OK..yes with no volume control on the vcr circuit itself, but i have a
set of powered speakers that have volume/power on them...so what i was
going to do is say wire the vcr circuits channel up/down for the
volume control. It's sounds half assed, but if i can get the vcr
circuitboard to light/power up so i can use the IR functions on it,
i'm sure i can wire the whole shebang into the speaker amp and have
the vcr boards channel up/down as a suitable volume up/down. Thats the
problem i'm originally having, powering up the vcr circuitboard so i
can use the IR functions on it (and possibly the lcd display).
I can't find any schematics on that vcr anywhere, and need to know how
the board is powered (there are 3 sets of wires coming off the board a
13 wire group, a 9 wire group and a 8 wire group..and the circuit
traces on the 13 wire group head towards the IC 751).
The way i have my home entertainment set up is the powered speakers
are hooked up to other speakers are hooked up to the Sat receiver for
stereo sound, what i wanted to do is use a IR, build a suitable box
and connect all the speakers with RCA plugs, then use my existing RCA
remote (TV and Sat are RCA as well) to turn on/off the whole speaker
system and change the volume levels, instead of getting up and going
to the main speaker which has the volume control on it (they are
Syntony MS 405 160w computer speakers).
