I have had the amplifier for 4 years. Decided I like solid state better.

Ten tec titan 425: I have owned this amp for about 3 years and it's never gave a minutes trouble . It comes with the original power supply . It's wired for 220vac . The tubes are not new and neither is the amp . But it's a good running dependable amplifier . In the picture the amp is showing right at 1800 watts carrier as you can see the grid current is well within spec .a bad tube will draw more grid current to get the power out . This was with 70 watts drive . $1400.00 and you can pick it up at the shelby hamfest; Listing #1740596 - Submitted on 08/22/25 by Callsign KG4WPW, Modified on 08/27/25 - IP: 155.sub-174-218-51.myvzw.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
