Whitigir Posted November 19, 2017 Report Share Posted November 19, 2017 I like that terminal blocks, what parts number from digikey ? Is it 600v rated ? Quote Link to comment Share on other sites More sharing options...
Blueman2 Posted November 19, 2017 Report Share Posted November 19, 2017 (edited) Oddly, Whitigir, they are only rated 300V. I got them not sure I would use them, but after visually comparing to the 400V rated ones I also bought, this one simply was better. More clearance from the board and better angle of the wires. Only time will tell if I have any problems, but I sure feel better with these after comparing to the regular 400V black ones from Digikey. And these are far, far away from the trace that a couple folks have had arcing from, so I cannot see that issue coming up for me. Part number 1546074-5-ND With my Carbon up and running, I just spent a half hour listening to Chris Jones' Roadhouses & Automobiles which is a really well mixed and recorded album. I have heard this album probably 100 times, but I was truly shocked by some of the sounds I was hearing. I kept looking around to see where the sound was coming from, but it was the recording. There were several times I was startled hearing things I just did not hear in the same way in the past. Definitely more sound stage, no question there. But also more punch and startling clarity of everything. I am running at 17ma right now, but will retune for 20ma tomorrow and listen some more. That is, if I can get to sleep. I want to stay up all night listening to music!!!!! Edited November 19, 2017 by Blueman2 1 Quote Link to comment Share on other sites More sharing options...
congo5 Posted November 19, 2017 Report Share Posted November 19, 2017 The problem with mounting the 10m90s for CCS 580v bias is that there is a lot of voltage on that metal tab I have not measured it but it has to be well over 600v the heatsink is 6/32 mount hole most times the transistor hole is too small for any PPS washer I have to fit they will crack if you force it and the PPS washers require a M3 or 4/40, so no 6/32 screw good news is there is not a lot of heat here as its putting out ~1.5ma so I have used a nylon 6/32 with 2mm oxide pad and thermal grease Peek would be better have also reamed out transistor hole before mounting to fit washers and 4/40 SS screw with nut through heat sink hole this is all covered in one of the older threads but they are large 600v when let loose is exciting and yes I have had flaming boards this is what I get away with YMMV 1 Quote Link to comment Share on other sites More sharing options...
Blueman2 Posted November 19, 2017 Report Share Posted November 19, 2017 (edited) Thanks congo5. I am going to order some very long Peek screws from the local dealer here. I plan to drill out the hole and put the screw all the way through the back and add a washer. Luckily, Solid Spot LLC, the main importer of high quality Peek screws, is just about 5 miles from me so I can just go pick them up. I changed my Carbon to 20ma (from 17ma) and at low levels, could not really tell much difference. However, when I cranked up the volume, it made a difference. Brighter and more shiny. In a good way, for my ears. I know it is cliche to say you can hear things you did not notice as much before, but in this case it is just true. I keep getting surprised by sounds I had not heard before coming from my old standby albums. I am dedicating all day tomorrow to just listening to the Carbon. I have no real desire to finish the chassis now; I just want to listen to it. Edited December 1, 2017 by Blueman2 Quote Link to comment Share on other sites More sharing options...
bui501 Posted November 19, 2017 Report Share Posted November 19, 2017 ... I can't wipe this smile off my face. [emoji4]Many congratulations, Blueman2. I’ve learned so much from your posts and from the replies from the other members. I built a KGSSHV with lots of advice from members on another thread in this forum, and I’m about to put iron to boards today on my Carbon build. Hopefully, your good vibes will rub off on my build. ) -Vinh Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Whitigir Posted November 19, 2017 Report Share Posted November 19, 2017 (edited) Congratulations @Blueman2 , yes the Carbon is awesome. The reason I asked about voltage rating on the blocks were because I suspect this rating is more about it body insulation in between the terminals spacing, and arcing is not pretty. But it does look very nice and just fine. I still don’t know how they put the rating on these blocks Edited November 19, 2017 by Whitigir Quote Link to comment Share on other sites More sharing options...

I had forgotten about it but this is basically what I did with my GRHV except I used a long M3 metal screw with the shoulder washer.

Blueman2 Posted November 19, 2017 Report Share Posted November 19, 2017 Of course, now I need to build a larger case for all these damn amplifiers. SRX-Plus, KGSSHV Carbon, BH BJT. Oh, and I definitely need a Stax Omega now as well. And a better DAC. Damn you all. If you give a moose a muffin....... Quote Link to comment Share on other sites More sharing options...

Blueman2 Posted November 20, 2017 Report Share Posted November 20, 2017 (edited) Well, the SRX-Plus is still getting love. My wife still likes its sound better than the Carbon. She says the Carbon is too harsh for her, and the SRX is quite petite compared to the humongous Carbon. I used every square inch of the SRX case, but the Carbon is only about 1/2 full. There are albums I like better on the SRX than on the Carbon. For example, my old favorite 'The Yes Album' just sounds better on the SRX than on the Carbon. Can't really explain why. Although my SR-507s are starting to get very worried that I am going to ditch her for an 009 Omega.

JimL Posted November 20, 2017 Report Share Posted November 20, 2017 If you're concerned about harshness, the 007 may work better for you than the 009. Not that the 009 is harsh, but it's a bit bright to my ears, and that can sometimes be confused with harshness. Quote Link to comment Share on other sites More sharing options...
Blueman2 Posted November 21, 2017 Report Share Posted November 21, 2017 After more timing listening to both the SRX and the Carbon on my SR-507s, I am finding both amps reveal 'flaws' ins some of my favorite albums. Beck's Morning Phase is a good example. Parts of that album are way over modulated and distorted. Waking Light, at about 3:35 into the song, is a good example. That is the way Beck wanted it, so calling it a flaw might be the wrong word. But until I had these amps, I did not realize just how overmodulated it was. I will say that the SRX seems to handle the distortion better, giving a more pleasing representation. The Carbon just lays the recording issues bare and is not as pleasing to me. More accurate to what Beck wanted, but certainly not as pleasing. I have both amps on my work desk and each gets about equal use. Just depends on the mood I am in and what the source material is. Not sure where the hell I am going to fit the BH-BJT. New desk, I guess. Quote Link to comment Share on other sites More sharing options...
