Very nice!
Very nice!
Thank you for your suggestion, i do have the manual before i bought it, and yes from HiFiEngine.Your 1180 has the contour control that is used to compensate for low level listening by boosting the bass. It may also boost the highs some, too. So if you are comparing the amp sound, be sure that the Bass, Treble, Contour and Filters are all set to their center position (Bass, Mid and Treble) or off for the filters and contour.
Then you have the additional control of where the Bass and Treble 'turnover'. The lower bass number will be just deep bass and the higher bass number will include some mid-bass boost. Similarly with the treble control, the higher number will be just the highs and the lower number will include some upper midrange in the boost the control does. These are just adjustments of the audio that the Bass and Treble will do.
If you don't have the manuals, they are available on Hifiengine if you can register and log in. JaS has been keeping registrations less than easy since his site keeps getting bombarded by multiple registrations requests from the same person, bots and all sorts of other crap, probably trying to steal his info.
If you aren't a member and can't register and need the manuals, the Service Manual is on the akdatabase site and you could ask for the owners manual here on ak and maybe someone would email it to you.
Knowing what all the controls do will be helpful as you adjust the sound to what you like.

How do you rate the 1180dc vs the PM750DC?
Since i did not have chance to listen more than 15 mnts, i still not know how it sound. The room where i fix things , i use Wharfedale speaker 2 way and very small. Actually it is surround speaker. After i found the disconnecting audio line between boards, then my power switch is broken. Too many trouble i get. So i make it temporary "always on". Then i put them back together, put all case, faceplate. Then i move to my main room (living room), just aview minutes, then again one of the channel is missing. Im just too tired to fix them right now, while im still waiting the power stwitch from AliExpress.How do you rate the 1180dc vs the PM750DC?
Are they the same line or does the PM/DC line show a definite lower quality?
And why would you want all those sliders? Even the sliders on the 70's Marantz gear can be a pain. Drop outs, scratchy, staticy, etc.
They can be cleaned and lubed like a standard potentiometer, but if one fails, it's a big pain to find a replacement. It's much easier to find a modern rotory pot as a.replacemwnt if needed than a slider.
