A few weeks ago I had an issue with the Acom 1011. After warm up period of 1 – 2 minutes (manual indicates it’s operational after 30 seconds) the red F and yellow IP LEDs started blinking, green OPER LED went off and the amp went into protection for a couple of seconds. I checked everything (bandswitch, antenne switch etc.) and tried again: the amp worked OK. I didn’t take notice and suspected it would be a “hick-up”. I didn’t use the amp for almost a week, so maybe the tubes needed some extra warming up, I don’t know.
Last couple of weeks this problem occured again and more frequent. I had the impression that after a longer warm up period, it worked OK but since yesterday, it doesn’t work any more. Sometimes it doesn’t go into protection but then the output power equals the input power (30 Watts) and in that case, the TX LED on the amp is ON but I don’t hear the amp’s relay clicking. I’ve raised the issue with Acom and as their after sales service has a very good reputation, hopefully we can work this out. I will keep you informed.
