Reese Sorry slow - I had this same question myself. I went to the page for the equivalent CGS version of the module and used that - PN4250A. I used 3 pins worth of a pin strip to make a socket. The first one turned out ok in the circuit, though.Reese P. Dubin wrote:Regarding the Random Source module in the Edelweis, what is the specified noise transistor type? Mine did not come with the SMT installed, and the BOM does not have it listed that I see.
I think Ralf makes a note of this in the La Bestia II build doc:
Ralf wrote:For the Noise Source you have to select a noise transistor. It is recommended to use a socket for the (through-hole) transistor or simply stick the transistor in (without soldering) so you can test a couple - while the aim of the transistor manufacturers is to have as little noise as possible, we are interested in exactly the opposite for the noise source, so check out level and sound(!) of various types and pieces. Since the temperature of the transistor is also relevant for the noise generation, it is recommended to wait for a couple of minutes so that the transistor can warm up before you evaluate the noise quality.
