Quick update: I had some time last night to fully restore a spare F707 PCB. I did the usual stuff, as reported above. Well, it did "something",...
Sorry for not mentioning this: I had already switched back to a thinner belt at this point. It‘s not that. With a 0,8mm belt, I can actually feel...
Thanks! That AliExpress ad is unavailable in my country (Germany). I am aware of the FixYourAudio-offer. Maybe I‘ll try that. By the way, I made...
Thanks. I am a regular Jauce buyer, so I am familiar with the general system. I might try this out some time.
Thanks again, @Valentin. I replaced the 0.6mm belt that I indeed had with a 0.8mm one and even though torque is now noticeably improved, the issue...
Just to complete the story of this repair, as I could only now return to it. I eventually convinced myself that the cause of the bleedthrough...
So, it is only now that I have been able to pick this up again. I eventually changed the solenoid, but to no avail. I also replaced Q10, the...
@nutronic, it's been a while, but I have only now been able to revisit the old F707 project again. I just wanted to report back that I did...
The FX707 is a different device. This tutorial does not apply to this model. No-power issues are usually fairly easy to resolve, but you will need...
@Seb, while the issues sound familiar, they also seem to be quite different from mine (an R707, not an F707). Note that all F/R707's need recaps....
Thanks very much, @nutronic! I checked mine and found several of these vias blackened. I could not be bothered with testing them – I found that...
Thanks, @Shaman32! I have in the meantime decided on a spares unit which is on its way, so I won't have any need anymore.
Thanks for this very valuable piece of information, @Valentin! I guessed as much from my testing the mechanism manually. Indeed, I managed to make...
I might need some help with this from someone who knows the Alpha-mechanism better than I do. This AIWA HS PL55 that I have here does not do...
I just received an NOS, in-the-box AIWA PL-303 in mint condition and restored it over the last few evenings. The restoration went fine and the...
I am looking for a spare charge port for an AIWA PL30/303 as shown in the picture (the component as such as it is soldered onto the board,...
Excellent detective work, @nutronic! I replaced all SMDs right after I got my F707, but this was at the beginning of my career as a tinkerer, so I...
Many thanks for this meticulous and precise report, @nutronic! This will come in handy when I get to working on my F707 again – which will,...
Thanks for the hint! I hooked up my converter to the scope tonight and took it for a spin. Unfortunately, I do not seem to be any wiser–yet. It...
Great news! After reading your post, I was going to suggest you do exactly that. 17 windings seems manageable. Unfortunately, this does not seem...
