Quick Luxman R-117 question

Quick answer:

Speaker A & Speaker B outputs are identical as far as specs/load are concerned.😊

The terminals are in parallel, so there is no difference.  The issue is that they probably expect a minimum 4 Ohm load, so that means if you use both at the same time they should be rated at 8 Ohms.

@imhififan @erik_squires Thank you for the responses - I am having relay problems/cutout on channel A, so am going to try B outputs, and was wondering if there is any difference - thanks again!

Hmm they are likely in series with a jumper so you are probably going to see the same issue. Good luck though, love that older Luxman stuff! 

Relays are cheap and easy to replace. :)

@mofojo Ah crud, well i'll give it a try, then look at cleaning or

@erik_squires replacing them, if that's easy enough. Thanks for the help!

Putting the volume slightly above 25% seems to override any problem, but that's just a tad too loud unless I'm really vibing. Volume knob was wonky when I got it, so could be related to that.

And yeah @mofojo it's an absolute pleasure sound-wise, this issue aside!

I had an amp (Onkyo) where the A and B speaker outputs were separate amplifiers on their own heatsinks. Even the circuit diagram confirmed this. You could run A, B, or A+B.

they are likely in series with a jumper so you are probably going to see the same issue.

The R117 uses 4 SPST 16A rated 24V relays, 2 for speaker A and 2 for speaker B. I think the Omron GR2-1A-E-24V could be used as a replacement.
