Thanks so much for posting/sharing these videos! I acquired one of these with a package deal and I gave it to my son whom will be working on it to fix it. It does work but doesn`t move to the next songs.
Nice video Felix, I got one SL-5 like yours, is a 110v, but I live in Europe, and here is 220v, I think the people who I bought the TT they plug the TT to 220v and now even with a step down transformer there is no sign of living, can you please indicate me were is the fuse located in this TT? Thanks, cheers.
That is a really good question, and the answer might be a bit surprising. I actually couldn't remember seeing a fuse inside, and so I checked the service manual. It indicates that a small PCB for the fuse is located between the transformer and powerswitch. I checked my video, couldn't see it. So I then opened the one I have next to my desk. No fuse! So digging through the manual, it seems only XA models (220~240V) were fit with a fuse. But there is certainly a few tabs and a hole that looks like it was designed to accept something. So my guess is, if you don't see one in that location, it was never fit with one. With the scenario you have described, I would try desoldering the wires from the transformer where they connect to the PCB and check the transformer isn't cooked (you should get around 19.3V out according to service manual), then have a look at the PCB for any signs of damage. If you have a bench power supply you could try feeding in voltage to the PCB (ramp up slowly to 19.3V) and then check for signs of life. Check some easy stuff too, like the main axial capacitor (the big one!) isn't showing dead short across terminals. You might get lucky that a few input components died and sacrificed themselves and saved the board. I would guess that's the case, but without seeing it, hard to offer any more specific advice.
@@felix_da_katze Many thanks for the complete list of information, mine is just like yours don't hove pcb fuse, I have a bench power supply I'll try to connect with the main board, I already checked the transformer and it's dead, 0v on the secondary, I'm not a professional, I'm a curious person that likes to learn, just one question, I will desolder the wires from the output side of the transformer and connect the bench power supply on that wires, what is the + and - ? Many thanks again for the useful information.
If you connect the bench supply up to where the transformer was soldered, it wont matter the polarity. The rectifier should take care of it. It is possible some kind of over current protection was built into the transformer, but I think it means that transformer is dead. No matter, you best bet now would be to replace with a transformer than can take your 220V and give you 19.3 out, and fit that (once you've confirmed the unit is working of course). Best of luck! Any questions, I check here every few days.
@@felix_da_katze Thanks again for the help, I have checked the transformer and on the primary there is no continuity, the secondary I think is ok, I will remove the transformer and I was thinking of plugging my Variac with 19.3v AC to the 2 wires that go to the PCB, what you think? Sorry for my English, because is not my first language. Best regards.
Yeah, you should be able to do that. It is expecting AC, so if you have a way to give it AC, go for it. If you press the power switch and get a red light, you might be in luck. But check things carefully, and if you have way to limit current, do that too. I can understand you fine, no need to apologise. If any of my explanations are hard to follow or understand, let me know and I'll try again.
