February 24, 201511 yr comment_674165 Yes, I like the Bel Canto designs. This is a Hifi2000 Pesante box of 2U and I used the typical heatsinks of 63.5mm high with 5mm PCB spacers. I only made some low quality photos with my phone I mounted the power LED behind the icon Report
February 24, 201511 yr comment_674167 Excellent! A shame the knobs couldn't be symmetrical around the midpoint Report
February 24, 201511 yr comment_674170 Beautiful. Amazing work...and really like the "remote" power switch and volume control. Nice. Edited February 24, 201511 yr by JoaMat Report
February 24, 201511 yr comment_674185 Wow, that is really nicely done, with great attention to detail! Report
February 24, 201511 yr comment_674187 Well thought out with amazing execution. Beautiful work! Report
February 24, 201511 yr comment_674255 Excellent work, attention to detail, a step further in the DIY world. Congrats! Report
February 25, 201511 yr comment_674332 Yup, a very attractive presentation PICaudio. Good work! Report
February 25, 201511 yr comment_674334 Many thanks, I might not build this amp without what I have learned in this place Report
February 25, 201511 yr comment_674349 How is the toggle switch on the back wired? It only affects input selection? Report
February 25, 201511 yr comment_674350 Great work! And where did you find the plastic shaft couplers? Report
February 25, 201511 yr comment_674353 How is the toggle switch on the back wired? It only affects input selection? I'm guessing he implemented the same thing that Justin does, which is simply a switch between the XLR and RCA inputs. I can't remember the exact wiring off hand but I did the same thing on my KGSS Headamp clone. And ditto on the question regarding the shaft-couplers. Those things (even the metal ones) are like hen's teeth it seems. Finally, that's a simply superb build, PIC. You should be very proud. Report

Finally, that's a simply superb build, PIC. You should be very proud. The metal can be found at Mouser if anyone is looking - keystone part# 1453. Report
February 25, 201511 yr comment_674358 The switch is simply a 4PDT ON-ON unit. Wire the 4 poles from the XLR inputs to one side and the RCA input as plus and minus as ground on the other end. Dead simple. Report
February 25, 201511 yr comment_674362 Don't you need to ground the - inputs to the board when using the RCAs? Report
February 25, 201511 yr comment_674366 You do that at the switch. + - - + XLR x x x x Output from switch + G G + RCA G is tied to common ground Something like this. Flip the switch to RCA and it grounds the - inputs to the amp. Report
February 25, 201511 yr comment_674376 Yes, I have connected the selector according to Birgir's explanation. I made these shaft couplings (Delrin), and I used steel pipes first but I had some problems because the knobs don't turn uniformly and I saw that the pipes were a bit twisted (or crooked, I'm not sure what the right word to describe this problem ) I decided to change these pipes and made another of aluminium/carbon fiber (I have used an arrow ), these pipes are very fragile and they are easy to broke when I tighten the screws of the shaft couplings, for this reason I reinforced the pipes in the ends.
