I am planning to go for stereo L15d. I have 4 ohms speakers. Also have a pass b1 bueffer. I need to get a linear psu 50-0-50 volts DC right? Is there a recommended one. Would like to build one myself, not a module. Are 63 volt caps enough or do I need to go for more. What kind of trafo is a good option, ei, torroid or r core. I need speaker protection curcuitry. Do I need a soft start module also, any recommended ones? I will probably get these from fleabay. Most of these run on 12v right, will check anyway before getting the trafo etc.

There are two sellers of these boards on ebay, along and zoe_tsang. Could some one tell me about the quality of parts these guys use or which one is better. If I wish to upgrade some parts, which ones will give maximum returns.

kits are the same. I bought from both : packaging in favour of along, but for a kit you don't really care. For fully built boards, you would.

I am looking to build a linear power supply for the l15ds for 4 ohm speakers. What have people used in their builds. Any suggestions on the soft start module.
