As if by magic the shop keeper appears I knew someone would be along that knows what they are talking about
It's a pity a good friend of mine doesn't listen as he'll soon be facing a huge repair bill His KSA250 is running miles too hot & suffering from thermal runaway. I'd expect thermal stability inside of a few hours, this one just kept getting hotter & just before i left there was no way you could keep your hands on the heatsinks for more than a second.. Must have been 60C+ so the transistors must be getting on for 80C+ or more
It's soon going to go bye bye. I did bring this up but all i got in response was "it's a Krell, it's what they do"... I rest my case
