Keeping dew off secondary - How much power?
Hi Folks,
Just after a little advice as to how much wattage at 12v would I need to keep a 2.5" secondary dew free and just above ambient?
I would just like to make a resistor based warmer to go behind the secondary and would like to know what works for you?
Would 1/2 watt be too much and cause thermal problems etc?
cheers Gary
