I've got a couple of MTE SF-23 torches that I got through DX a couple of years back that seem to have developed a problem.
When I switch it on its fine for a bit then drops to half power regardless of what setting I have it on. I've tried mixing batteries and the parts but nothing seems to have made a difference.
Sometimes it comes back to full power after I cycle through the modes, some times it doesn't, sometimes it comes back by its self, sometimes it doesn't.
Anyone had similar or know what might be causing it?
When they work properly they are really good so I'm not to keen to replace them.
