- Here I restore a Bush DAC90 that dates back to 1946, but can you believe it !! , another dead output transformer. I explain a bit more about rewinding, and the mistake I made, which can only be put down to lack of care and attention !!

Bad luck on the old O/P Tx again. What are the odds? You're definitely going to get very proficient at winding. Great video again.
Fantastic videos. Very enjoyable.
Well thank you James. All the best. Tony
Yet another excellent walk-through. Thanks for your videos.
Great videos Tony, any chance of a workshop tour? Thanks for the 13 amp fuse tip!
Glad you like them Kieth snd thanks for commenting. There really isn't a lot to see in my workshop other than what you see in the video. Just a very untidy rack behind me with the kit that you see in the videos.
The UK is a paradise full of mediumwave-transmitters!
Very entertaining and interesting video.
With my 100 metre longwire antenna I'm receiving all the stations from the UK on medium- and longwave.
That's good to know. I certainly need a better signal in my shed. Perhaps I should do the same
@@tonydurrant Yes, that's a fine way for good reception.
You need a thicker wire (could be isolated) for the antenna wire and one immediately connected to the earth.
I have mine hanging around since about three years... 😉
I recall I had an antenna just like that when I was a child and lived with my parents. In those days I built crystal sets. That was some time ago as you can imagine
@@tonydurrant Oh yes, i can imagine.
By the way: Thanks for taking your time to reply my comments!
Thank you for taking the time to comment
excellent another channel from the UK.
Yes great stuff
Hi Tony, Really love your videos. Is it not possible to buy vintage output transformers on say ebay or elsewhere rather have to rewind the originals?
Oh I'm sure it may be possible if you can find one that fits. I guess I just wanted a challange to see if it was possible
Nothing wrong with that Tony - made for an informative and very enjoyable post - thank you

Thanks Juan
Greetings: Again!
You show two different power outlet types on your long power strip (angled hot & neutral); while your dual switched outlet has hot & neutral in a straight line. Are they on different mains systems?
My shed has 1 ring main with loads of dual sockets all around it. (11 in total I think). The long 8 way strip is plugged into a socket to the right of the picture. So no, it's all the same mains system - nothing fancy
In a bit concerned why this model got no reception in the workshop when the others got something, at least on LW. Is is more susceptible to modern power supplies and the such like?
Yes I agree. It is concerning and this is something I have yet to get the bottom of. Having turned off everything in the shed, I don't believe it is interference from anything running. I think it might be that frame aerials are more susceptible to picking up low frequency noise within the radio than ferrite rod aerials, but I certainly don't know that for sure. Still working on that problem !
I find it easier just to cut card end cheeks for the bobbin. I found my Dac 10 suffered from interference maybe LED lights in your workshop. You should also change C21 they are highly stressed. I left a link in my other comment showing the cheeks
Hi Tony, Welcome to the UA-cam radio repair and restore community. Look forward to seeing more videos from you. I learnt something from this video and that is always a good thing to get from a video. I will echo Chris (@AllTheGearNoIdea) and say that you are welcome to give me a shout if there are any things I might be able to help with. I'm also a bit of a joker because a lot of videos are far too serious so you can often find me doing some strange things in my videos. I tend to fix allsorts, not just valve and transistor radios so strange things do appear on my channel. Pop over sometime and watch the madness.
Hi George. Good to hear from you and glad you got something from watching the video. Like you, I also tend to try and fix all sorts of things. I see it as a challenge to try and make something out of nothing !!
Nice radio any selling radios I want I'm from India
Looks like your breath is visible in the shop. Is it that cold?
Ah well, it was quite cold, but I have a fan heater which works quite well, but when making a video I have to turn it because of the noise !!!
... it would be useful to recap on why you’re not, in this case, using your chassis earth connection ...
Hi Fraser - good question. This is explained quite well in Part 1, but the bottom line is that the chassis isn't connected to earth, and you can't connected it to earth because one side of the mains is connected to chassis. You have a 50:50 chance of connecting the chassis to live depending on which way you fit the mains connector. This is why I am checking carefully at the start that I am connecting the chassis to neutral - not live
@@tonydurrant thanks Tony - great stuff indeed! I sold my collection a few years ago, although I still have one decent valve set to admire ... cheers
G'day Tony, I know you have just start these series of videos, which I'm enjoying.
I also enjoy David's video in restoring radios this is his link: ua-cam.com/video/HehqiOVo4UQ/v-deo.html........
I have few questions, is there a reason why you don't use a Variac? for high and low voltages? The dim bulk unit is excellent as you see on David's link on the Dim Bulk Control unit it's shows Volts, AMPS, Watts & FRQ/PF . Just food for thought in showing your video friends.
Be safe and enjoy our radios. God bless you and your family.
Hello Dennis. An excellent question. I am watching David's video now. I do have a variac which I use sometimes, often in combination with the lamp limiter, but the advantage that the lamp limiter has over the variac is the speed that it operates should the radio start to draw a high current. The variac will limit the voltage nut not the current. The lamp limiter will instantly limit the current, and as such, the voltage. I see David has a combination unit which is clearly the best of both worlds. Daviid's videos are excellent and I have now subscribed
@@tonydurrant Thanks Tony and sharing your ideas. Have a good day.
