Re: Primo EM200 + simple P48

the EM415N also has better HF extension, by the looks of it, and a couple pronounced high mid peaks

Do we know that the EM200 and EM204 are equivalent when a 470 ohm resistor is used on the EM200? The Jfets could be from different Ids grades, leading the EM200 to have a high or low bias current.
This thread on Group DIY? shows how an EM204 could be turned into an EM200 :?
Not normally a sensible mod. of course, but apparently there were some cheap EM204s going at the time?
if you look at the 2 data sheets they are very similar, and I think it's reasonable to assume they have the same manufacturing 'root'?.....?
Sadly of course both are now obselete, and have been replaced with the EM415N ..?
Similar to the EM200/204 but with a steeper LF roll off, by the look of the data sheet graph.
