Summary
[edit]DescriptionRevox B215 - implanting signal relays 04 - implant in place.jpg |
English: Revox B215 cassette deck - deep modding - impanting signal relays in place of CMOS switches in the playback channel. Here is the implant daughterboard with all wires soldered in place. I preferred to mount relays in sockets, just in case (and because the aliexpress parcel took more time than expected...). The three LEDs (not really necessary) are actually on with 1/2 mA current in each. As expected, the existing 5V CMOS logic control signals are more than enough to fully engage the ULN2003 relay driver. The relays coils will operate at around 7mA current each, no big deal. |
