Not even once in over 20 years of using compressed air, have I ever had that happen to me. That's really bad manufacturing soldering if that happens.

And it could probably only happen on SMD components. I can't imagine in my worst nightmare that TTH (Through the hole) leaded components would ever separate from the PCB like that.

I work on B&O, Philips, Grundig, Onkyo, Pioneer, etc. I have the good fortune to be able to choose the equipment I work on - only good manufacturers.

I guess if you had some Chinese junk, which hadn't had the SMD components soldered on properly, that that might happen. But you'd need to be using VERY HIGH pressure - over 150psi to cause that kind of damage. My compressor is regulated, and I keep it at 100psi.

Ok, since everything sounded fine except for the low drivers I´ll probably leave the capacitors alone this time. Let us know how your recap goes. Take some pictures too 😕

Change those caps, if you can solder it is a small job, and you will hear the difference. These caps are as old as your speakers and dry or on the way to be.

 

Yeah? Know of any who supply caps with the RL140 in mind (packs). Or point me to info on what kind of caps I need and/or datasheet of the PCB?  I make a fair amount of guitar pedals so soldering shouldn't be too big of a threat, although I have never worked with speakers before 🙂

Already ordered double-sided tape, cloth, new straps and spray glue. Looking forward to this! And if the a recap makes an impact on the sound and it is audible, then it is def worth it 😁

Will do my friend, now I'm getting excited.🙂 But will do one RL140 speaker first and connect them both to my system to check if I hear any difference... I do the same for my Penta 3.

Will let you know!

Definitely looking forward to hear about this Leslie. How far down the process are you? Let us know 🙂

Yes SMD, and Pioneer autohifi.. Allright, allright, they were left in rain, who knows how long time. But at the end I get them work again 😁

Ok, I dont have nowdays possibility to use compressed air, so I have to use what I have.

Now, back to splendid FInnish Nokia beer

Hi Per,

Nice pair of RL 140 you got there. I have a pair that is waiting to be delivered so I'll probably go and do the same refurb stuff. Cap kits can be ordered from Martin (Dillen). I guess that you live in Sweden? If so, I'm curiuos where you sourced the tape and the spray glue?

Regards,

Mikael

Hey Mikael, Thanks for the tip, I'll see if I get a hold of him 🙂 I basically ordered everything off Ebay since it was much cheaper than in the local stores here in Norway :)

I found some spray glue at Biltema, I have no idea about the quality, but I think I will give it a try. I havent decided on where to buy speaker cloth yet (Ordered , but not sure if I will use them). Let me know if you find any interesting and good looking cloth. What colour do you think you will go for?

Foam rings

In your link good hifi says RL 140 6" inch speakers, the RL 140 has 6.5" drivers, I used

Yes, you are right it says 6", I didnt notice that. Anyone got experience with the good hifi-set? Are the rings too small?
