5C1 Power Resistors

[dtjacob]

The parts list I have specifies 2-500ohm 10watt power resistors........can 5 watt resistors be SAFELY used????? Those 10 watt resistors are HUGE!!!!!

Thanks.

5W will be fine for both resistors. Likely voltage drop accross both will be in the region of 20-30vdc @ <60mA, allowing for relatively high B+, therefore 30v*30v= 900. 900/500ohms = 1.8W dissipation.
