Gareth, Don't know about the 750 but Kenwood replaced all five PA in my TKR-850 trunk system, paid the labor and everything. All I paid was a penny each for the parts. Paul

I recall that Kenwood was scrambling around changing these under warranty when the 750 was first released. I have just removed one from service that was only pushing 15 Watts @ 7 Amps (Set for High power). This particular repeater has already suffered dry joints around the PA stage which was not the cause of fault this time. Can any Kenwood dealers shed some light on this common problem and suggest the replacement P/A part number for around 150-160 MHz? Interestingly we replaced the -750 with a Vertex VXR-9000 repeater and commissioning tests revealed about 3 dB better sensitivity than the 750's for 12dB Sinad.
