You need the resistors to ensure that the voltage is distributed evenly across the 2 caps.

oops yes of course, Capacitance in series will be divided;
thanks for the explanation about the resistors.

I use the Atoms from Mouser as well. I've used newer/smaller capacitors... but the Atoms are my preference. Go to Mouser and look for the Vishay/Sprague "TVA" capacitors, such as 75-TVA1906.

ok, I think I go with the series caps.
For the few times the amp gets used....
one more question. is 1/4 watt sufficient for the resistors ?

What was that I said earlier about taking the time to study the basics? :razz:

Use Ohm's Law.

The power dissipated in each resistor is:

P = Vsq / R

Where P is power in watts, Vsq is the voltage the resistor (squared) and R is the resistance in Ohms.

Then pick a resistor rated for at least twice that wattage.
