Having searched through this forum I have been unable to find a list of part numbers for modding the SB3. Perhaps someone could point me to the relevant thread, or post any part numbers used to upgrade components here.
For starters, the Power-One PSU seems to be an obvious choice, ie HB5-3/OVP-A http://uk.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=5059537&N=401 or http://www.cascadesurplus.com/catalog/product_info.php/cPath/99/products_id/856 Interesting how it costs $3.50 in the US and £23.75 in the UK! But what of other components? The review of the Bolder mod at http://tinyurl.com/ro2h2 refers to the following: Digital: - Replace two main power supply capacitors with higher value, low ESR versions - Replace the digital buffer capacitor with higher value, low ESR versions - Remove the 12.28MHz crystal oscillator (optional) - Remove the headphone opamp circuit (optional) - Reroute the digital signal path to the S/PDIF - Replace the stock S/PDIF with a 75 ohm WBT NextGen, gold plated copper RCA Analogue: - The internal power supply caps are replaced with high quality Panasonic capacitors with a low ESR. - The cheap RCA analog output jacks are replaced with Cardas Rhodium plated RCA jacks. - The internal output gain stage is bypassed and coupled directly from the output if the DAC to the Cardas RCA jack with a standard SoniCap. This lowers the output voltage to just over 1 volt but should not be an issue as many preamps have ample gain to compensate. The unit under review has a pair of SoniCap Gen 2 bypass caps paralleled to the standard SoniCap. - The existing DAC's power is derived from the internal switching power supply rail. The modified DAC's power is rerouted to draw from the linear power supply rail. - The headphone opamp is removed (optional) - The internal 12.28 mHz clock crystal is removed (optional) - The stock Burr-Brown PCM1748 DAC is removed and replaced with the higher spec'ed Burr Brown KE series. I'm more concered about the digital mods, so would like to know where to obtain the following, and their spec: higher value, low ESR power supply capacitors, higher value, low ESR digital buffer capacitors, 75 ohm S/PDIF WBT NextGen, gold plated copper RCA (OK I can track that one down). -- mortod ------------------------------------------------------------------------ mortod's Profile: http://forums.slimdevices.com/member.php?userid=4651 View this thread: http://forums.slimdevices.com/showthread.php?t=22300 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
