You should have a lifetime warranty on it . If you are not the original registered owner you may need the original owner sales receipt etc.
Looks like you are not alone with a main board issue ….. see #2 below. I had issue #1 (and a main board warranty fix) below. I took it to a local tech who “ popped the hood” and put in a thin washer/spacer to permit the power switch to “unstick” …. EZPZ fix to the sticking switch when it got warmed up. No problem now .
“ …. There are 2 disturbing problems with the Rega Osiris which I cannot find a outlet for proper constructive feedback:
1. The power switch: After some listening, I simply cannot power off the unit. The power button is stuck and I actually need to pull out the button in order to turn it off.
2. There is a constant hissing/buzzing on the left channel. It comes with intermittent high frequency mosquito-like rings as well. I have cautiously checked and concluded that the left channel is the culprit. The right channel is almost silent.
I have a replacement unit from the dealer and the outcome is the same. This is frustrating for a high-end model from Rega. And the issue is made worse by the seclusion of Rega - Is there anyway to contact them on this? Thanks for the advice”. …”
