Hi
This machine has a working 41056-1A tube amplifier for sound anyway. I have cleaned all contacts in the control box, mute realy and play control relay, however i don't have the mute function. There is no mute before the start of the record or at the end of the record. Also there is no mute if i scan the record basket, any suggestions. I have measure the resistance of the resistors around the vincinity of the mute relay and they are all are reading fine
regards

Have you checked the mute relay? It should work if you connect the coil to 24V.
It is energized if there is no record playing.
BTW: The relay in my 434 was also broken. I simply replaced it with a modern relay.

Thanks Marc.
was going to check the relay itself tonight, have to take out the amp and extend a few cables, as a matter of interest what specification is on the relay(ohms) and where did you source it

I used a generic 24V DPST or DPDT relay I had lying around. I don't know where I bought it, it's in my amplifier since 9 years and has been in the parts box for a few years. I think I bought in in a small electronics shop 200m away from my home smiling smiley
But these relays are common parts.

thanks Marc, have some myself lying around, just wondering was there a particular ohm range for the relay
