Rare 1108 mic preamp module, very early serial #29 - made 1966 one of the first. Used to be racked in a rack that held 3 of these modules, which was then sold with 2 in it, with this 3rd one taken out for later racking, which we never got around to and probably wont.

These switches are a combination of a depletion type Field-Effect Transistor (FET) and a band-switching diode in an SOT143B (BF1108) or SOT143R (BF1108R) package. The low loss and high isolation capabilities of these devices provide excellent RF switching functions.

The 1108 is a fixed-gain (40dB) FET amplifier module that can be used in a variety of applications. It’s simple, class-A design lend it well to experimentation. To build a mic preamp, one only needs to add gain control, phantom power, and their choice of transformers. The module runs on +24vdc. Price:

BF1108 - plastic surf ace-mounted package; 4 leads SO T143B.

2012年2月10日 · The 2108 was a great box in just about every way, however, the FET in the old 1108 is unobtanium for modern manufacturing and the coupling in the 2108 was totally different and both of these things add up to a very different sounding box.
