Murata regs + Caiman = Problem??

Dave - I swapped all my electrolytics for Elna Silmic IIs.

Thanks. It sounds like you have almost the exact same setup as me with the exception of the Gator. Would you consider trying out a Gator if I sent you one? I have a spare. It would be interesting to see if you encountered the same noise issue. I'd obviously pay for the postage both ways. Cheers.

Sorry Dave - I removed the two board sockets and hard-soldered my passive caps in place (to retain the muting relays). I reckoned I had reached the limit of Caiman performance and have been happy with it ever since.

Ah, no probs. Thanks anyway. Back to the drawing board.

Dave,

I replaced all mine with Elna Silmic II as well. I did it all at the same time. Gator I have fitted was one of the first batch made if this is any help.

This is how mine looks, with op-amp board sockets removed and AuriCaps hard-soldered in. Regulators are Dexa, reservoir caps are Panasonic film, all other electrolytics are Elna Silmic II. It sound superb driven from a SuperTeddy set to 16V.

great pic martin,

I've ordered a set of the Dexa's to replace the Murata's

+12 Volt - DEXA-70911
+ 5 Volt - DEXA-70908

and your pic is a good help to install them.
Daft question though?

I've not looked into it yet, but off the top of your head which regulator is the 12v and which is the 5V?
I'm sure I can find it out easy enough, but just wondering if you know off the cuff?


thanks.

[MartinT]

As far as I can remember, the one at the back is the +5V for all the DAC circuitry, the one near the front is the +12V for the op-amps. But PLEASE CHECK before going by my memory.

[Gazjam]

sure, will do.
Not wanting to quote you...just getting an idea!

thanks.

I'm pretty sure that's correct as well.
