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 […]

Merry Christmas
Merry Christmas to all of you. Christmas brought new speakers. Another modification and a huge improvement of sound. But the speakers need a case that fits better to the design of the Sound Machine. More later, in the meantime enjoy your holidays with your beloved.
Game over for unit #4
Well as described in my last post one fly wheel of the capstan was broken. It is impossible to get one and quite an effort to create new one.

There were several devices I had in history which I can remember that did it that way. I expect a difference in the current when the tape is at the very beginning and at the end of the […]
Tape Counter Button
It took me a while to design and print a button for the new tape counter. Whilst the first approach was working it was not so stable and too thin. From four prints I was able to use two. Need to figure out the best way to add supports for a better outcome. However, I had to redesign it. I […]
