How many watts rms per channel? I heard one man say he had changed capacitors many times in amplifiers and no better sound quality.Then he said he used audio grade capacitors I forgot the two brands he said and wow the sound quality was fantastic!
I love how ppl watch this video and then tell you that you did it incorrect after everything is working correct or they start askimg questions even though they didnt watch the entire video yet haha! Thanks for the great info
The color of the wires doesn't matter, it just means the left, and right channels sre crossed. You are not going to get great sound out of it,because it has one watt output, and small cheap speakers. Ite set sold around $25.00. You will not great sound, if you want great sound, get a Magnavox!
Hola amigo, tengo un radio igual, solo que el transformador se daño, que valores de voltaje deberia dar en la salida o secundario, me podras dar ese dato para poder adaptarle uno.
Hola. Transformer has 2 secondaries. One center tapped winding provides the +28VDC, & -28VDC. out of full wave bridge D901, D902. #2 is 15VDC, out of D903. (2nd. winding). So the transformer will be less. Divided by 1.141. I believe. 20-0-20 secondary gives 28.2VDC So 19-0-19, a good guess for 28 I believe. #2 for the 15VDC, 10-11VAC x 1.414 for that. Hope this helps
I do not. There is very little info. available on these. This one is still "shelved" at the moment. I since got a 2nd. from the same owner that failed in the same fashion, shortly after this one. I now believe the 8-pin op amps are prone to failure in these. Thanks for watching!
I'm messing with one of these. I got it and one of the issues was the tuner string has fallen off. I'm not sure why but it seems to be intact. I found an old manual online that shows the routing but when I put it on that way, it seems too short. It won't give enough wraps around the tuning drum and that seems to be causing it to not be able to move the dial through the full range as it will bind up on itself it seems. It seems as though the string is too short but the manual called out a length and it appears to be the correct length. Do you have any thoughts on this? I didn't see a great view of this in your video but I saw enough that I'm pretty yours is getting another wrap around the tuning drum. Thanks!
The best batteries for radios is the blue panasonic carbon-zinc batteries. I don't leave my radios without batteries in them. Radios should be ready to go with minimal fuss. Leave the batteries in them and turn them on when wanted. Though the blue Panasonic batteries are not the most energetic, the NEVER leak.
7:40 Take a piece of paper and cut a 1/2 inch length the whole 8.5 inches. Steep the 1/2"x8" piece of paper in regular white Elmer's glue. Then, wrap that piece of paper around the shaft (post)and let it dry in place. Works every time. You can also use newspaper rather than regular copy paper. The newspaper works well and is easier to wrap in place. Glue soaked paper is much stronger than any glue when it comes to broken plastic screw posts. I've fixed many of them this way.
Good visuals of the parts. It was very helpful. I have a Panasonic with the same problem and the same solenoid and rotary switch and cam mechanism. The brass forks on the plunger were bent obliquely when I opened up the unit. So, your shots of it were a big help for me to see how I need to bend it back to form. I have been having a hard time getting that part to properly engage with the cam. At least now I know how it is supposed to look! Thanks. I couldn't find your video in a search on RU-vid. I found it on a Bing search. That tells me that the RU-vid algo rhythm has problems. I miss the old days before Google bought the site and when you searched for something, you got a ton of videos related to your search topic. now you get only a few and the rest are related to your watch history. How frustrating!
It can’t be center-negative without being DC! ;) A lot of older Japanese electronics don’t come with the power plug and expect you to use batteries. The reason center-negative was so common in Japan decades ago is because you could use the switch in the barrel jack to automatically disconnect the battery… no microcontrollers or chips to manage charging and power source. Because Japan uses both 50/60hz in different prefectures they needed to design electronics to be agnostic of line frequency, so they made more DC stuff several decades ago. Since they were making most electronics DC, they saved even more when they could eliminate the adapter and use batteries, which is how they became the world leader in battery powered portable electronics by the ‘70s. Yes, Brother and Panasonic are Japanese. ;)
Oh, this unit was passed to a new owner some time ago. It's probably in the 16V AC range if were to guess. Maybe start w/small AC voltage, & work up from there. Thank you for watching!
Belt broke, searching for proper replacement. The Amazon: M-Tronics Replacement Turntable Belt for Emerson NR-303TT was too loose. What a pain. A simple rubber band might be enough for this cheap find. Still have to locate an appropriate size.
I am 64 years old. When I was 12,13 I worked at an appliance store in pgh pa. 1:00 an hour. Our console rca broke I saved up the money to buy our family an ER415 60% solid state. Couldn't afford the XL100 I remember the model number because I worked hard to buy that. I also bout us one of the first Litton microwave ovens. Avocado green one single nob. And myself a Sony HP 310-A stereo. Good memories.
Mi televisor lc 320 em 2 despues de encendido trabaja20 o 30 min bien luego le salen unas rayas verticales en el extremo derecho como puedo solucionar ese defecto gracias
I have a Brightmond Company Limited "MEMORY II PROGRAMMABLE SWITCH BC800E" for which I have no instructions. It appears to be an in-wall timer switch of some kind for "Incandescent Lamps Only, 300 Watts Max". One black and one white wire emerge from the back of the device. On the front is a single push button above a slider. a single red led is located above the button. I have scoured the internet and as unbelievable as it may sound, the only reference that I have come across to BC800E is the reference by jonathansanders4735 in this comment thread. If I recall correctly, the device was also marketed under the Intelectron name. Does anyone else have such a device or the installation manual and/or user manual?
Just curious, but where the heck did you find a schematic for your 750? I picked up one of these units yesterday but can't find a service manual for it anywhere. Thanks!
I have a SCT33 that won't play. Someone have me 2 back in the mid 90s where the tapes won't play. Someone I knew them fixed them but the problems returned about a year or 2 after the fact. When they were working, I had to play a tape on it for 10 mins before the speed would get up to proper speed. Can these problems be fixed? Wouldn't mind seeing if I could get my one unit up and running again.
Great work on this classic! I also have one and am looking for a schmatic and can't find one. Where did you find yours? never mind, i got it at the end of the video. Thanks for recording it. I really like this unit. Enjoy it!
great store, a little to pricy thou. thanks to fleabay a $5 cb goes for 30+ now and total junk 23 channel and you have no idea if it works. ill be glad when things get back down to fair prices..
I wonder who made this radio for Emerson. It's possible they could have made it in their own Japan factory but I suspect it was made by a subcontractor. Another video of this radio shows multiple different component manufacturers names inside. It was top rated by Consumer Reports in their 1970 tests of table radios.
We need to know how to lift the turntable platter out of the cabinet. It catches on the slot that allows the turntable to protrude through the cabinet.
I have this turntable. The problem with it is that when you touch the speed buttons, the light comes on and it begins to function but as soon as you release your finger, they stop working. This has always been an excellent turntable, and I like the fact that you can adjust the speed. Always worked very well.
Took one look at one when i had a shop yrs ago told cust life too short to to work in that thing outputs were shorted his speakers were probably bad too which always overlooked
So many towns in Wisconsin that celebrate Oktoberfest and they are run by mostly German Americans who know how to party too. Just one state north of me and no language barrier. You should see the tractors they have there!
Nice. I have a 750 i scored needs light but everything works. Am/fm i dont get much... but started with nothing and slowly getting channels despite being fuzzy. Thinking itll get better over time... the system is otherwise nice clean and loud for watching VHS and the record player. Nice video.
