I am not sure, since the frequency response is not the same on the low end.jalmonsalmon wrote:So ...
MP38A's work for this and sound more or less the same as the CV7351's?
Like blind fold comparison test?
Theres is a diffrence from about 10db @ 10 Hz, that means there is three times less low frequency level using the MP38A below 30Hz,
but I think it is finally not audible.
Next, will omitted more specifically change the capacitor between base and collector, to see the influence on the frequency response.
The next task is the measurement of each FET-stage seperatly.
To the end with, I will build the device, but that is a winter work.
