I have a Sugden SDT-1 player and an AU51 transport sat in my cupboard, both not working. Both used to work and were in my system. I had been waiting to send them to Sugden but they haven't been accepting service work for many months now.

The CDT-1 works as far as the digital output but all you get out of the analogue is a constant hum. I have tried the obvious things - replacing the DAC, filter and a big resistor on the bottom of the analogue PCB that had rotted away.

The AU51 Transport won't read. Again - I've tried swapping the laser, the whole mech and the mech with the board it's on but no difference.

Both of these are now beyond my random swapping bits approach and need someone clever to look at them.

Ideally, I'd like someone within reach of Oxfordshire if anyone can recommend someone?

I'd like to keep the transport as I have the matching DAC but the CD player will probably get sold so needs to be economically viable.

Thanks
Geoff
