Second, I will show a circuit implementing the JFET in a simple class A gain stage with a voltage follower. Last, we will use the gain stage in three applications: an instrument preamplifier, a microphone preamplifier, and a line mixer. The JFET amp shown here can be applied to a ...
diy preamp For this year’s Hackaday Prize, [skrodahl] is building a beautiful tube preamp.It’s a masterpiece of glass and free electrons, it already works, and it sounds great. This circuit is a modified version ofthe Bastard, an amp published in the Danish magazine Ny Elektronik nea...
I've tested this small circuit with the external microphone input on a dictaphone and to my astonishment, it actually works rather well even without the bootstrap. Interesting little experiment if you have a few minutes. Judging by the output level, I expect it won't need a x1000 (60 dB...

Built the preamp with the power supply. Works first time no problems. Sounds great on standard settings but will adjust input impedance and gain for fun. The service from Skrodahl was excellent and very generous. I highly recommend buying from him. It was great fun building the kit and ver...
Revisions A and B. Also called "stripe" are the basis for all the other revisions. The signal and line amp are based on the 1108 microphone preamp and use a FET as the first active component in each amp stage. The sound is characterized by a small amount of distortion due to the lack...
