I have recently acquired a rather nice Sansui TU717 tuner.
I have connected it up to an 8-element roof-mounted aerial, but there is hum on selecting narrow bandwidth. The tuner is much quieter on wide bandwidth.
In addition, the output through the right channel is much reduced in comparison. I am able to equalise the output by turning the output level, which is usually used in conjunction with the variable level input, to 5.
I appreciate it is difficult without seeing inside, but does anyone have any ideas on how to resolve these issues? Probably more importantly, can anyone recommend an engineer who would be interested in carrying out any repairs?
I am based in Gloucestershire.
Cheers Roy.
