hello again…

i ordered the parts for MidiBox8+JDMprogrammer but some of them are not exactly as i ordered, please take a look at this and tell me if i can use those  :

  • ALL the el.capacitors are 25v (except for the 2200uF for the power supply - it is 16v).

  • the “74hc00” is a “74hc00 p”

  • the “cny17- 2” is a cny17- 1"

  • the “bc547 b” is a “bc547 c”

  • the 8.7 v zener doide is a 8.2 v

tell me if its ok to use them or not - or should i do any changes  ???

  • ALL the el.capacitors are 25v (except for the 2200uF for the power supply - it is 16v).

The 25V are caps ok. The 2200uF/16V cap is also ok so long as you don’t use an AC supply.

  • the “74hc00” is a “74hc00 p”

  • the “bc547 b” is a “bc547 c”

perfect!

  • the “cny17- 2” is a cny17- 1"

Hmmm… the CNY17-II is the most crictial part of the MIDIbox Plus, some people noticed problems with the MIDI In and had to tweak the pull-up resistor. I’ve no experiences with the CNY17-I — it could cause problems. However, if MIDI-In doesn’t work, just switch to the 6N138 circuit which works much better.

  • the 8.7 v zener doide is a 8.2 v

should work. The 8.2V zener can also be found in the original schematic; most people are using this diode w/o problems.

Best Regards, Thorsten.
