Sorry to dig up an old thread... but I'm thinking of attempting this just for shots and goggles. Ive had this amp around for awhile and i'm ready for a new one. But perhaps i'll go and ruin this one first :D .
Just a question or 2 if anyone wants to enlighten me. Would these particular caps be safe for home use with the 12v dc input? Or would i rather select something like the 1000 uF 10v? The OP makes it sound like those 6.3v are pushing their limits even using a 9v battery. So do i need something different if I'm using the 12v plug? I'm obviously new at this but if someone wants to point me in the right direction for perhaps a sound improvement of "some sort". Or if you want to explain to me why it's not worth the trouble I'm all ears as well. Laymens type explanations are best for us noobs :) . But unlike the op almost seems to suggest I dont think this is brain surgery either and im not sufficiently discouraged to just "stay out of the pool". So take that as you will.
Anyway atm im thinking why not just give it go. I got a friend with a solder sucker and all that solder stuffs. This is a decent amp and all BUT I do agree with most of the gripes the op mentions and I wouldn't mind to try tinkering with it before I just buy a new one. I'm going to be using it with ZMF's and other full size headphones in the future.
Is this really the sort of thing that yields "night and day" improvement?
Also the AD8397 opamp.. Anything better i should look at these days to swap that out?
Remember im ready to try something new anyway. So why not tinker.
Thanks for listening. Input is appreciated.
