RP17 and RP18 values
Automatic
RP17 2.7K
RP18 4.7K

this is for board pn: 02d01550-1500 Auto to Manual: remove rp17 remove rp18 add a jumper to rp18 Manual to Auto:

  • remove jumper at RP18 (Not sure what will be here)

  • add 4.7kOhm +/- 5% at RP18 SMD

  • add 2.7kOhm +/- 5% at RP17 SMD

  • add IC15 & IC16 5050 S0 or equiv.

  • add Caps at C73, c74, c75, c76 (values??? 0.1 uf ? should be ceramic)

  • add Diodes to D13 and D12 (1A Surface mount will work)

  • add q29 q28

  • add c57

  • Not sure about any transistors yet... If someone has a Manual P08 and can take a high quality picture of the top and bottom, Please email them to me.. CRXSi RVtec (mailto:[email protected])
