NVA Amplifier Repairs
NVA AP80 Amplifier
I got this with a burnt smell, looking inside showed the RHS channel had gone into melt down (as they do). The board was too damaged to repair and they are not available from NVA as a spare part so it was scrapped.

This was a very early model from NVA (Nene Valley Audio), one that you can get into the case, later ones were sealed. A resistor had burnt up near the power transistor, luckily no other damage had occurred apart from dry joints on the large diameter cabling used in the internal wiring.
