The power supply on my TiVo HD died. Was ready to order the capacitors when lo and behold, an eBay listing came up for a new TiVo HD only 15 miles from me. I bought it, brought it home, opened it up and it had a power supply I hadn't seen before. It turned out to be the seldom seen or mentioned AcBel Rev. A 10 capacitor, Model ST7002-BW0G, TiVo part number label SPWR-00011-000 072730464A . Also silkscreened on the board is R03M30-0001l P1-006 and the date 2007.5.11. The capacitors on board are (1) 100UF 25V at C9 , (1) 1000UF 6.3V at C15, (1) 470UF 16V at C20, (1) 1000UF 16V at C31, (2) 47UF 50V at C23 & C29, (3) 2200UF 16V at C14, C17, & C27 and (1) 470UF 200V at C4. The last one is Elite brand, is shorter and stubbier than the CAPXON, and has a black plastic top rather than the scored aluminum.

The HD model came with 2 power supplies. An 3Y one that was similar to the one used in the original S3 OLED (minus the 7.5V feed) and an AcBel one. Both can be used interchangeably on the HD model.

I've seen that, both of those are called Revision B0, and one or both has 12 capacitors. I'm guessing that this one AcBel Revision A, 10 capacitor, must've been used for a short time in the earliest production models
