For sale is a rare vintage The Mod Squad Line Drive passive preamplifier (circa late 80's).

This passive preamplifier is in very good condition both functionally and aesthetically. I cleaned all jacks with DeoxIT. Sound quality is fantastic - this preamp is entirely transparent. Build quality is excellent; unit has a 1/4" thick steel faceplate and overall great feel. Finish is in good condition - no marks on faceplate, some pitting on the unit chassis.

Note: there is some audible scratching when using the controls - the selectors and volume potentiometer could use some minor cleaning.

From an excerpt from a Sterophile review from April 1987 (John Atkinson, Anthony H. Cordesman):

The Mod Squad Line Drive System Control Center is a purely passive stereo switching unit with a volume and balance control, five line inputs, and additional facilities for two tape decks. It allows the audiophile to replace a preamp, with its active gain stages—and resulting coloration—with a device that introduces no distortion or coloration other than that in the wiring, switches, and controls.

Tiffany jacks are used selectively for two pairs of inputs and one pair of output jacks. The unit uses Lorlin selector switches. Wonder Wire, Wonder Solder, and Teflon-insulated LC/OFC wiring. Construction is on the battleship side, and the styling and feel are excellent
