I am interested in building a ribbon mic. The biggest question I have is the transformer. Does anyone have any info on how many turns in the primary and...
I saw that site but didn't see any specifics on the transformer. Actually most of the sites seem to neglect the info on the transformer. There are a few sites...
... Recently retired Jorgen Wuttke was R&D manager at Schoeps from before I got involved with the Calrec Soundfield Mike. One of the truly great microphone...
i too do not mind electrolytics. i am a little chary of tantalums, especially after one blew up. all did was misconnected, and the voltage was quiet small....
I'm wondering if Shoeps has any sort of patent for the sphere microphone or if anyone can manufacture similar mic's. I have inquired with Shoeps but they did...
Hey Mike, It's Rick from RickshawRecords. There are several Xformers that I recommend in the tutorial, and a few more have been recommended to me by people who...
With the discussions about blown up tantalums, here is what can happen to a car battery. http://www.vinland.com/Car-Battery.html Be extremely careful! Bertho ...
Robert, I don't know if anyone else is having this problem - but your emails are coming out very difficult to read. There is no formatting, and everything runs...
Thank you to all that contributed to the discussions about the Schoeps design. I think it helped define some interesting issues about this amazingly simple,...
A number of posts in early oct06 deal with the design of a ribbon mike transformer. This was based on a large (expensive) S&B TX103 core but is applicable to...
I'm looking for shematics for a XLR adapter similar to the DXA-6 by Beachtek. Googling has resulted in my finding rumors that such a diy schematic exists but...

I have just uploaded a file in the files section, see the Nakamichi CM- 300 circuits, hicksamps.pdf. It seems to be related to the Schoeps' circuitry dicussed...
it is a little odd. the output transistors, i suspect will only be on if there is phantom power. powering the fet with a battery might be quieter than zenered...
Hi, Yes it is odd. It seems stupid to run it from batteries AND phantom power! Roger Gustavsson ... on if there is phantom power. powering the fet with a...
I will sometimes (recently) replace a zener with a battery in a simulator schematic. I'll do this if I know that a real zener would be drawing enough currrent...
Zap, this piece of work you are doing is actually VERY interesting! I thank you for it but I have some more questions :-) Can the pair of 2N5087 be replaced...
Luc, Thanks. I'm going to pass this question to someone who is more qualified than myself. (Richard Lee perhaps?) I think it's a good idea but, those matched...
i guess hfe balance will effect the impedance balance of pins 2 and 3, but i do not know by how much. anyhow, i buy bc 560s in bags of hundred (costs about 5...
