Loop in the roof CW QSO with VK7TO
Weather has been shocking with damaging winds, I'm yet to go out side and reconnect wire antennas so decided to use the 40m loop in the roof. It works better than expected but I keep the power low. It is stood off the timber with long electric fence insulators. It would be at best 3m off the ground (in the roof)

Arlec grid connect plug, can we fix it?

Just a bit of fun to see if we can get it going again. I'd usually use new components but hey just something for the video. Some of the cheapest components money can buy in this thing.

This is mental....I have 3 of these , 2 that won't even power on and they are immaculate....they have been stored for about 5 years but were working when stored.. without batteries. I've got One in bits on my bench and literally can't find an issue...well not anything obvious....and you say these turn on.... I must be so unlucky ...... Currently chatting to Sennheisers to see if they can be fixed. I did notice blue corrosion on the battery terminals but as I said they weren't like that when stored and I religiously take batteries out after every performance..So annoying as they a bloody expensive to replace...got any tips of things to look out for....my third one works perfectly...go figure.....
how much does it cost?
Thanks for the nice video ! Are the Siglent SDS2XXX HD O-scopes MSO's ? Will they display time based and FFT traces at the same time ? Thanks !
The internal battery is a FB-NP-W126S. I replaced mine with a Patona NP-W126S 1140mAh
Hello Would you please reply me?
Hi There is some videos in youtube showing dell or hp psu hot plugs convert to bench power suply. They could run the psu hot plugs by connecting some pins but they just could run them to take a small curent not the maximum curent. Could you please tell me how to run my "hp 2450w hstns-pr16 platinum hot plug" and "hp 2650w hstns-pr42 platinum hot plug" into a bench power suply to take the maximum curent and power? Kind regards Kevin
Looks like an old dick smith keyer
It may well be. I actually found it in a cupboard when I moved in to this house.
Is there two version or what 🤔
A hd and non hd possibly
@@jordanclarke2996 no i mean the old one white and the newer one black with low noise floor of 70 ųvrms
Not sure sorry. Although I do vaguely remember the eev blog doing a video on a new silent scope might be worth checking that out
Nice video. I would have thought you would have replaced the equivalent transistor in the other channel as well?
I also have some amplifiers to repair that I can help with
Can you please write values of zener resistor and SCR gate capacitor? tnx
They are written on the paper towards the end of the video
Greetings from Argentina I have a crown xls 2500 which in its output stage has an NSS20201L Low VCE(sat)NPN And in Argentina there is no such transistor. Do you know if I can replace it with a normal NPN one? From already thank you very much
I have some quad lps but no quad set up but they do sound great on a stereo turntable
I have an crown xti 2002 that was doing the same thing at turning on but i also had All leds on both sides on. Can be detected on pc. So i turn it on,no fan,display on but blank and the leds are all on. Did you ever met this problem,or any ideea what should i look for? Ex owner claimed is an firmware error but didn't want to give more details
What the heck did you do besides probing around didnt see a fix
At the end of the video I said it was a boring repair video as after reseating the ribbon cable it came to life.
Hi
Can this work down to 5v?
Change the Zenner diode to suit your voltage requirement 👍
Muy valioso el video... Ahora no me queda claro cuando enciende bien el ventilador...
solo cuando levanta temperatura. esto para evitar que se llene de polvo
Hola, tengo exactamente el mismo amplificador y al encender muestra los led termicos encendidos,
Merci for this video.
What happened to the follow up on the mods?
There is a video on my channel for a crow bar circuit. Other than that for the time being I've stopped filming.
Hi. Thank you for the video. Do you have the service manual ?
Great work. I have a Rotel pre amp RC03, along with 4 power amps. Its been a fault free system for the last 24 years. I have noticed that the channel selector on the pre amp is becoming a problem. Its basically skipping channels after selecting. sometimes minutes after selecting the right channel. Can you recommend a easy fix, or is this a back to Shop or Rotel?
I think with protective earth, the charge of Ozone Ions is directly discharged at the Housing...
For the temp lowering fan, I am having the same issue. Thanks to your video, I need to check mine also blocked by the thick paper haha😂😂
ohhh re-seat…Thought you said reset
Wow! There’s water damage and then there’s ‘left at the bottom of the ocean’ water damage
Hi Jordan, I have one of the XLS models and in sleep mode the strobing lights give me the shits. Do you recall if they are SMD or through hole discrete led's? I'm contemplating covering them over or disabling them on the board (the front cover doesn't facilitate hiding the obnoxiousness of these). Also curious if you know what the power draw is in "Standby"?
God Damnit. Must have seated it wrong. It started to come on properly then shorted out and blew the amp. Be careful to clean thoroughly before replacing the cable, especially when the amp was left semi-outdoors in a shed or something and accumulated bits or rust or corrosion.
sent you an email with the subject line 'player piano'
Hi, I emailed about a week ago, it was just in relation to this piano project, if possible, I would really appreciate a couple of questions being answered. all the best. Adam
Hi Adam, I'll have a look out for your message this weekend. I get a lot of email and it takes quite some time to get through it all. Cheers
Not bad at all for one watt keep the good work up happy hunting VK4SD
Ive actually repaired a few of these in a very similar condition a couple of years ago. Eventually got them to work. had to make a few jumpers on the damaged traces.
I have the xls 2500 (earlier version) and it exhibit the same issue with that amp in this video. The only difference is that i displays "error 404". I don't know what is so i tried to fix it by plugging and unplugging it multiple times until i hear the "double click" and then it works again. But sometimes when it doesn't work i just go back to it some other day and it's working again. Is it the same issue with the one on your video or something else? What does "error 404" mean. Hope you can answer this. Thank you ao much.
Hi. I'm having problems with 3 of 4 HP DSP 460 EB. I'm building one power supply 24 voltages basing on 2x DSP 460EB. They are in series connection and one of them were modyfied. Ground connection on PCB was broke. This is oportunity to series connection without short circuit. But my problems are DSP who just "give up" One day they working fine but next day they are death. What I can do. How I can check what is wrong with them. They just not starting with green LED light. I'm bearing "click" while connection to the power cable but nothin really is going one. Reistors are soldered between 1 and 4 pin. Can You give me some advices?
I prefer the XLI
I was hoping you'd connect up one of your expensive pieces of electronic equipment to the power supply, then short one of the PSU finals!
Im buying a similar unit (probably exactly the same inside.) Definitively going to check it and add earthing if missing.
How about now??
Thanks For recording that Jordan. You can make it public if you like.
Seems like a relatively easy bug to fix especially as you've shown how to reproduce it so well. Thanks for the headsup.
Sir crown xls 1000 powe,.r supply not taking on please help me
Buy the keithly if you can afford it. Not even close.
Totally agree the keithley is fantastic. Fortunately I own both
Kind of surprised it hasn't even arced
Thanks for the video mate! Where can i buy one of the voltage regulators for this? Thanks
Not sure what country you are in but I use rs components or element 14. Cheers
@@jordanclarke2996 i’m in sydney. Think i found the right part on the Jaycar website. What would i need to remove it? I’ve only got a soldering iron if that’s helpful haha
@@robinluo9038 soldering iron will do it becarful not to put too much heat in to the board and damage tracks. Have you checked the reg is the problem?
