Luxman LV-117 volume potmeter

It's a stereo linear pot with center tap for "Loudness".

Hi imhififan1,

I read your post probably over a week ago, but just couldn't find time to get into it. Totally should have thanked you right then for your post though. Sorry.
Due to extended duties on inland shipping I still haven't found time to explore the center tap loudness issue, but I'm pretty sure my Luxman has a dedicated loudness button ...
Hi Greorge,
Same deal here. Actually have been exploring what pot version would physically fit my amp, but didn't open up my Luxman LV-117 yet.

Best regards to both of you.

It’s almost impossible to find a 150KB stereo pot with center tap, if you omit the loudness control, the ALPS RK27 100KAx2 pot recommended by georgehifi should work. Or you can use a 23-position 2 deck switch with 22x6.8KΩ resistors in series on each channel to make it to a 150KΩ linear stereo stepped attenuator with center tap.

Hi imhififan1, thanks again. I hope to open up my Luxman (again) the coming fortnight.
