Hi guys,
my current portable setup runs like
Nomad JB --> TA ---> Beyerdynamic DT 770 (250)
i wanna get a bit more omphh into the system as the TA on 2 AA's loses a bit of the low end etc. i've tried running at 5V and it does sound quite a bit better.
I was thinking of using a 12V SLA to powr the whole lot but not sure how to get the 2 sets of rails i would need.
unless the the TA can take a higher voltage i would be looking at +/- 5V and +/- 12V.
could some one help me with the design of the voltage regulator setup ??
easily avaliable reg's are
7805/LM340T5 - +5V
7905/LM320T5 - -5V
7812/LM340T12 - +12V
7912/LM320T12 - -12V
their all fixed voltage and 1 Amp.
how would i wire this up ? would it create much heat ? ( it needs to go inside a carry bag )
any other ideas
btw i looked at multiple D cells but would rather an SLA.
