Well I've pretty much figured out that this low mileage beast is way out
of alignment.
Of course I don't have a service manual, but I do have a scope and other
tools.
Bottom line, is their a quick and dirty way to align the slant blocks to
get them mechanically in the ballpark?
I have many DAT's that were recorded on known good machines that I can use
to play while I tweak.
I've played with the two alignment posts on the slant blocks till my
fingers are sore with no luck. I either get tons of digital noise, no
sound at all or a cyclic drop out, almost like a head is bad. No matter
what I tweak I can't get rid of the mistracking although I can get pretty
dammed close. Of course I am more than likely doing this all wrong but if
I had a test tape and a FSM I wouldn't be tinkering
Is their some rule of thumb that Tascam/Pioneer uses to get these things
in the ballpark? IOW start with them fully CCW, turn 5 times etc....
The one on the left (looking straight on through the door) is hidden by
the transport so I have to unload the tape to turn it, the one on right
can be adjusted on the fly.
Any ideas?
I just need to make this beast work for a couple of weeks and then it's
history. It has very low useage on the heads and with the exception of the
alignment is virtually brand new.
I appreciate any help!
