Take all the time that you need! It is a pleasure to watch you work and to hear your thoughts and insights as you go. You owe us nothing! We owe you for relaxation and joy that you share with us. Take care of yourself, your family and everyone that you hold dear. Best wishes!
Brings back fond memories watching your videos. My Dad was a manager at Lafayette Radio Electronics (LRE) corporate stores in Massachusetts and Rhode Island. He was there to liquidate the last few stores. I remember all of their stereo lineup in the sound room. I have a few hardcover store catalogs as keepsakes.
Blimey, you're my favourite guy on youtube. I find it sad that people get offended by anything you do or not do. Absolutely love your videos and always appreciate the time and effort to produce them. Peace, joy and happiness from the UK!
I appreciate your instructional videos Tony ! I own several Lafayette pieces as well several Sherwood receivers. Please keep it up. Thumbs up ! Congrats on the grandchild too !
great video! lafayette! great memory of my first component system in 1967 (9th grade high school) which included a lafayette integrated amp. i love your videos. thanks! stay safe and well everyone!
Hi tony your channel is one of the most entertaining and tutorial Chanel i ever came across keep up the good work and may you and your family stay safe Mike
Tony you alright. We have dumped our cable and do nothing but learn from people as yourself and even if I don't have clue about what your talking about,I still find it very interesting and sometimes helpful as I have for about two years now,been refoaming old speakers. A grandpa? Isn't life grand. Thank you
Tony, thank you for the videos that you share with us. Thank you for your time, knowledge, and experience. Learning how to fix and restore this kind of equipment is the main thing that I wanted to learn how to do since I was five years old. I took electrical wiring and motor controls in high school and twelve years later I went to college and earned my undergraduate degree in I.T. The things that I have learned in highschool and college are great and invaluable, however when it comes to my biggest interest being the audio gear well I have learned more from you and a handful of other people here on youtube. Tony I can't thank you enough for what you have shared.
Dear Tony, great introduction. Amazing how you can still steel enough time from your busy schedule to do such detailed videos. Keep it up. Greetings from Germany - stay healthy!
Big "thumbs up" and deepest respect for your preface, Tony! Thanks for that nice attitude and of course you sharing your knowledge and experience is *very much* appreciated!
Thank you for your position in relation to sharing and not involve money on this. I think this is the best way to enjoy it. Thank you for you very detailed content. I'm a long time subscriber. Please keep it that way. I going through the books you said would be nice to start with. Stay safe! Cheers from Brazil!
A Year so ago I did email you concerning a tuner I was trying to align I don't think you even responded And I was not offended in any way ..Being in the auto repair industry I also get many questions on how to repair something ,Although I try to help, trying to fix something over the phone or in a email is all but impossible...I even had my big brother who is an electrical engineer come over and try and help but no joy, it highlighted how specialized radio is. Watching you very informative videos and dumb luck I was able to somehow align the discriminator to 10.7 MHZ which was the issue using my oscilloscope .. I was able to finally align that tuner and convert it for use in the USA as it's from Europe..My big brother couldn't believe it.. I very much look forward to your posts, they also highlight the use of equipment and how one can use what they have to get the job done. Keep up the great work, your a great teacher..and I look forward to your next posts
Thanks for this video Tony. This FM stuff really fascinates me. All those adjustments seems complicated, but you make it simpler. Glad I resisted the urge to tweak any of those coils when I was a teenager! Without test equipment it would be a disaster.
Well explained video on tuning an FM band receiver. Enjoyed this very much. Almost everyone restoring radios seem to concentrate on AM radio tuning. Like the end about the test gear that is needed to correct the impedance. Didn't mention signal loss between the RG-172 and RG-8 (which is greater ) but that you explained by connecting 50 Ohm test gear and how impedance outputs you may be testing differ.
Thanks for all you do Tony! Have learned spool much from you since I've subscribed. I too have a "day" job. Haha! Sorry somebody may be giving you a bad day in the comments.
Please keep up your great work so that the hospitals can continue to do their great job. Hobby is not that important now. The health of you, your family and your employees is more important than anything else.
A couple of things Tony.... 1. The mismatch between a 50ohm signal generator and a 75ohm receiver input is minimal and would only result in a 2-6dB loss of signal which is almost irrelevant for alignment purposes. Most service manuals describe, or detail a "dummy load" which is not the same thing as a balun. A dummy load actually terminates the input circuit in an approximately correct load, whereas a balun provides a balanced to unbalanced, or vice versa, transformation to the correct, or roughly correct, impedance. 2. From decades of personal experience, I much prefer to align RF and IF circuits with an analog (metered) AC voltmeter across the tape out jack or across a speaker, which makes finding a "peak" or "null" much much easier than a scope. YMMV...Keep up the good work...!!! 73...Jordan VE6ZT
47:00 - I've heard that, for AM, if you 'stagger-tune' the IF stages (requiring a sweep generator), you get better low-frequency response in the audio?
No, by stagger-tuning the AM IF strip, you can widen the IF bandwidth, thus allowing more treble (better HF response) from the AM signal. But most people never bother to do that, due to not knowing or a lack of proper RF test equipment (sweepable RF generator, and optionally - markers). This is best done only if you have lots of IF gain to play with, such as 2 IF stages. Doing it to a single-stage IF is practically useless, and just lowers RF sensitivity. Plus the AM band is limited to 10kHz channel width anyway, with no inter-channel space.
Selling Mammography machines sounds pretty interesting. Do you have models to demo the equipment? After all it’s all about showing how clear the scans are! 😉😂
A standard signal generator only outputs a fixed single frequency. A sweep generator Starts at one frequency and varies or "sweeps" up or down to another frequency repeatedly (usually at a rate of 60 times per second) . The halfway point of that frequency sweep is called the "center frequency", which is usually set to the frequency that you are tuning the device to. For the FM I.F., it would be 10.7MHz, and would sweep between something like 10.6 and 10.8 MHz, for example.
@@xraytonyb Thank you I have a sweep generator but I don't know how to connect it with an oscilloscope. I plug the RF output key with my oscilloscope and I vary the frequency with my hand no responce occurs on the oscilloscope you can help me work with this sweep generator.thanks

You don't owe anyone an explanation. You're doing great and we must al respect your time.
Congratulations Tony on your new addition to the family

You're the best. It's a happy day every time you post, so don't worry about us. Thanks for making these videos.
Congratulations on the grandchild on the way. I have 3 grandkids. If I had known how much fun grandkids would be, I would have had them first!

As interesting and as educational as ever. Thank you!
Congratulations grandfather 🙏
39:46-40:26 - I sad commentary on just how LOUSY broadcast radio has become ;( (notice that I *didn't* include 'Band on The Run"[at 40:26] :) )

Unfortunately finding these videos is a bit difficult at times so I might ask questions that could be answered a video
32:16 - Ironically the SG-80 doesn't feature 'flywheel tuning', but the 'unit under test' does :)
59:24 - "And when you screw the cover back on, you add even *more* capacitance" :)
excellent video 👍👍👍
Thank you Tony. It was an invaluable video!

16:48 - From where do all those 'birdies' come from?
Ah, they're OTHER markers! What is the frequency-spacing?
Ah, the venerable 'newt stick'! :) (16:09)

Tony, Could you use a B&K 4040?
hey, buddy. I'm from Brazil. I have a question. You know the Golden Bell Ns2500 receivor? how about a good receipt?
You have 25.5k subscribers, what percentage of them case the problem for ALL of us to get preached at?
Ditto all current comments!
PLEASE.... Repair and/or restore or even modify a Sansui QR 500
Don't sweat the small stuff! Keep on keeping on. Great content,THANKS!
