Do I understand right that high power is the key. In other words, you can run low power through the amp with the amp in bypass? The first thing I look for when this happens is something arcing under high power. Check your connectors. Once you arc a connector it will often have a carbon trace on it that will make it keep arcing even without the stress of trying to run to a high SWR load through a tuner.
