Re: Two filaments on a battery: bad luck?

Hi ,
Remember the dropper can be incorporated into the bias network ;) I used a DN2540 set to 20mA to charge the batteries in my linestage . I don't know if this is the best way to do it but it works and the batteries never get hot during charge . Whatever form of indicator you use will drain the batteries , maybe the best idea is to buy an LCD voltmeter module and build this into your project
