Default Now gone ...

These are now taken, as best I can tell. eBay page says 5 are available, but I tried six times and paypal says merchant has stop order in, so this stops the transaction from completing.

Default Sanyo SF-P101N

Folks,

The transport/laser is a Sanyo SF-P101N, which is available on Ebay from a number of suppliers complete, or available as just the laser pickup assembly. Prices range $12 to $30 USD.

I bought 3 of them for backup parts awhile back, but a word of caution.
Check for binding of the laser pickup assembly on the guide rod and stamped frame by turning the laser pickup assembly drive motor by hand...the laser pickup assembly should move very smoothly with no binding. One of the units I received was binding on the guide rod due to misalignment of the 2 cast in plastic laser assembly through holes that slide on the guide rod. Some careful lapping of the through holes to increase the clearance fixed the problem.

LA6541, beside BTL drivers have a 5V regulator. This regulator will perform a power low and reset of LA9242 and LC78601 at very new CD reading. To separate 8V section from 5V you need to use regulators who can be enabled/disabled via a dedicate pin.
We have tried this with unsatisfactory results.
Also, using batteries, due their intrinsic chemical noise, which is in high frequency domain, IMHO are not recommended.
What I recommend is a supercap, who can be charged between each CD load.

Regards,
Tibi

As far I know 75 ohm is the standard. As already mentioned by uncle_leon, LC78601 do not mention anything about chip output impedance.

Is any of those identical to the one offered here, or can serve as a direct substitute?

Rats, I got one too. Have you tried to drill it out? How much interference is there?

Default simple puck idea

the attached file is a crude drawing of the puck i plan on making. it should be easy to do with simple hand tools (granted you need a reverse tap/die).

Joshua,

The SF-P101N CD Mechanism is the same unit you will be getting in the group buy. See past below post from Tibi below...

Oh, and while I know this will be of no real use to virtually anyone else, would anyone know just what it would take to fit a ST glass output to this design? I have two DACs (EAD and Wadia) and both have the ST glass input. Right now I consider that superior to others using my current transport. In my dream for this DIY project I'd love to be able to have a quality ST output available.





Yes, it is the same mechanic.

ST glass output it is an option I´ll consider.
Maybe it will be another separate board with reclocking and AES/EBU, S/PDIF, Toslink and AT&T ST glass.
Do you have any recommendation here for a good ST glass output?

Regards,
Tibi
