Good old analog servo circuits.

@@12voltvids yes. :) In fact when I did my test after apprenticeship and got my degree it was a CRT tv and a VCR I got to work on. Sadly just a VHS deck. What they did was put a tape on the head used for tracking. lol. Strangely enough only 2 of us out of 12 made it to get the degree. Just show you can’t read your way to electronics. There must be an understanding of what make this and that happen.

Interesting thing about this player is it will playback beta 1 speed recorded in 6.0mhz super high band.

Obviously sanyo convinced them that the problem was fixed.

Light blue. The bad ones are light blue made by sanyo.

Some LEDs are well filtered, some are poorly filtered. The poorly filtered ones might also work.

Led do slightly, but its more of a fade between the power pulses. Fluorescent on the other hand Is a pulse light source. They light up during the power cycle and extinguish completely during the phase reversal. So you get the strobe effect. It only works with magnetic ballast. Early compact fluorescent had magnetic ballast. Then they went I high frequency electronic ballast. Those don't work.

Nope the servo is hunting. A bad tape with a damaged control track could cause capstan servo trouble but not drum.

@ilanuriel2573 sanyo did supply some average caps around 1982, notoriously the PAL sl-c6 equivalent as well. And I suppose Daves done heaps of these SL-HFs to even (say blindfolded) without a manual figure where the servo circiut would roughly be then track it down.

It it didn't have those known bad sanyo caps i would have rocked some pots. However after having changed thousands of them on brand new machines that had not even made it to the store for sale yet back in 82/83 when I worked for Sony, when I spot them I am on high alert. That was the symptom back in the day with servos that would not lock up just like it was on this one so seeing the symptom and seeing those blue Samuel the illumined solid caps That was the symptom back in the day with servos that would not lock up just like it was on this one so seeing the symptom and seeing those blue sanyo aluminum solid caps, They just had to go and as you saw fixed the problem

Of course they are leaky. Those are the sample / hold caps.

What? You mean you watch it at less quality than I produce at.

@12voltvids watching videos online yes i turn it down to 144p to save internet data except for detailed scene's I notch it up.

​@@12voltvids The video codecs YT uses getting worse and worse, they are not optimised for old CPUs. Once I had a Core2Duo E7500 CPU in this system, and in 2017 it was able to play back 720p 60fps YT videos flawlessly, it was marginal but mostly watchable at 1080p 60fps with occasional frozen frame issues when the scene changed. A few years later after a browser upgrade I couldn't watch the very same 60fps videos with it, they turned into slideshow at 720p 60fps. I changed the CPU to a Quad Core Q9550 about 2-3 years ago, it was flawless with 1080p 60fps videos then, now it's struggling with them, I have to watch 60fps videos at 720p again, and even at 720p it has the occasional freeze frame at scene changes with some videos. I wish developers were not so lazy (and/or servants of hardware manufacturers to boost sales by intentionally making code that runs bad on older systems) and optimize their code for older CPUs too. This CPU is old, but very powerful, it just doesn't have the latest instruction set. I mean if it was able to do something 3 years ago, and now with the newer versions of the same codecs it's struggling, I would not call that development.

I did and people bitched about that too.

​@12voltvids the poor bitches what a demanding audience wants introduce them to a 78rpm cylinder with tinny horn

Mmmm i want a burpy

Thats just too bad isn't it. If you can't handle the sound of a fan running in the background then you have bigger issues. If I turn the ac off it gets to about 40c in here. Even with the ac on it is still bloody hot.

@@12voltvids i can understand the AC when its getting Hot but the AGC off your mike increases the sound off the AC when the is no comment from you.

Please check the post on KZfaq and you will hear the issue

I watched the video on KZfaq as soon as it posted and it sounded fine to me.

That is a youtube issue. My levels are fine and the background noise does NOT increase when I am not talking. It is quiet in the background. KZfaq choses to apply AGC and level out the sound. i suggest you send youtube a message and tell them not to do it and see how far you get. It annoys me too because sometimes the radio playing at the neighbors gets boosted to the point that it draws a copyright match. Anyway i am not doing any work in a shop that is over 40C and that is how hot it gets. When it is 30 outside the shop is unbearable, I have to have the AC on or I can't work. I would rather not use it, because I have to pay for the power used, but I am also not working in a dangerously hot environment.
