Build directions

This design is very easy to build. You can of course solder everything and then apply voltage but maybe it doesn't hurt to be a little cautious. You should start with all low SMD parts except for the buffer and the opamp becuase it's harder to solder the SMD parts when you have big parts in the way. For this solder job I recommend a good pair of tweezers. I use a type especially made for SMD. With this tweezer I get a very good grip. You must also have a soldering iron with a small tip but at least 50 watts in order to be able to solder the buffer which requires lot's of heat.

Start with all low SMD parts except for buffer and opamp.

1. Resistors
   Transistors
   Trim pot (if you use it)
   Capacitors, not the hole mounted ones
   Rectifier bridges, at last
2. Then continue with the high electrolytic caps, mount all caps
3. Connectors
4. Jumpers
5. Transformers
6. Varistor

Good luck and happy listening.
