Help! Naim NAC72 lost right channel

[RyanSoundLab]

The relay on the 525 has a single coil and two sets of contacts. Since it switches one channel OK, the coil system is working. It's just bad contacts on one channel inside the relay and there's nothing you can do except replace the relay. A suitable replacement looks like Littlefuse # HE722A1200 or try to find a used 525 on ebay?

Just correcting the last two posts - the board in question is the 325 not the 525.

The 325 is as rare as hen's teeth on eBay.

Oops. Correct - it's a 325. The relays are around $2 from Mouser and others.

Super, Kit, thanks for the Suggestion of a suitable alternative - i was having no luck at all! I

found a HE722A1200 on eBay for €1,70, so let's see what happens next!

I am being a bit cheeky at the Moment and listening with the board bridged, until the relay arrives (being very careful about turn-on order). I am still bowled over by the RSL boards by the way - i was dreading having to Switch back to my Nait 2 as an emergency measure!

Regards
Matt
