splus mother board blows the R3 resistor/help needed please

(1/4) > >>

slotdoofus:
I'm working on an Splus machine. The machine has a couple issues. I'm not sure if they are related.
First off, I noticed the Q4 transistor was burnt on the CPU board. Along with this...the R3 resistor on the motherboard is also burnt to a crisp. Can someone provide some assistance?

Stayouttadabunker:
You neglected to tell us if that's a 10 or 16 Mhz board...I will assume that's a 10Mhz board.

On the motherboard, swap the R4 resistor (oops...R3....sorry! )with a new orange, white gold, gold resistor and you should be back in business.
I attached a resistor colorchart below for you!

The Q4 triac is a L201E3...not available at mouser.com...but here's a link to a sheet on it.
You have to look around for 'em...>>>

slotdoofus:
But what about the burnt R3 resistor?

Stayouttadabunker:
Typo...meant to say the R3 resistor on the MB.

slotdoofus:
I found the L201E3 transistor, (original 201 is discontinued...replaced w/ a 401).
