Amp Supply LK500ZC 1 KW 160M-10M $800: The amp is an early model and does not have the WARC bands. It will load up on 17 m with 700 watts out with no difficulty when the band switch is on 14 M. The ALO board has failed and has been bypassed. Despite this, the amp operates as expected. A new rectifier board (new caps, diodes, resistors) has been installed. High voltage is 3000+ VDC. The amp is in excellent physical condition – no dents, minor hairline scratches. The photo shows 1 KW output on 14m. More photos on request. Shipping options: free pick up in Boulder CO or I will drive up to 3 hours from Boulder CO to deliver the rig for $75 or buyer makes his own shipping arrangements at his expense. Because of the amps’s weight and possible damage during shipping, I will not box up the amp and ship it but will deliver it to a local shipper. $800 Cash or USPS money order only.; Listing #1757872 - Submitted on 02/04/26 by Callsign N3AJB - IP: c-73-243-93-108.hsd1.co.comcast.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

Need help with THP -1.5 KFX not keying: My THP AMP stopped keying with my IC7800. The amp tracks band changes, fan working, no fault LED’s on, cables connected not loose. Could the issue be an internal fuse, bad transistor on relay/PA board. Problem started suddenly.
Does anyone know a ham who works on these THP amps? I live near Philadelphia.
Any advice would bee greatly appreciated. Thanks
Bob
