- This is what you are looking for, to make IFTs yourself. Full details. You should create Factory-level IF Transformers if you follow tips in this video and you don’t have to buy anything, all materials required are available at your home such as old cassette-radios.
The green IFT appeared in the Project Board is for an SW Circuit. I will make a tutorial video to explain how to create this SW module soon. I have, actually, designed most of the vintage radios IFT setups, and I documented them in the Note that you saw in the beginning of this video.am willing. It is in Arabic but I am willing to make a sequel tutorial videos about it, only I need time and your support also. Stay with this channel and share it to others because this will give me more push to continue spreading this valuable information especially this channel is not for money, it is for people…
Stay with "Science & Technology" Playlist of this channel for similar videos.

Thank you. This is perfect. An elderly friend passed away and left me a number of things, including a gallon jug FULL of IF/preselector/impedance matching transformers from large to tiny. This will help me get maximum use out of them.
sorry for your loss
Your work is genius and brilliant! With completeness, you have added much information to help us all to restore old radios and get the IF transformers working again. Thank you so much for helping us in the restoration business. In particular I liked how you (1) indicated that SMD capacitors can be used to replace bad components, (2) found and modified a toy with rotary shafts and then add the turn down screw to hold all in place when winding, and finally (3), providing your wire-winding values. It is really a most useful video! Thanks so much!
Excellent work and wonderful Arabic writing
I've been looking for such a video for a long time. This is exactly what I was looking for. Detailed example of how to make your own IF cans. Thank you very much for this video, great work. I like the winding machine!!!!
...well, "if ya LOVE IT so much- then why don't ya MARRY IT?!"
Thanks and there are details hopefully coming on part2
Thank you brother.. Salute from the Philippines!!
you're very crafty, skilled, and frugal... kudos
me and a friend are interested in making IF transformers from scratch, i have a bunch of hi-f ferrites from old TVs and similar things, i'll keep an eye on your channel
Very good I like the bread board radio at the end well done 👍👍.
🙂 Good retourne pack ... Ben. i love Ham Radio ...
cool !!! in older magazines there are lots of projects with those transformer but here in europe they are nearly impossible to find, only some "new old stock" that sometimes came out in e-commerce sites.
Thanks a lot sir ,,please give us about FM IF transfomers details ,its very valueble,,thanks
Good ideas Thank you. However, regarding the small caps inside the transformer. I wouldn.t actually bother fitting them inside anymore. It is more trouble than help. I always put them on the PCB next to the transformer. This way they can be tested and replaced when needed ! Having the caps inside is a real pain. Just imagine having to change one of those inside require you to completely de-solder the transformer, disassemble it and under the magnifying glass install another and everything is so small you could break some winding ends in the process and you wouldn't even notice it and even worst, because you have to de-solder and re-solder back the transformer chances are, you could end up with broken (lifted) PCB tracks etc. No, is way too much trouble!
Hello! Ben, congratulations friend, I like radio frequency circuits, good idea to share your knowledge, thank you very much.
Me too, coming is more in this playlist.
congratulations. A fine job.
ابداع ماشاء الله
I have been making running transformer"s for a very long time"s which I also get it off older electronic"s bord"s liked old TV part"s old radio"s stuff liked this
عمل جيد استمر
I Did not know that IF-Transformers could not be bought anymore, but indeed found nothing on Digikey and Mouser. What dark times we are living in.
Yea, very dark.
حقيقة انا ... مهتم بهذا الجانب من موضوعاتك. شكراً.
Thanks for sharing ❤
Radio thời bóng bán dẫn.. dễ sửa và thay thế khi hỏng...
nice
Are all the windings on each ift the same
Super

Was part 2 ever completed?
👍👍👍👍👍
Hello, what about green,, brown, orange coils?
Friend, this coil I'm asking is the coil of Antenna L3 of the Sanyo M9830K radio, this coil was open all of its wire and it doesn't have that capacitor at the bottom can you give an idea of the number of turns of wire for me to wind it again?
Hello, Do you know type and values of the encased capacitors that those IF trasformers have?. Thanks in advance.
Some of them are 40 pf or 45, 180 and 170 pf it depends on coil inductance according to the purpose in circuit IFT is used for but for the radios I documented most of their patterns along with coils information in a note, so I think may be I will need to upload the information in that note. Use SMD capacitors instead of those encased caps, they are more stable and more accurate.
I have national Panasonic pocket radio rf 9.mw oscillator coil is dead. I'm trying to rewind it with new wire Primary/secondary.after completion mw responding clearly full scale, but different wave bands receiving. I guess wire gauge changed. Can you suggest? The coil in the metal case is the micro size.
Yes, full video about this showing more than 20 vintage oscillators samples. Hopefully will be uploaded soon.
@@afaifeem thanks for the reply. Looking forward for your reply.
Great job , can I wind the same of those to work as MW band RF transformer , can you help me with that ?
Part2 of this workshop will answer your request, not only that but will explain how to make any IFT for any purpose, at any setup and/or any frequency:

@@afaifeem I watched it , not what I am seeking , RF transformer is used as an output transformer in RF amplifier , it's tuned with a tuning capacitor .
@@hunk6019 The video I am meant is still not uploaded yet. It is part 2.
@@afaifeem I am waiting
How to make national 1007 pocket radio three ifts winding & pf number
There are videos coming soon how create them for an radio.
Kaise milega please bataeye sir
is it possible to overheat ferrite?
Not that dmages
Why make them instead of buying them to keep the demand alive so they keep manufacturing them? Or it will be like trying to buy if coils for say...a Hallicrafters s38 line of radios. Theyre not made anymore. Whatevers left in some old codgers barn or toolshed as NOS is all we have left. Nobody makes basketweave coils at all for decades either.
Assalam Aleykum! Does part 2 available?
Sure
@@afaifeem I am building the superhet like you build, and would like to know how to make yellow, white and grey coils. The red one (am oscillator) is already built. I would be grateful if you could share the part of the video. Shukran!
Sir mujhe chahiye i.f.t condenser redio k liye
Coming…
Sir mujhe chahiye please bataeye kaise milega

Brother I don't have those parts for IFT. I have some inductor chokes instead. Can those inductor ferrite cores be used to design IFT?
Yes, but you need to increase the round. Do ur own calculations.

Thanks for the replies! I am a radio enthusiast so can you kindly upload a video on how the Local Oscillator works in a Superhet radio?
Yea
ارجو التواصل معي عبر الاميل
Infos are missing on the design so your video is pretty useless...
For u at least.
