I still think he needs to try a different preamp. If, as he says, switching preamp off and on cures the problem......
...yet switching the preamp's inputs?? switched the problem to the other channel???
Wish I could get hold of it (not practical now, even if he lived in the same town of course).
I reckon he's fast approaching the point where he should get the lot back to the dealer whilst still under guarantee - last resort option though.
Sorry for misleading. So when i flipping records i don't turning off preamp. I do that only in one time case, because one channel was off as usual.
Now this might be very relevant.
My RB300 arm has fixed signal leads and one channel became intermittent where the cable entered the moulded plug (despite no mistreatment from me, but due to thin and inferior cable).
When I looked at pictures of the RP8, I saw no sign of a captive lead. Because of this (and the the high price of the RP8) I had assumed that it had RCA sockets and no fixed signal lead.
I would hope that your cable isn't as thin as mine was....but it might explain a lot.
Is it possible for you to show us a picture of the lead and its plugs?
Sure, but when unplugging cable and plug them back problem disappear for while. Weird really, I tried disassemble cartridge for example, clean contacts etc. Even change stylus force, it helps for 3 weeks, but problems comes back.
I was convinced due switching RCA cables the problem is in right channel on turntable cables. When i turn off and turn on preamp i'm not sure at all.
I don't believe they find that is something wrong, even if i describe the problem, may not reveal itself. I have listening session every day and issue occur after 10, 14 days. So basically, i'm screwed.

No you're not. Take them back and tell them it's unfit for purpose and insist they test everything.
Well done with the pics.
Yours is indeed a much more durable-looking cable than on my Rega arm - so not as likely to be intermittent (but that doesn't mean it isn't!).
If it is, it could be that a simple repair at the RCA plug end is all that's required.
Even if you're handy with a soldering iron and capable of rectifying it yourself though, as previously discussed, it's not your responsibility, while still under guarantee, to rectify faults (and you could be deemed to have invalidated what guarantee you had left).
In view of the amount you spent - and not least the fact that the dealer refused to loan you a preamp (to trace a problem that he should have been sorting!) it must be time to get the lot back and use him for your guarantee repair.

I think it is coincidental. The slightest movement might have (temporarily) cured any internal cable break??? (my cable was broken within and very touchy).
Well it could be faulty wiring in tonearm, but i doubt that, because turning off and on preamp, problem disappear. If is preamp related, i have plenty time until guarantee expired. If is turntable problem, wel i have two months before expiration. So i try different cartridge without preamp.
How can you do that?
It's a MM cartridge that you're using, with a MM only preamp (no MC input) have I got that right?
No it's MC cartridge with phono preamp, i have plenty MM cartridges and built in phono in amp. 🙂
If swapping the RCAs round causes the problem to switch to the other channel you have isolated the problem to the TT or am I being particularly dim?
Swapping to MM will at least confirm the tonearm wiring is OK, in which case the MC is the likely source of the problem.

I've done that, problem move to left channel. Logic says yes it's right RCA channel, but when powering preamp of and on again problem disappear for while. I don't believe it's MC cartridge problem related.
