@agbrace What do u mean u hear a chime ? Can u explain that chime sound you are hearing coming through the speakers? I have owned the Ref 5se , the Ref 6 and now the ref 6SE. I was using a Krell FPB 600 amp now I am using the Audio Research Ref 750s. I have NEVER heard anything but dead silence
ARC Ref 6 Tube Microphonics
Hi All, I purchased a used Ref 6 preamp a few months ago, initially everything was fine, tube hours indicator said ~950 hours but not sure if that was accurate. After about 50 hours of use, turning the volume past 0 and the mechanical relay kicks in, a chime is heard coming through the speakers. I assumed one or more tubes had become microphonic. I replaced all tubes with new ARC select from Upscale, 7 Sovtek 6H30Pi, 1 Sovtek 6550WE. I let it warm up for a few hours, turned volume past 0 and the same chime is still there. On the positive side, the SQ improvement was immediately noticeable and outstanding, I love the preamp in my setup but the microphonic chime is annoying. ARC service said that some chime is normal but it still bothers me. Any advice? Ignore it? A new set of tubes direct from ARC? New tube rings? Send in to service? Thanks.

@mulveling I Just now checked out your system. Very nice 👍. I too had the Ref 5SE. Bought that used. Sold it for the brand new Ref 6 last year from my ARC dealer. And had it upgraded to the Ref 6SE. Got it back in June. And yes. It took about 2 weeks. Did u have your 6 upgraded or u bought it new ? |
@agbrace definitely not normal. Call ARC and explain it to them. If u do send it expect a long wait But they will tell you to ship it when they will be getting close for your repair so at least you will still be able to use your system If you want to. |
