Crack / Speedball: LEDs on first board not lighting; voltage tests are within spec

« Last post by agitprop on Yesterday at 02:15:26 PM »

Built Crack yesterday.  Tested and worked well.

Just installed first half of Speedball.  None of the four LEDs on the Speedball's small board light up; the two original LEDs on the Crack's 9-pin socket work fine.  I'd be shocked if I overheated the four small-board LEDs when soldering; they got a lot less heat than the 9-in socket LEDs. I am using a Hako digital iron at 650 and Cardas Quad Eutectic, and I have a good bit of soldering experience.

Got the following, ostensibly nominal test voltages:

Terminal     Voltages (DC)
OA                      80.8V
IA                     176.2V
B-A/B                      0V
IB                     176.5V
OB                      80.5V

I would love to include photos, but I can't figure out how to either directly include images or share imgur links in a post.  Please feel free to clue me in!

Kaiju Stereo 300B amp / Kaiju - IEC Socket Replacement

« Last post by hpleung on Yesterday at 02:09:35 PM »

Hi,

I pulled on my power cord, and the IEC socket came out of the chassis. I think I need to replace it.

What is the specification of the IEC socket used by the Kaiju?

Thanks.

Mainline / Almost there - KREG Voltage issues.

« Last post by Art Andrews on Yesterday at 12:18:46 PM »

I believe I have passed every check test until the very last one. According to the manual, the KREG Regulator Board voltage should be 8-12V mine are 3.6 and 4.11.

I also have only 4 of the LEDs working (and they are so dim you can only see them with the lights out). Interestingly, because the boards are flipped, it is the LEDs on the same side of each, which I feel should be telling me something.

I have gone back over the solders and the wiring. Maybe I am repeatedly missing something, but I can't tell what is wrong or where to go from here.

General Discussion / Re: Tinnitus

« Last post by dth31 on Yesterday at 06:15:34 AM »

You have my sincere sympathy. I also wrestle with tinnitus.

There seems to be a consensus that most ENT doctors and audiologists do not do a good job helping people with their tinnitus. You really need to find an audiologist who specializes in tinnitus treatments. Tinnitus usually can’t be cured but there are treatments that can help many people. Here are some of the useful resources I’ve found.

The health care provider link on the American Tinnitus Association website is particularly useful for finding providers with an interest in treating people with tinnitus:

Hope this helps.

Eros Phono / Re: 6DJ8 vs. 6922?

« Last post by Brooklynbottle on Yesterday at 04:01:36 AM »

I just picked up an Amperex Bugle Boy 6DJ8 that didn't break the bank to try out.
I also just installed the Sowter SUT's so I'll get a sense of how the MC/SUT situation sounds and then add the Amperex to the mix.
I've also got the cord kit ready to assemble.
So many options for improving an already great product.
Thanks for sharing your experience.

Crack / Re: Low noise + wrong voltages

« Last post by vermeil on Yesterday at 01:15:32 AM »

Is there anything more I could try? I do not know what else I could do and would appreciate any input.

I switched over to a premium 6DJ8 and was very surprised at how much better it was.  I believe the manufacturer was Telefunken. 

The presentation was much clearer.  It provided a much better soundstage, better delineation of instruments, it is more musical and really fun to listen to.  It raised my system to a new level.  I would say if you do one thing on your Eros buy a top notch 6DJ8.

Good luck and happy listening.

That's horrible.  I've suffered from moderate tinnitus most of my life, but what you describe sounds unimaginable even to me.  I am so sorry.  I know from personal experience how devastating it is to go to an ENT and have him or her offer only what I call the "physician's shrug."

You've probably already done this but, if not, seek out the various tinnitus user forums on the web.  You'll find not just sympathy but empathy, a community that won't make you feel so alone.

Sublime Subwoofer Amplifier kit / Re: Shielded twisted pair cable

« Last post by Doc B. on May 18, 2024, 12:24:40 PM »

It's not CAT5, it's a single pair - solid core STP cable. Contact Eileen at [email protected] on Monday and she can fix you up with more.

You probably could just use any CAT5 ethernet cable, if you have some laying around...
