Title: R651 value in a US Turbo Duo?
Post by: dee on April 25, 2021, 04:45:28 PM

Trying to repair a really nasty capacitor-rotted Turbo Duo. R651 is missing. Need the value to replace it, if anybody can find out. Please and thanks!

I've marked the location on the PCB of R651, if anyone can hit that with an OHM meter. Thanks, everyone!

Just took a picture with my phone.

Resistor shows 473. Then you look it up on this chart https://www.hobby-hour.com/electronics/3-digit-smd-resistors.php that says it is 47K Ohm.
