Re: Heaters from mains
I have been thinking on use an ECC83 for oscillator-amplifier and an ECC82 for power output. The total amount of power output required will be less than 1W, I think the two sections of an ECC82 can do the job if paralleled.
Then, with the heaters of the ECC83 and the ECC82 in series, I need only 150mA, and for that I would need 1,6uF only (+/-). I will look for the higher voltage rated capacitor in my stock.
