Title: PC Engine GT, need a resistor network value
Post by: Slypty on March 25, 2017, 12:36:42 PM

If anyone happens to have an opened GT or TE, I received one missing a resistor network from Japan and need the values of the packet/network.

  Me thinks the vendor ripped it out by accident and put it up for parts, even though the caps havent been touched yet.

  The resistor network is located near the R200.  You can see it in the link below, above the ribbon cable, and just to the right of the capacitor at the end of the ribbon cable.  It'd be a big help in knowing if there's a part number or any resistor values in that location, many thank yous

I've got one here and each resistor in both R201 and R202 are marked 562

It's the resistor packet value on R200 I need.. the R201 and R202 are completely different packets.. it should have a chip number with a few embedded resistors at R200.. Thanks

Oops, I shifted the numbers up in that reply.  R200 and R201 are 562

It's a 5.6K resistor array 1206.

Thanks a GT!  Very helpful
