I will try this thank you, I think you are described this part in the instructions:

Sorry if I failed to answer.Yes it is a LR-5555, I acquired from a guy selling online.t needed some love and now everything works very well except the radio. The hiss has gone away since I posted this...what I did is replaced the 10.7 ceramic capacitors and resoldered the volcano pods which were...

and they also mention a sweep generator! However I believe I only need to do this which doesnt require a sweep:

So I would like to learn and try to align the FM and AM stations using the instructions on my Lafayette 5555 receiver.After replacing the 10.7mhz caps and re soldering the volcano pods the frequencies are off, for example station 104.1 came in on 101.1..and anything about 104 is non-existent...

Hello, my Lafayette LR4555 has a few quirks regarding FM. 1) The classical station around 99.5 comes in perfectly, no hiss very clear. 2) Other stations come in OK but even when the stereo light is red there is a background hiss 3) I don't get anything else higher than ~104 4) The signal...

Thank you for the update I appreciate it. I have a MC-2000 and they are similar. I have been using ChatGPT to support my troubleshooting...sometimes its not reliable but other times ts quiet helpful. I upload the schematics or pictures of the board and it helps me along...maybe it can help you...

How did this end??

So lastly, I found the following pieces next to the oscillator, can someone tell me what this is?? The middle piece goes on top of the plastic base and the metal half disc goes on top of the middle piece??

I wanted to share with everyone a successful diagnosis and eventual repair. This is regarding a Lafayette LR5555 that was very dirty, greasy and overall not doing too good. Upon turning it on the relay would click on and off at random intervals. After fixing an obvious broken solder point and...

Quick question, the ceramic capacitor C17 (223Z) on the one side of the IC is soldered so that both solder points touch each other but on the opposite sice C18 is not...isn't that odd? I am skeptic with this board because seems like someone has been at it!

I appreciate all the comments and so cool peteCWA that you were there during the times of these awesome machines. Here is the wiring schematics"

Thank you. So there is one soldering spot (see in picture) that had the connection detached from the board. I removed the transistor now I can see why. It seems that some of the laminate is gone and about half remains. Is it OK to just go ahead as normal and solder as usual? Should I do a...

OK I hope that is it! I asked ChatGPT (haha) and the thing said the soldering points look old and also like someone has been soldering around and making a mess...there are three components soldered on the reverse side as you can see...

This is from a Lafayette LR 5555 receiver...prior owner seems to have done some soldering around here. The issue is that the relay clicks on and off intermittently, I can power the item on, no surge to speaker outputs...I am pretty certin the issue is with this board, look how dirty it is. It...

Well you are right, there was an indicator on the screen that showed a car battery with + and - and I guess I should have known but instead I measured the battery with my multimeter and it showed 9V that is why I didn't change it at the time. So to be fair it was my laziness...the item came with...
