I am trying to finalize some part numbers for the PPA and battery board and have some questions i haven't been able to find an answer to

1) For those of you who used the CRD with the ZNR diode, what part number did you order for the CRD and from where?

2) I have my battery board with 18 AAA cells and have the following resistor values (using LM1086)

R1 - 1*K?
R2 - 2*?
R4 - 120*K?
R5 - 8.2*K?

what values should I use for R3, R5, R6, R7 and R8.....

i'd like to make amp temperature based but i don't have a clue as to what part number the thermistor i would need for R7 would be

anyone know?


what R4 is a good value for use with Grados?


thanks,

Sorry, can't help you there. I have some info I need to investigate still, but I'm not going to pass it on until I've tried it myself.

Same as R3, maybe as much as twice as high.

if i was to make it time based i put in the values into the calculator and it said it couldn't calculate the R6, R7 and R8 values when i used the calculator


i put in 650 mAh and 1 hour charge and 18 cells and i used the second option on the chart for R1, R2, R4 and R5

but the other R values weren't given


what should i use?

thanks for the help, btw
