FS/FT OM Power 4000a Auto tune amp: Excellent condition, New Tubes 10 months ago. Autotune 10-160m 15 to 20 watts input nets legal limit. Will easily achieve 4k watts with low grid current. Prefer you come see and use the amplifier.
I have had the amplifier for 4 years. Decided I like solid state better. If you have a solid state amplifier, I would consider a trade or partial trade. $4800; Listing #1741190 - Submitted on 08/28/25 by Callsign WG3U, Modified on 08/29/25 - IP: publicsafety.docogonet.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
