Thank you for making the video and posting onto KZread. I would like to you make a video replacing blow capacitors on circuit boards. I guess in my area where I live there are no adverting service tech. within 100 miles that would service analog tape decks.

Qual é nome da marca desse conversor? E porque não conectou direto na televisão 📺 para vê se pegava canais mesmo?

@GoranDzambazovАй бұрын

The converter was manufactured by the Ei Niš factory, located in Niš, Serbia, in the time when Serbia was part of Yugoslavia. In absence of TV stations that use analog terrestrial transmission, I'm using a setup that consists of a television pattern generator made by Grundig (as a source of the UHF signal), the Ei Niš UHF to VHF converter (connected between the generator and the TV) and a Samsung TV. I hope that this answers your question.

If insteed of 4.7 V Zener diode we use TL431, which, acording with the datasheet is termal compensate?

@GoranDzambazov3 ай бұрын

Yes, an auxiliary negative voltage source with TL431 or 7905 provides better line and load regulation, and better temperature stability than a simple Zener-diode.

HELLO, WHAT IS THE REASON I COULD NOT MEASURE THE OSCILLATOR IN Hz STAGE WITH UT139C MODEL MULTIMETER? UT61C MODEL CAN READ 32.768 FREQUENCY VALUES. IS IT POSSIBLE TO MEASURE Tuning-fork crystal used in a modern quartz watch WITH UT139C?

@GoranDzambazov5 ай бұрын

The possible reasons could be a very small amplitude of the oscillations or a non zero-crossing signal at the point where you do the measurement.

Hi, I have one UHF Converter in my collection at home. It is of Czechoslovakian manufacture, type: Tesla 4952 A. It was on our black and white TV of Czechoslovakian manufacture Orava 132 until 1981, when my father bought a then expensive colour TV. Nice and interesting video.

I purchased a budget set of speakers a couple of months ago, the Edifier R2730db (2.0). These are the first actual speakers I purchased, so I am not very knowledged when it comes to the technical aspect. In general, I am very pleased with them, considering their price! However, I do notice a little issue that bothers me. I am not quite sure whether this is a normal, or whether there is an actual problem here (and if so, can it be fixed? perhaps I did something wrong). When the speakers are on, but nothing is playing, I can hear a pretty noticeable sort of noise coming from the speakers. It sounds pretty much like static noise, just a lot of buzzing really, somewhat comparable to a condenser microphone that produces a lot of self-noise. This happens on all connection types I have tested; bluetooth and the two line ins (CD-player or USB audio interface). When you turn up the volume, it gets worse, of course. When you turn the volume up completely, it is pretty bad and impossible to listen to. But even when I watch a KZread video on my computer connected to the speakers via bluetooth or a USB audio interface, at what I consider a normal volume level (it might even be on the lower side, as I cannot stand loud sounds), I can still often hear the noise through the other sounds that are playing.

@GoranDzambazov7 ай бұрын

Hi, The noise issue you described does not seem normal, however, it would be difficult to assist you in isolating the cause of the problem without too much involvement. Perhaps if you can make a video recording of what you described, so we can hear the noise and get a better overview, then either I or someone else could give you some suggestion. Best, Goran

Did you strip out a screw head because the nut was glued? And replace the screw, that you painted at the end?

@GoranDzambazov8 ай бұрын

I'm trying to recall, but the repair was six years ago, and now I'm not sure what I did exactly with the original screw.

@mguerramd8 ай бұрын

@@GoranDzambazov One screw I would like to remove is glued. I nearly stripped the head. I’m going to try to remove the glue with the soldering gun tip! I was told this speaker was buzzing quite badly but I never turned it on to listen. I just disassembled it and recapped it. The caps were obviously bulging and leaking. Well, it’s not buzzing but there is no sound output at all. The woofer and tweeter both work though, I bench tested them. The led on the volume control lights up and I have 21 volt power on both sides of the bridge rectifier. I really know nothing about electronics, just dived in to try to fix it with the help of some yt videos. I hate to be a “parts swapper” but that’s the level I’m at right now. I hope to learn electronics and be a better diagnostician soon.
