I need some touch for my old Toshiba SD-2960 DVD Player. So here is the TentLabs XO2 @ 27 MHz, a perfect yet affordable reclock solution for my wallet.

This is actually a simple PCB. Not all parts used, since this PCB actually “upgradeable”. I bought the XO2 version (Clock Upgrade + Low Noise PSU). If in the future, I wish to upgrade to XO3 (XO2 + S/PDIF reclock), I just contact Guido Tent @ TentLabs to put more components on this PCB.

From my previous Aikido project, I’m still thinking of improvement of my B+ PSU. Well, I still hear a small hum. There are several possibilities to be tried, but I’m thinking of improving my B+ PSU first. If it fails, then I will think another way

From the LC-LC filter used before, I’m moving into a more filtering. Well, I’m talking about another stage of LC, creating LC-LC-LC filter. Previously, I used two Samhwa 220uF/500VDC capacitors. It’s a nice price/performance capacitor - I have to admit that. But, I need to change into a higher level (to see how much the improvement).

First I remove two Samhwa capacitors. It was a tiring job to remove those two capacitors (phewww). Then, I change the first capacitor with Korean “Motor Run” Oil Capacitor (60uF/400VAC), second capacitor with Mundorf M-Lytic 560uF/400VDC, then finally with another Korean “Motor Run” Oil Capacitor (40uF/400VAC).

Well, don’t ask me why I use this Korean “Motor Run” Oil Capacitor. It’s simply because I have no budget. If you have enough bucks in your pocket, go with ASC Oil Capacitor then
