I am going to replace the output capacitors in my ASL 2004DT preamp with auricaps. I have never done something like this. So are there any special skills I need to acquire before I embark on this endevour? Any special tools apart from a saudering iron some silver solder? I am thinking its a plain pull out the old cap and put the new one in and solder away. I did some soldering about 15 yrs back but it was simple soldering of wires. So please advice me if there is anything else that I should know about. Also what kind of improvement should I hope to see with this change? Any advice to this novice would be greatly appreciated.
