I have solid tantalum on the outputs of the offboard regs, then I've wired to the chip supply pins with 470uF NX on digital and FK on analogue. The skip only happens once an hour or so and I've had the lid off a lot lately, so it might just as easily be a dry spot or dust on the runners. Guys, with servo/output PSUs and now a Flea on the DAC, this month has been huge. What next? Servo or decoder?
P.S. - It's like a Christmas tree in there now with 27 LEDs.

I fitted my DAC clock. It worked first time. It sounds wonderful! The difference is immediately obvious, even from cold. Thanks Ray and Brent for making this amazing mod accessible to lazy newbies like me!
Hi Ben,
That's great, i'm glad you like the result! Next thing? The DOS of course!

Servo clock's installed in quick succession to DAC. Player sounds so good! Huge leap in realism. No nasty surprises on my grungy 90's favourites, but on good recordings the Fleas have pushed the player into a new territory that doesn't sound like anything I've heard. I would believe it was a new format. There's new treble detail, better defining voices and cymbals, but the overall presentation is smooth and lifelike. Skipping seems gone too, oddly. Sod the display for now - screws are IN.
903 and 904 are the psu decoupling caps for the opamp. These will already be out of circuit if you do the above. The links I identified remove the +/-12v psu to the opamp and it's decoupling caps (903&4). As I say, take a look at the service manual, it's all there. We'll help you to understand it ;-)
Personally I would always go for a 63SE or KI. They can be pushed much further.
If you do get a 67 get the SE as the chassis is better.

Seriously, the wife described the clock upgrade as "Lasik for audio". That's big news. I've been modding for about two years now and this is the biggest jump ever. The best thing is that everything sounds good still - I'm listening to Soundgarden 'Superunknown' right now, which I love dearly but is horrible quality. It sounds about the same as normal. Better recordings have jumped a million miles. I've done mods previously where treble has been enhanced and it's been ugly, but this is more like an increase in resolution. The mains hum has got even worse though; it's audible at 12 o'clock on the amp. I really need to sort it out somehow but otherwise I'm loving the sound right now so much.
