Old Crown Pre-amp model SL-2

Where can I get help repairing on old Crown pre-amp model SL-2? One channel is not working.

    I'd suggest HARMAN Pro Tech Support. You can find contact info in the sticky thread at the top.

    Generally speaking tech support is unable to help much with vintage products like the SL-2 as Harman no longer keeps parts in stock. Your best bet is to track down a local vintage audio repair shop, who generally specialize in the repair and service of older equipment.

    Troubleshooting should be fairly straight forward. It's multiple stages of opamps with only the front end of the phono preamp having discrete transistors. If a scope is available you should be able to inject a line-level signal into both channels, follow the signal's path from stage to stage while having a working channel as a reference if anything looks strange or distorted in the channel being investigated. Schematics should be available from Crown's website. I've owned the SL-2 for nearly 30 years and it wasn't new or working when I got it. Other Crown equipment in my system include DC-300A, D-150 and D-75 amplifiers. I wouldn't have anything else. What I am in desperate need of is the illuminated POWER switch for my DC-300A. It's a LEVITON brand rocker switch with a red Fresnel lens backlit with a neon bulb.
