A few folks are liking the AD826 op-amps so maybe worth a try too, you can easily change back to the LM4562 if it doesn't suit

Ha, you are obviously not aware of my track record leo

cheers though

so where to get these electrowhsits then? And what's the best option

[Gazjam]

That's not entirely correct, although a little trickier to get hold of. In fact I'm looking at one in front of me now, purchased from Parts Connexion,

ELNA-72734: 4.7uF / 50V, RFS Series, 5x11mm
http://www.partsconnexion.com/capaci..._elna_rfs.html

Still waiting for the Murata's to arrive...

Ah ha!
I did not know that....

Wonder why they are hard to get, interesting they are not on the Elna datasheet over at Hificollective.
Ah well, without knowing what the wee beastie does I wont worry about it!

*EDIT*
Just ordered one!
Dont want any wee niggles at teh back of my mind if I can help it

Not ordered from them before, whats the delivery time like from Partsconnexion then?

Pretty good, usually just over a week.

The guy (post 26) on here may have a couple spare http://theartofsound.net/forum/showt...?t=6356&page=3

The op-amps are in sockets, as long as your careful making sure ALL pins go into the sockets and the op-amp is NOT reversed its not that hard to do, use something like a small flat blade screw driver to prise up the Lm4562, no soldering required

[leo]

But what does that extra cap do?

I'll have a look in a mo

Just had a look under the board, the cap looks to be part of the flip-flop IC on the set pin input, probably part of the input switching

TBH I don't think you'd gain much upgrading this cap, no harm in trying it though, I'd stick with the stock value

The bigger cap near it would have much more influence

[MartinT]

Thanks, Leo. No point in changing that at all, it's probably just switch bounce logic.

As for the bigger cap, already done

[StanleyB]

It's the timing cap for the standby button. I don't think switch on/off will sound any better with a more expensive cap, but I stand corrected..
