Hello All!
After much contemplation, I decided to give Steve's SE84C based kit a whirl. I have build a few internet kits from custom designers in the past. I always wanted a Zen amp and just recently became re energised in this hobby but wanted to avoid the long wait for a Decware build.
This is what I found about this kit building process todate using the stock parts listed:
1) Parts are readily available
2) Part costs are about $340
3) Shipping of parts comes close to $60 from 4 suppliers
4) The costs can easily double depending on personal custom options
5) Edcor at present has a 3 week lead time
6) Mouser is about a 2 day LT
7) Decware ships priority mail with about 2 day LT
8) Parts Express is about a 2 day LT
9) Care must be taken when ordering - a wrong part ordered will skew the above
10) Building the kit is straightforward and not complicated with the proper skill(hence Steve's many pages on soldering!)
I received most of the parts for the amp and presently waiting for the trannies. The board is well built. The components are installed and waiting for an ordered solder station to flow silver solder.
This video is an interesting piece of film cap polarity, Yea that's right, film caps do have a polarity that
should be followed in quality amp builds. Something new for me too

In the video Carlson uses an oscilloscope and builds a black box circuit to check film caps outer wrap to determine the best shielding circuit insertion. A good informative video. I just used my ears and the mag phono input on the Heathkit
