@Larryi - Lesson Learnt well, unlike Tube preamp which is self biasing , I agree that swapping popped tubes could have damaged my Other Amp.
It could be a blown fuse or a resistor, but damn this unit requires an experienced tech to even open it. unlike other tube amps I have seen, this unit is almost concealed. The Auris company in Serbia gave me " fantastic solution" take it to their service center in California, while I live in Canada. Upon calling the service center he said it would be cheaper for him to fly to Canada, as both units crated weigh almost 100Kgs. Canadian distributor spoke to me and asked me to take it to Edmonton 300 Kms away to their dealer. I am going this morning and will keep you all posted. I once again appreciate all you guys for your input and advise.
How do I post pictures?
