you just go to the bottom of the Thiersch product page: www.thiersch-mic.de/en/estm_produkte.html"All products may be ordered by email or contact form. Price apiece + 19% VAT for EU customers! All prices + postage." the email and the form are hotlinked there. And be forewarned, they use a DHL expedited service. It's like 60$ for shipping. They don't tell you this until your order is complete and ready to ship. check I think they will send registered usps if you request it ? |

so i emailed them a couple more times and still didnt get a reply.... turned out they were being sent to my spam folder. they must be so annoyed with me right now. such an IDIOT!!! anyways. does anyone have the Alctron GT-2B body with blueline? if so what capsule version/holder did you use. chunger said his blueline didnt fit in his. thanks I would be interested in the answer to this. tonycamphd |

mine fit no problem, but i had a couple M7 capsule holders laying around, and i'm not sure which brand holder it was? i'm sure the relief slots in the bottom of the headbasket can be dremeled/filed slightly larger to allow any capsule holder to pass through. If anyone has a problem post a pic, and if not me, someone here will come up with a solution for you 8)

i finished the mic. i tested it and it sounded so freakn awesome i couldnt believe it. then i let it burn in for a couple days and now there is an incredibly loud white noise. unusable loud. it already has the aluminum resistor and im using rca tubes. those were the only two answers i could find and those obviously arent the problem. ive spent so much time and money on this thing. over night it went from being my crowning achievement, and the best investment ive ever made to my biggest failure and regret. im at the point i dont even want it anymore. im so tired of working on this thing.

Hi porkyman,
It could be the tubes, you could watch out for a connection problem at the pins. Also, it could be a problem in the Hi-Z portion of the circuit, maybe some residue?
Since it comes suddenly after a week, it could also be a cold solder joint on the pcb or a connection, that broke after the mic settled with it's temperature rising when running and cooling when turned off.
That just as a quick brain storming for troubleshooting.
Remember what it sounded like, when you fell in love with it, this is, what could be achieved with your mic, and debugging it can bring this back. If you are annoyed by the emotional rollercoaster now, delay troubleshooting for a week or two and go for the repair later....

As Smallbutfine mentioned, if there is any flux left on the high impedance sections of the mic, it'll be noisy. There might have been a little dry flux that melted with the tube heat and gotten on the socket pins or something. I'd pull the tubes, check the pins for corrosion. A lot of NOS tubes have some corrosion on the pins, and i think this causes a lot of noise for people. Take some scotch-brite pads or very fine sandpaper and polish the pins on both tubes. Now get some acetone and a cheap pig-bristle brush and scrub the sockets all over, including the PCB and solder joints. Use a lot of acetone and clean until you see no residue left on the pins and/or PCB. Clean the pins of the tubes with acetone and allow everything to dry for a couple minutes. Acetone will completely dry with no residue unlike alcohol. Reinstall the tubes and try the mic. Another test would be to see if the noise changes with polar pattern (if you did the multiple pattern). Also, please check all voltages once again while the mic is powered up and making noise. One more thing, you might simply have a bad tube. Sometimes tubes just go bad. We forget this sometimes in these days of very good QC and product reliability. Back in the days of tubes it wasn't uncommon to buy a box of tubes and find a few that go bad soon after being put into service. you might buy a couple of the cheap WE408A tubes and try them and see if the noise changes or goes away. If it does go away then you know you have bad tubes. I've had good luck with my WE408A tubes, I bought them unmatched and untested and they are noiseless and sound fine to me. They were also like 5$ each. One difference was that I polished the pins and cleaned my boards cleaner than I clean my dinnerware! |

Dude! i've so seen this movie!             ^ all great advice imo, Most importantly, what small said is true, that sound you heard originally is still in the mic, and the problem is solvable no doubt. First thing to my peanut is... Tubes, they are totally hit and miss, i bought a 10 piece lot of northern electrics, 4 of the 6 i've tried so far are in the trash. Second is residue on the hi z section of the mic like small and svart mentioned. Third is a questionable solder joint, i'd take a hot iron and just reflow all the solder points, you can also use a flux pen prior to doing this, just make sure to clean everything up as you go. Please post some hi rez pictures like svart said, of both PSU and mic. also, if you can't resolve it this way, pm me and i'll give you my phone #, then you can get your multi meter ready, and i'll go through my mic, while you go through your mic point by point, there is an answer in there somewhere bud, no worries 8) |

so. i touched everything up. cleaned with alcohol. put some Western Electrics in there and im pretty sure its worse. will let these burn in a little and pick up some acetone and try again tomorrow.

OK, take your time and go thru it step by step.
I am sure we can sort this out and help.

Especially for the Hi-Z portion of the circuit:
Take a magnifying glass to watch out for the slightest shade of residue on the pcb, on the parts themselves and all contacts. Even barely visible fingerprints and residue/stain can cause serious trouble.

it is so much quieter on that clip. you have to take my word for it, it is really, really loud.

OMG!!!! problem solved. it was my ross martin ADC!!!
Thanks again guys for the support.

Uhm, what?
o.O
I mean, what was the prob with the ADC?
Nice you could sort it out anyway!

Glad you figured it out. I see a carbon composition resistor used in your mic.. Was that for a specific purpose? Carbon comps have the highest self noise of any resistor type..
Was your RM ADC set for the wrong sample rate/bit depth output? Sometimes the receivers will lock on but you'll get noise from the bits being dropped.

The resistor came with the chunger kit. Idk why he chose it. Idk what was wrong with the RM. It was just making noise. I may have never suspected it if i hadn't post that clip. It was so much quieter than in my daw i thought i was just being picky so i plugged in an sm7b to hear the noise difference and of course it was identical. I hit the reset button on the RM and boom. Instant silence. I would have suspected anything other than the mic had it not been the mk47. But i read how others have noise problems. i hear noise. So of course i have noise problems too. It really is true what they say. Assumption is the mother of all f@#k ups. Glad you figured it out. I see a carbon composition resistor used in your mic.. Was that for a specific purpose?

what was originally wrong with the mic? was it the RM the whole time?

what was originally wrong with the mic? was it the RM the whole time? yeah. it was just making noise. thats why the mic worked one day and the next it didnt. it was never the mic. i think the Westerns did add to the noise though. i went back to the rca's. ive built a bunch of stuff over the years and am usually underwhelmed. mostly because i build them up so much in my head they can never live up... this thing on the other hand really blew me away. i cant even believe it when i hear my voice coming out the other end. i dont wanna go crazy but its like a dream. i normally cant stand the sound of my own voice but this thing almost makes it tolerable. thanks again guys, and thanks to category5 who helped me through the psu build over on gdiy. |
