[Amps] Re challenger 2 amp

[John Randall]

I am pleased to say that I found the fault after dropping the front panel and using a mirror to see behind the 160m coil. I found that the turns had dropped around the back and were not next to each other. There was also no adhesive on the turns either. A simple fix was to place a 10mm cable tie over the top of the former and one at the bottom and gently tightening the cable ties, I slid the bottom one upwards until the tuns were tight against each other all round. Testing the amp with 10w drive produced ample rf out. 
Lesson learned is that even "experts"  make mistakes.
