On the underside of the uP enclosure there is a screened wire. The inner goes to pin 15 of the uP where does the sceen go? mine is not connected. Pin 12 would be a good candidate but I woud like to be sure

The original LED is back in place and in 'play mode' with the arm stuck as far as it will go,, I rotate the counter cam and it pulses the optodetectors about 11-0, 11-0 volts as it is turned on both. so I am happy the OPE1 parts work. I now need to work out what makes the arm move then stop short of the record because you won't get any pulses

The IR LED is definitely broken. What is a suitable replacement part please?

The << >> buttons do nothing at the moment. The LED I am describing is part of an assembly which has 2 detectors as well on a little PCB by the motor for the arms, I think you are describing them as 'optos at the end of the threaded spindle'. When the motor turns, a cut out cylinder interrupts the light . Obviously if the LED is

Hi Martin, I have taken your advice as in the previous thread. More investigation shows that when the 'play' button is pressed and the microswitch under the deck is held in the 'home' position the arms travel the length of the carraige so no belt slip or obstruction.(will not return though) Also, there is a small voltage across where

I find the LED by the transverse arm motor ? pulse counter? is open circuit part no 8330056 Anyone know what its replacement is?

I have wound the threaded rod by hand from one end to the other. There is no obstruction or sticking. The belt could be slipping but I don't think so. When it moves, it is very positive and always the same amount. I will check. The detector arm does not get as far as the record/turntable, It moves 2-3 cm from 'home' then stops about 1/2

This may well be a long thread but I hope at the end of it, I will have a working unit and an A-Z of fault finding & repairing one of these will exist for others to read. From the beginning, I got this deck in an unknown state clearly not working due to no tacho and no cartridge. These along with the service manual have been obtained and all the

I have answered my own question, for anyone else.., Push out the transformer from the bottom, slide the PCB towards the rear until its free, there are 3 latches which hold the panel in place. Push then to free the panel then the whole lot can come out. I would say impossible to get at from the outside without damage.!
