Somewhere in this forum there is a link to my thread at Harmony Central, where I did a build thread.
In my opinion, the 18 watter is pretty straight forward, much "easier" than I expected. The drawings showing parts layout and wiring are excellent. I basically did one wire at a time, checking off the completed wires untill each one was run. I triple checked as I went along that nothing was out of place and mine fired up on the first try and worked great. I did not expect it to be so quiet even at full volume.
I think anyone who has soldering skills, can properly identify components (in the instructions you get the capacitor and resister codes) and run wires from point A to B can build this amp.
To top it off, Stephen has been so very helpfull, always ansering my questions immediately by email and IMO has gone beyond what he needs to have a successfull company. I really think he cares that his customers get a working amp done!
Doesnt hurt they are in Canada either, and I dont have to order the kit from the USA.
