1166KT - Super RIAA Stereo Preamplifier Kit

Ability Level 3: IntermediateProduct Format : Self-Assembly Electronic Kit ( Soldering Required)
Ability Level 3 : Intermediate

With the spread of CD players, many amplifiers and mini sound systems no longer have a phono input for a record deck. As a result, your expensive record collection has become unusable.

This problem can be solved by using this hi-fi quality stereo RIAA preamp. The circuit uses an LM833 IC that is well specified for the application and ensures low noise, very high sound quality and reliability.

The board requires a 15Vac centre tapped transformer (not supplied) and incorporates a bridge rectifier and smoothing capacitors.

Kit includes all board mounted components including a pair of high quality phono sockets along with solder for assembly.
