Marconi R70 1957 record player
Good morning
I'm having problems with a Marconiphone R70 Record player The drive isn't working On removing the turntable the rubber intermediate wheel seems to be worn On pushing it to the motor spindle I can make it turn but it doesn't seem to be connecting with the turntable Also someone has tried to replace the cord between the speed control and the intermediate wheel I'm not sure if it is the correct length Does anyone have such a thing as a spare intermediate Rubber wheel Also can someone let me know what the length of the cord should be Photos enclosed Thanks very much Sharon |

Re: Marconi R70 1957 record player
You are unlikely to need another idler wheel. The surface of yours could be lathe skimmed or carefully roughened with a rotary sander to create more abrasive contact with the platter inner rim. That wire arrangement looks like some kind of bodge and ideally you need someone who may have one of these players to compare it with. The idler wheel tension is usually provided by a spring.

Re: Marconi R70 1957 record player
It's an unusual record deck - another one of those 'own brand' EMI types.
A quick google search tells me that the speed control is cable operated by a steel cable. You would think that there should be some sort of spring arrangement to hold the idler in the 'drive' position. An examination of the mechanicals should soon indicate how it was originally intended to work. I've never come across one of these decks myself. |

Re: Marconi R70 1957 record player
I have just had another look at the R70, it's only just working on 78 but none of the other speeds work, I replaced the old mono pickup cartridge with a BSR X5H
The sound from the speaker is fantastic I've found someone who can restore both the R70 and my old HMV 78 Autochanger |

Re: Marconi R70 1957 record player
You were very lucky to be able to find a BSR X5H cartridge, a very much sought after item. This record player uses an 8" x 2.5" so-called "slot" loudspeaker, primarilly used in a vertical orientation at the side of the tube in 1960s TV sets.

Re: Marconi R70 1957 record player
Have just borrowed the attached image from an old thread for illustration purposes. I think it's the spring described as the 'jockey wheel spring' that's missing. The jockey wheel would more often be called the idler wheel these days.

Re: Marconi R70 1957 record player
BSR X5H Cartridges often come up on Ebay,
I just happened to have a spare X5H in my spares cupboard, Edward Thanks very much for the illustration, have you a pic of your EMI, Alan |

Re: Marconi R70 1957 record player
I have had the Marconiophone restored, by Norwich Restore, he has done a brilliant job, it's like new
I'm going to send him my old 1940s HMV EMI Autochanger to see if he can sort it out |
