Hi head-fiers!
I plan to "batterize" my amp.. I'm relatively inexperient in DIY, I do own an iron (used it twice, destroying a perfectly good mouse in one of the times)
So I'm a bit afraid of messing with my amp.... I would train my soldering skills before opening such a toy, of course!
I'm wondering.. Can I improve the sound quality, using battery power? I 've been reading about batteries, and NiMH or acid-lead seem to do the job.. (is the internal resistance low enough?)
The plan is to put everything in a backpack. So, +-4 Kg (+-8lb) to get +-15v 2Ah is OK with me.. The absolute run time is not a big problem if it is something like 2-4 hours. (current consuption seems to be around 100mA)
About the charger-- (I dont mind to have only a tricle charger and let it charge during the night.) My question is: If I use the voltage regulator inside the ha1-mkII, can I avoid building a charger? Can I make something simple, like connecting a battery pack plus a switch to change in to charge and mains mode, somewhere inside the amp?? Or, If I use a regulated power source that i have lying around, can I add something simple as a resistor to make a trickle charger? Would the lead-acid batteries be better in this aspect? They are bettre in the internal resistance issue, right?
The amp uses +-15v, Can I use -+18v?? lead-acids seem to appear as multiples of 6v..
Hope my first post isn't too full of questions..
