It was not a standard build. I'm sure you could do a standard build in under 75 hours.

A second time... hmm. Well, there are some things I would do differently, like use a metal case (wood is really nice, though. it's just that panel mount parts are designed for metal, which requires you to make a lot of recesses in the wood.) I would also do seperate cases. But, these two things would save time.

I'd say I'd be able to shave off at least 50 hours, maybe even up to 100. I did tons of research, which was a huge block of time. Now I have a good idea about what parts to buy and a sorta-parts list that wouldn't need much changing.

Thats much better

and i didn't think you were counting research time!

What wasnt standard about your build besides the case?

Other, more minor additions were the switches to mute the the headphone, speaker, and preamp outs, a loop out, multiple headphone jacks, and the leds in the front; all the wiring really added up. Also, the case was custom built by my father and made entirely out of wood; it took him a long time to drill out all the holes and recesses for all the mounted objects. Wood is very difficult to use for the front and back panels of an amplifier since almost every case mounted part is designed for thin metal.

Wiring and research took the longest for me. If you can reduce those two as much as possible, then your build will be easier.

I'll post some pics soon, as I just installed the major pain in the ass Cardas Patented Binding Posts.

1. You need to learn circuit knowledge
2. Buy some cheap components to practice their own hands
3. After doing some products with some teachers to communicate, to help you improve the shortcomings of continuous improvement
