Finally the fourth unit is finished and works perfectly, better than new. It also looks like brand new, only a few minor scratches. I put the panels and other contents of unit 4 into the 5th in order to be faster to finish this one. Some issues were easy to solve like a complete recap of the CDM2 got it […]

First test of the battery pack EM5555
Finally I found some time to test the battery pack. For testing purposes I ordered a 12V 2.3Ah lead-acid battery which fits into the compartment of the original battery. Unfortunately I was not able to get a 3Ah but it will do its job. After charging the battery with my charger from my convertible I prepared a cable with the […]
1 + 1 = 1
I decided to mix up the parts of unit #4 and #5 to finish another one. Since there are some severe issues with the tape mechanism on unit #4 there are two broken switches on unit #5. However, this way I can finish another CD555 much quicker and can focus on the battery pack. Summer is coming we are going […]
Unit #5 and the holy grail
The last years I scanned frequently second hand shops online and sometimes offline to find spare parts or other devices. Whilst I give up to find a working device I think I learned a lot since last year to be able to repair the devices – and to be honest, four Sound Machines should be enough. That was the plan… […]
Unit #4 mainly working
I am getting faster with every unit. There are some neuralgic points that always fail. On the power supply it is definitely the transistor 7477 which was in almost all units broken or got killed during ling time testing. On the amplifier part one TDA2030 was not working – only a buzzing noise on its output. To check it I […]
Started with unit #4
Haven’t updated the site for a while since I was busy with many other things. However, although the cassette mechanism of unit #4 cannot be repaired – it needs new fly wheels – I decided to repair the other things. One channel of the amplifier is not working I guess the TDA2030 might be broken. The CD was working in […]
Video about AM/FM and amplifier panel added
Well, here is another episode this time with the am/fm and amplifier panel. Since this panel is working fine there is not much to do. I explain what failed on other units and put thermal paste onto the heatsinks. This helps a lot to cool the amplifiers down. https://youtu.be/_CosOQB9Aho
Unit #3 finally working, tape mechanism fixed
Finally unit #3 passed all tests and I used it for about a week. Even the tape mechanism is now working great. I finally got a solution for the white lever and the play/fast forward problem. All I need is to create another video explaining what exactly I have done. To ensure that the lever snaps back into its default […]
Final video for repairing the tape mechanism
Here is the second part of repairing the tape mechanism. Hopefully you find some tips and methods to get your tape back working. However, you need a lot of patience… https://youtu.be/5WmVaMAiEAA
First long time run of Unit #3 failed
A better product name than Philips-CD555 would be Philips-SMFH. SMFH as abbreviation of SoundMachine From Hell. The think drove me crazy the whole day. Whilst I was playing for hours yesterday, today morning it failed. I have to admit that after some hours there machine made a silent but hearable buzz which was not in the audio line and the […]
