Uhuru: Incoming Schematic from the late 20th Century, Captain.
Spock: It appears to be an preamp of a type previously unencountered.
Kirk: Explain, Mr. Spock.
Spock: It is an English Silicon Fuzz Face circa 1980 Captain, but it appears not to ...... distort.
McCoy: For pity's sake Spock, who would do such a thing?
Spock: Graham Bishop in his book "Electronics Projects 3 : Audio Circuits and Projects". 76db
gain, 3.9k input inpedance, 4.7k output inpedance.
Scotty: 76db and 4.7k ? What would that do tay the input grid of a tube amp?
<Jarring Chord> The crew share horrified glances.
(It's just a standard preamp on which the Fuzz Face was based. Probably.)
Actually it distorts with a guitar signal. Oh Well. The Univox Unidrive is similar.
