Hi all, this Penta 1 Amp board has suffered heat damage, I haven’t found the cause yet all components are with in spec, the result is that the 10k 2watt resistor has taken a hammering. I’m thinking that a simple dry joint could have started the mess, as from the images, you can see the condition of the board, I’m now concerned the insulation properties have been well destroyed, but not sure best way forward, I can Can IR test ( but from where and at what voltage not to damage anything) thanks team regards Brad
