Great to see this Video Paul as iv just picked up one of these radios from marketplace and it’s in a bit of a state 😮 it very damp I think it’s been stored in a garage for years .. one thing I need to get for it is an aerial , but I’m going to leave drying out for a while before I start the refurd great fun…
Hi Paul I am a volunteer at the local Repair cafe and we offer a free repair service for resident's non working items and to try to divert them from land fill. I have been asked to repair a Robert R900 radio with a tuning fault and, as I suspected, the tuning cord has broken, Roberts will not supply a replacement so I have been trying to make one with narrow nylon cord and replacement eyelets to set the cord length. I am confident with the routing of the cord including the 3 turns around the tuning knob. Getting the spring tension right is a bit of guesswork. What seems to be happening is that the tuning stops when the 3 turns around the spindle do not wind or unwind neatly. They get jammed and so the turning stops. Any thoughts? Is there anything special about the cord itself that I have missed? Any help appreciated. many thanks Roger H
As usual a very enjoyable video. I would love to see you alining one of these radios, unless you have in another video. Thanks for sharing, take care. Terry
Thanks G. I get it, these radios, 40-50 years old, they've had a life, and something's gone wrong, and the user has tried to fix it themselves. I guess on this one the battery snap had been removed, and replaced with some other battery arrangement... PP3 snap / AA holder... and then removed itself and used on mains only.
Ey Up Paul I'm catching up with videos, nice set the R900 looks like an early case one , I didn't quite get all them bridges you did but hey ho your the Roberts guru How ya doing? Best regards Shaun
If Roberts current owners made a modern day internet DAB+ version of this beauty, I would definitely be willing to pay £200-£229ish for one like this or in the dark blue I've seen these in. Especially if they use the same retro "R" badge and not the incorrect signature logo like on the Rambler BT Stereo model. 👍
Depends on the country of origin of the transistor radio really. Those imported from Japan, USA, Germany, and even the USSR in the 1960s usually had VHF up to 108 Mhz. Most British built radios went up to 101 Mhz in the 1960s, and 104 Mhz by the early 1970s but there were exceptions eg: the 1966 Roberts R700 went up to 108Mhz. It all boiled down to British licencing criteria in force at the time I suppose, and available broadcasts at those frequencies. Here in the UK, the police used to transmit on FM around 100MHz until the late 1980s... I remember in the 1970s import sets to UK having up to 108MHz and able to hear Police and Fire brigade. The "official" limit at that time in UK was likely 104MHz, but unused above 100MHz till Commercial Radio started on VHF in UK.
Well i know nothing about the modification, i only have a hacker rp38 and it's perfect lol . Was the capacitor swap around to give a better bass sound?, Changing the speaker coupling cap? Mains or battery, Nice :-D
The modification reduces the inrush current which had a habit of killing the power switch... purported to have been caused by using a mains lead with a battery installed. RP38 is a brilliant radio... for a Hacker... 😁

Nice fix Paul, hope to see you reach your 1k subscribers.
I hope so too! - it'll just open up other positive possibilities for me.
As usual a very enjoyable video. I would love to see you alining one of these radios, unless you have in another video. Thanks for sharing, take care. Terry
I can do that one day soon Terry. It's now on the list!
@@Codeeze many thanks 😊
Nice work. You do wonder what - more probably why - people do to these radios.

I didn't quite get all them bridges you did but hey ho your the Roberts guru
How ya doing?

OOOH! Dodgy caps, broken wires, loose screws... factory original mate, fully working innit!
Thank you (:

So, which was the first radio featuring the full 88-108 MHz? Was it this one?

@@Codeeze Thanks for the info, quicker and certainly more informative than Google! 😉👍

R600s are good radios.
Yellow ones in particular...
