Crown Straight Line SL2 preamplifier in very good condition, serviced

Replaced power micro switch. Checked functions.

Tested.

Why are these so desirable?

According to one source on the net:

"The SL-2 and PSL-2 exhibits an excellent build quality, and an excellent combination of features and ease of use. Their relatively small size (1 rack space) and reputation for long term dependability keeps the resale value high.

Their sound is best described as "invisible."

Another factor in the pricing is that they were never made in the large numbers that many of the more mass-market units were, and as a result, "supply and demand" economics come into play here."

Description:

The Crown SL-2 packs exceptional audio performance and a lot of features into just one rack space. Add this to excellent design and construction quality and you'll see why they routinely sell for $500 today - even though they are 35 years old. Crown made these superb preamplifiers in Elkhart, Indiana, USA from 1981~1995.

The SL2 has two tape loops, a fixed external processor loop (EPL), a precision phono preamp with calibrated gain, 1% resistors and 2.5% capacitors, tone controls, a stereo-mono-reverse-mute control, a rumble filter and indicator, and all these can be bypassed one-by-one, giving rise to the STRAIGHT LINE TWO model name. There's also a superb switchable Loudness contour that's the best I've heard, boosting the extreme deep bass and not muddying up the midbass.

The earlier Straight Line One was a very primitive preamplifier that took up two rack spaces and wasn't much more than a selector and volume control.

This STRAIGHT LINE TWO lives up to it's name, with actual measured performance of both the ancient samples I've tested of 0.00005% THD (that's four zeros!) and +0, -0.4dB response from 4 Hz ~ 110 kHz!

The SL-2, seen here, was made from 1981~1985 and the PSL-2 was made from 1987~1995. The PSL-2 is the same, except that the AUX 1 input is labeled "C.D." and AUX 2 is simply called "AUX."

Shipping to states in longitude of Colorado, farther west or rural parts of the Midwest will be a little more, billed separately
