Onkyo Integra M-588

Hi, I recently came across (and old dream) the M-588 in Champagne in seemingly excellent condition. 

1) It runs a little hot I think - any experiences out there

2) I am struggling figuring out how to switch between VU Meter Range 1x and 0.1x - not able to find it in the only manuals I have been able to locate.


hifiengine vinylengine have manuals available


free membership, then free downloads, limited to a few per day

this may take you to the service manual I downloaded


perhaps you can find a similar model with meters with explanation of the meters

page 3 ...


The meters switch "automatically" back and forth depending on how many watts are being registered/used (1X for higher wattage and 0.1X for lower wattage).





Sorry, I reversed the 1.0/.1 duties, but assume you got the drift.

I have 2x M504's that run a little bit warm and they've been fine for years. Just curious, what did you pay for that? They're hard to find and worth quite a bit


Ok. That’s re-assuring. I’ll probably take it for a cleaning at my local dealer. 
I paid approx USD1,600 (purchased it in Singapore). No scratches or anything. Only what I guess is common: the vinyl wood needing a bit of glue.
