Glad you liked it Andrew. Sounds great as well. Caps were well out of spec but it did still work. Probably should have got the modules out for a look as even though they have silicone transistors in I expect if they contain electrolytics then I may have to swap those out as well.
Thank you for the video! Could you please tell how to touch up the grill? I suppose it may be restored with some permanent marker, but is there a better way?
Do you have any info on replacing the mains power regulator in an r606-mb? We have one we’d love to be able to plug in and stop having to use the batteries! It doesn’t seem to work from a power lead but the battery power works perfectly.
I have a 606MB which has the same board as your 606, it has the same tuner module and the same two if modules. Might be a later hybrid, who knows. I think the rf tuner is faulty as it has great vhf but no mw or lw, not sure where to start with that.
Great video as always, really enjoying these. Quick question if I may? is there an easy way to date a Roberts R505 and a Hacker Hunter RP38a that you know of please? all the best, John.
Hi John. You can probably date you RP38A by having a look at Mark Hennessy's database via this thread www.vintage-radio.net/forum/showthread.php?t=81927 the the Roberts radio group on Yahoo states that the R505 would have been made Between May 74 - Jan 79
great job where did you get your speaker from and could you show me a picture of the wires on to the battery compartment of forgot to take a picture thank you for your help
Hi Robert. The speaker was the original one that I took out for testing purposes. The battery connections are shown at the start of the video around 10 seconds in. If you are still stuck then let me know and I will pull one from stock to have a look
@@Radiocruncher Hi Thank you for your Quick replay, My Roberts Radio is the R606 MB, I figured it out when I realise the speaker clips were small, and the other two were big lol, thank you once agian.
Great accent. I bought one exactly the same but in a sorry state. I can't even get to the batteries yet. It seems sealed from outside. This video also didn't show how to get to the batteries. Anyway I managed to get to the batteries. Amazing easy if you know how to. The radio itself is working but all the batteries have leaked extensively and have destroyed all the contacts. Mine is in maroon colour and the aerial is also intact. I wonder when they were made.
Glad you worked out how to get the battery compartment out. It’s just a lever from memory that you swing to one side. These were made in the mid 70’s. I have recently fully restored a maroon one so I will do a video of it soon. Thanks for watching. Regards Graham
Hi, it is really an honour to watch your videos. You are certainly a great communicator. As for opening the battery compartment, the hole at the bottom is for pulling the cover towards one end so the other end would have a gap to lift the cover.
Hi again, I don't think I can make use of the radio that I bought. I am really a beginner and this needs your expertise to create another masterpiece for us to enjoy. I also have a very old Pam transistor radio that I would like to gift it to you together. The Pam radio does not work, and I have not messed about with it at all. It looks all original.
Hi Farhad. That’s very kind of you. The Pam radios are very old and depending which model could even be the 1st British transistor radio. Drop me an email to graham@radiocruncher.com and we can discuss it further.
Once you have pulled the wood out of the way you will see a metal tab with a plastic peg at one end. Slide the metal tab over and you will be able to lift the battery tray out
Hi Vasilis. I have sent you an email. In one of my videos I show how to get one of these apart. I will send you a link if I can find it. Thanks for watching. Graham
You could try these rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F183576238996. The only other option is to buy a spares radio
I used mainly Vishay axial caps. It was a long time ago though so I can’t remember the values off the top of my head. The service manual with the original values is available online so just match the values as close as you can and make sure of the correct voltage

Nice one, I love the old radios they always sounded better than they do these days, keep up the good work.
Regards
Dave.
Thanks Dave. They do sound better and are easier to repair
Have a 606 MB and love it.So much better than digital radios.
We have a R606MB as out kitchen radio. They do sound nice. Thanks for watching
Great restoration!
Thanks Ian. It cleaned up really well. I remade all the solder joints so no reoccurring issues. It's a keeper👍🏻Thanks for watching
Super! That come out really well. Quality buffing :)

Thanks for Sharing 👌would you have a part No for the aerial ? Iv just done a refurbishment on a R900 and need a replacement 🙏
The aerial is no longer made

It doesn’t seem to work from a power lead but the battery power works perfectly.
It could be the internal fuse, a switching problem, transistors of the capacitors. As long as its not the transformer it should be easy enough to fix
It could also be the rectifier or zener diode as well

Hi. Sounds like it's an early hybrid of the later model. Start with cleaning all the switches. Then check the oscillator circuit for AM

Is there any chance to find the variable main tuning capacitor for Roberts R900?

Would be great if we can get one.
