So today we're going to start with a trade customers box of jobs and it's a Murphy ds602 from 1981. uh JJ silver were the importers for great Universal stores so it was done by the mail order catalog such as great Universal John Moors and the likes I think it was 69.99 so a lot of these were bought on weekly terms um use the Uniden type of power connector and the only real let down on these is the squelch which is wishy-washy so we need to just do a mic for this it's not come with one and it's not a mic I have lurking unless it is and I've forgotten what the pin out is so just looking at this list Murphy oh it say no it says it's cybernet or put the I was going to make a mic up in front of you but we won't standard standard as it comes anyway foreign so this is an unknown set it says protection diode blown needs testing it's been hand painted at some time but nevertheless a bit once sorting it'll get it you have to be where it self-tappers on these not the usual machine screws if these were lost it'd have to be probably tapped for M4 pop the lid off and he's unsoldering it's all Tatty that wiring so we'll we'll cut it short has no circuit diagram for these sets that I'm aware of it uses an lc7137 so there aren't really any surprises why somebody put a crystal filter in it well that can stay although we specialize in doing OEM original equip manufacturing repairs um as long as that's not wrongly done in other words when I test the receiver as long as it works um to a satisfactory level that can stay put rather than the ceramic type of filter which is this type of thing if you can actually see that I should have different color hands shouldn't I right check it underneath and if the protection diode really is blown it is and it's been bodged on the back you know he's so I'm not powering it up till we've sorted that out right so that's got rid of that one other they put in there I haven't got the foggiest so I'm not going to replace that this second I'm just going to remove it so that we haven't got the problem with them heat causing a short across the power line but you'll see me put one in later on in the video yeah I can see the two legs it goes upright I think we need to solder that up right so plug the mic in pull the test equipment into the aerial socket because of the extension speaker in which goes into the test equipment and then we'll find wherever the power leads gone today just use the crocodile clip I'm just current limiting this for now 9 volts 300 milliamps it's...
