 RF2k-S Upgraded Linear Amplifier – Mint  
Upgraded RF2k-S linear amplifier that is in "like-new" condition.
.
Professional Build & Upgrade: Began life as a RF-Kit RF2K+ that was never used, it was fully upgraded to RF2K-S by Ed, W2PH, the authorized RF amp service center in Melbourne, Florida. Since then (for the last year) it has served as backup and has only been used a handful of times.
.
The "S" Treatment: Upgraded with the full RF2k-S controller, tuner and internal components, bringing it to current RF2K-S specs and ability to upgrade firmware going forward.
.
Whisper Quiet: Modified with high-end Noctua fans, making it virtually silent during operation.
.
Performance: Reliable, high-power performance LDMOS Legal Limit++
.
This is a rare opportunity to own a like new unit that retails for over $6,000. Save $$ and skip the wait times for a new build. Price: $4,000 + shipping or pickup South Florida. Photos available. I will be at Stuart FL hamfest Sat 3/21 and can bring it if you want to pick it up there.
