P. H. Hobbies

I got a P. H. Hobbies sound system in the 2-10-2 I got from Rex Ammerman. Paul Housey was the owner of the company. This board was made somewhere after the 19th week in 1990. P H Hobbies, Inc., 6861 T Dr. S. , Athens,   Michigan 49011 was founded in 1986.

Prices for their products ranged from $60 to $310 (old Walthers catalog)

 Right now I'm just documenting the wiring connections.

 

There is a connector right by the 4 diodes by the end of the board away from the IC's

calling pin 1 closest to the end of the board:

  1. motor input
  2. not used
  3. motor input
  4. battery +
  5. battery -
  6. not used

battery used was a nicad, 4 cell, 5.6v, probably works to 6 v

 

there is a 2 pin speaker connector on the other long side of the board, marked SPKR

there is another multi-pin connector in the middle of the same long side of the board as the speaker connector, calling pin 1 closest to the same end of the board (away from IC's)
