SOLVED Magnetron resistor (substitution?) question

[jhalton]

Hi folks,

I am putting together a Magnetron, and I am one 4K7 resistor short. I'd prefer not to wait until my next Tayda order, so I am wondering if I can substitute one of them. I have ZERO electronics theory, so I am not sure if this is ok.
I'll attach the PCB and schematic.
Thanks!

ps. first post (probably of many!)

if you have x2 10K resistors you can stack them in parallel for an equivalent 5K resistance, which will be a close enough substitution for 4.7K

102 or 103 don't have to be 4k7. They set the brightness of each LED. If you're using a blue LED you'd want to go a higher value resistor here, like 6k8. It's really not that crucial though. The only important thing about LED resistors is it can't be lower than like 390 ohms in this circuit at 9v. Anything higher than that just adjusts the brightness, so just use something close
