Audio Note Oto

This amplifier came to me because one channel of the phono stage wasn’t working. On examination I found two faults. Firstly, a resistor was touching one of the earthed cans of one channel of the phono stage, doubtless caused by ‘valve rolling’ at some stage. Secondly, in common with a lot of Audio Note equipment the cheap modular phono sockets have a plate which identifies each input screwed to the sockets. This plate can prevent certain phono plugs from making a good connection. One way to improve things here is to remove the plate.
