BTW, I have crystals available at $5 shipped. If someone needs LM7808 reg those are available as well; no BGs though.

I would be very happy to buy an oscillator from you Daniel. Oh and a lm 7808 also

I`ll Pm you.

Guido's clock and dedicated PSU worked GREAT for me in my Wadia and also in my Audionote dac 3.

I have still a Guido clock and PSU lying around but must admit that I did not use it yet in my Pitbull...so I cannot comment..

Since the Trichord worked miracles for me it probably is a happy marriage in my set-up....for me it does not affect that beautiful analog . and I do not have the drive to exchange
for experimental reasons...since I am nearly 24/7 busy with the piTbull's other "shortcomings".

To put things into perspective again..I think somebody else on this forum (a polish friend) used the Guido Tent clock/psu
in his Shigaclone and is very satisfied...so in the end it all depends on taste and set-up etc. etc...

Advice: Implement something and listen....
....since it all comes down to that same old story...

Peter I'd like to buy a crystal from you as well.

It`s all a matter of taste ofcourse Erik. And implementation will probably have a lot to do with it also.

I did try the clock with a separate psu, and got more or less the same results.
As for the midbass that has vanished, I wonder if anyone got that fixed... I know I can`t live without it. Perhaps a small tradeoff for some, to gain resolution and space.

I’ve just tried (in non-blind test , extensive test with independent pair of ears planned for this weekend) both quartz and external clock setup.
My observations: clocked version in better in: overall resolution resulting in better 3D, sources’ localization, presence and indirect sound. Cristal-based setup provides warmer midrange, which might be considered as better musicality, but with grained highs and a bit boomy bass, which with clocked setup seems to be shorter and better controlled with similar deepness.
Looks like clocked clone is more transparent and ads less to the original signal. Since at this stage of development I use my backup ss amp, with my basic AN tubies a bit clinical sounding will get some humanity touch in midrange.
If somebody reports better sounding with cristal than with clock, I’d advise to try 5/8V separation. Having several months of experiences with this funny transport I can say that that’s a key.
My current clone is supplied with two separate 5/8V PSUs with separate regulators and trafos, with limited tuning as for caps at PCB. It eats easily all four previous versions with single PSU and different caps variants.

Andy,

Can you clear up some of the confusion, for some of us, about the correct way to connect the 5v supply? If i am correct you:

- remove the jumper 5A to 5B as pictured in post #17

- leave Q902 in place but cut the trace going from the collector to the +ve side of C916. See pic in post #1601

- feed the +5v to the +ve leg of C916.

Regards,
Dan

Dan,
what I've done: removed Q902, cut 5V track somewhere close to C954 and put LT1086CT5 directly to PCB in the C942 place, additionally connected C942 ground with main ground of 8V input.

brgds.
The purpose of of cutting a trace for C954 puzzles me. Please refer to the accompanying schematic.
