It took a few hours to draw the layout from the schematic, then a few more hours to optimize and modify it. This is the sixth amp that I've done, (also have done the RA-1, Buffered Cmoy, Meta42, Pimeta, and PPA on sockets as shown on my web page) so it gets easier to do this with less errors in the process.
Soldering on the socket pins is less work than wiring on a proto board since the pins are firmly and evenly held in place and the solid 24 awg cat5 wire holds the sockets together. I keep the wire and solder above the shoulder of the pins so there is plenty of space between the soldered pins. Any wires that cross other pins or wires have the teflon insulation slid down the wire as I go on to solder it to the next pin. No problem with shorts. I use a wire list to make sure I get all the wires done on the right pins. It took me three hours to solder all the two and three pin wires (28 of them) and another three hours to do the last seven wires (four pin wires (2), seven pin wires (2), and ten pin wires (3)). Wire list is on my web page. It looks pretty crowded only after putting on the last few wires.
Anyways, this amp sounds really good with all my Grado headphones and I haven't gone back to any of my other amps for comparison yet. A balanced module can also be added to this later.
