Title: High test point voltages Post by Gilf on 03/03/24 at 17:01:13 I completed another zkit1 build today. Doing the test point voltages I’m getting 438v right at test point A? Faulty capacitor? |
Title: Re: High test point voltages Post by Gilf on 03/03/24 at 19:52:38 It was a false alarm. I realized I did not have a volume control installed on this unit so I think (?) my voltages would be slightly higher since it’s running wide open. There’s a double happy ending here. In reviewing the schematic over and over, double checking everything, I realized I was plagued by the 2019 schematic again instead of using the 2021 version. I had incorrectly wired the output transformer to pins 6 and 8 instead 7 and 9. Fired it up and …. Beautiful! What will I build next? :D |
Title: Re: High test point voltages Post by Sean on 03/04/24 at 03:22:01 Love it, one of a kind. I noticed the Belden speaker wires, is that your go to wire? I use it in my system and like it, I use one set black and orange each for both pos and neg. |
Title: Re: High test point voltages Post by Gilf on 03/04/24 at 11:32:41 Thanks, Sean. These kids are crazy about “melting metal” (soldering). I can see them graduating to a welder in a couple years. That Belden wire is just my go-to for “throw it together and see if it works”. I did use it for about 20 years- good speaker wire. My wife has a UFO in her office system and I still use a triple braid of it with that. I found a profound improvement going from one strand to three when paired with that 2 watt amp. I use Decware ZStyx in my main system. I honestly haven’t done a lot of A/B with the zstyx. Once I got them I was happy with them. Interesting idea you share about using one black/orange for each +/- leg. I’ll have to make up a set and try it out. |
