So BNC is the more logical choice.
just put 'em when you're finished with tweaks

if that's ever .......

For what it is worth, I have been very happy using the Canare RJ-RU or RJ-R connectors. 75 ohms phono. Also can't tell much difference between Canare cables and others. Michael Percy and Markertek would be US sources.

Thanks for the explanation.

The cable is fairly flexible - about the same flexibility as any old standard solid-core coax really.

Just been looking at my board, and the bridging cable on Okapi's PDF between the + pin of C916, to JW906. I'm having trouble tracing this on the circuit diagram - does this bypass C952 by any chance? (therfore making my 'upgrade' of an Elna Silmic 470uF in this position a waste of time?)

Thanks,

- John
Hi John, as far as I know, the the bridging cable isn't necessary and bypasses nothing.
It is only needed if you break a track when removing the smd cap under the heat shield, (which I did )..

I tried to fit some resistors previously and ended up with a lot of buzzing for some reason.

Can I just check that R1 goes from the board to the centre pin of the BNC and R2 intersects R1 and goes to ground at the board end and the BNC (i.e both ends) ?

I just checked the bestbuy.ca site and it looks like the

local Best Buy stores as well. (The Toronto area stores
seem to have them.)

Dennis
Thanks for the heads up. I went to my Whitby Bestbuy (just east of Toronto) and picked up my RC-EZ31 yesterday.

Regards,
Dan

Connect ground at the board to ground at the BNC. Connect R2 100R, between centre pin and ground of the BNC. Connect R1 300R, between d-out at board and centre pin of BNC..Think that's right..

Audio1st: I'll try desoldering that bridging cable on one end and see if it all still works then. I had a hell of a time removing that SMD cap, so it wouldn't surprise me if the track was damaged actually

Has anyone any educated guesses as to a 'perfect' value for that C906? JVC use 0.1uF. Sanyo recommend in their test circuit 0.068uF. However they they go on to show a sample application circuit (using a LC7822E microcontroller chip) and that capacitor is then listed as 0.22uF !!! AGHHHHHH!

I have some Wima 0.068uF FKP 2 (PP film) which I shall try in this position and record my results.

Just installed the 0.068uF cap in the C906 position. Initital impressions are of a bright sound (which I expect will calm down after a few days burning in), but extremely open - panoramic soundstage. Hyper detailed as well.

Tried disconnecting that bridging cable, and the unit was a dead as a dodo. Reconnecting it and I had power again.
