"The company may be gone, but the amps must Rock On!"

Brand new replacement Filter Cap Kit for your SWR SM-400 amp!  This kit is based around the 4700uF cap, as used by SWR in the original version. If you prefer to up your caps to 6800uF (as recommended by SWR in later schematics) see my other listing for the 6800uF version.  Kit includes: four Nichicon 4700uF/63v radial caps, two Nichicon 100uF/35v radial caps, and two 100uF/250v radial caps, all are High-Temp 105c for long life. All caps are new and genuine Nichicon and have been sized to be a perfect fit for your amp. The original caps for these amps may be thirty+ years old! Replace them now and keep your amp running its best!

Authenticity - These caps are current production and the highest quality Nichicon. The original caps in SWR equipment were sourced from multiple manufacturers. I've put this kit together using only one manufacturer for uniformity, ease and reliability. I guarantee they will outperform the originals!  All caps have been tested on my B&K 878 LCR tester and are within spec.

About us - We are dedicated aficionados of the late Steve William Rabe's work and aim to keep his creations running for decades to come.  Our offerings are currently limited but as the business grows we hope to add more replacement parts, even the custom pieces, to keep your amp running and sounding its best.

About our parts - We make every effort to supply you with the exact same part your amp was originally built with. But technology moves by at a lightning pace and in many cases the part, and sometime the manufacturers themselves (!), no longer exist. In these cases, we offer the best suitable, high-quality replacement we can find, which we have thoroughly tested in our own equipment.

Terms - If not completely satisfied with our offerings please return the item(s) within 30 days for a refund or replacement (your choice).  Returned items must be in listed condition.
