchased it that it will function better if it is not turned off - I always leave mine on, and have never had any problems with it.

Looks like reversing (reseeding, but I tried that before?) the power cable between the TTPSU and the RP6 fixed my problem. I think the rega right channel ground was not right somehow.

Scott, glad you got it fixed! I still don't understand how a power supply can affect the ground on an isolated tonearm?

I've seen many things in all the years I was in the high-end audio business, so really nothing should shock me. I'll add this to my collection.

Thanks for reporting back on the cure...
