Dayton Audio 3 Way Tower Speaker project
During the summer I worked on project to build my first speaker system
from scratch. The project goes over some of the history and
results of the build. The final results are impressive for a first
time build, but now I have a better understanding of the difficulties
involved in designing a crossover and picking out drivers and putting it
all together.
Pioneer TX-900 SA-900
Older project were I rebuilt a Pioneerr TX-900 tuner that I
picked up off of Ebay. Also had updated the matching SA-900 Amplifier.
I just need to document some of what I did on that here. For more details on the
work with the TX-900 look for the link on the left side. Teac
A-4300SX - Dumpster Diving at its best
A few months back I went dumpster diving and found a gem of a Reel to reel.
At the time I was frequenting the local Salvation Army thrift stores looking for any
cool used gear. Most of the time it was a frugal attempt. But one
day, I took a load of used cloths to drop off when I noticed a something in a
cart covered with trash. Upon clearing the crap off of it was minty
looking Teac A-4300SX tape deck. It had a few dings in the wood panels,
but the face plate was in perfect condition, not a scratch on it Back at home I took it for a quick spin and found that the
pinch roller pivot arm had seized up along with some of the tension arms.
A little lubricant took care of that and now I have probably one of the best
performing tape decks ever. This coming from a guy with an Pioneer RT-701
deck that runs great and sounds great. The Teac just has a smoother
operating tape transport whereas the Pioneer is a bit more rough. Plus I
think the Teac is just an over all easier unit to work on, simple design
construction, and built very rugged.
Service Repair
I've actually had quite a few people contact me regarding issues with their M-91
amplifier. I'm flattered by inquires and do try responding when I have the
time. But by all means what worked for me may not work for you. Your
situation could be unique and going at your amp with a soldering iron in hand
with out knowing the potential dangers of working on electronics could be dangerous
to you and your gear. So please use good judgment before attempting work
on your own. You may cause more damage that will only make the service
tech smile when he bills you for twice the labor in fixing your oops. :) While
on this subject, I've had some people inquire about my services in repairing.
I've considered pursuing this as a side job, but I'm just a little hesitant to
take on some monstrous amplifier or BS'ing about my abilities. At this
point I'm working with one fella who feels comfortable sending me his Spec-4.
I know this is his baby, and him willing to trust me to work on his pride and
joy speaks volumes. So when and if this project gets off the ground, I'll
be posting the progress of it. Hopefully the feedback I receive will be
positive.
About
| Pioneer Elite has for years been one of my
favorite and most desired stereo components. However, as much as I
loved this equipment, I was never able to afford it when it was first
produced.
In 1987, I started working at a stereo retailer in West Central, IL.
This was one of my first part time jobs in High School. I must say this
was a hell of an experience. I learned a lot and had a great time
working there. During this time frame Pioneer began marketing there new
Elite components. I immediately loved the look, feel and build quality
of the components. The first pieces I saw were the previous 86' model
year A-88x and A-77x integrated Amps. By 1987 Pioneer was showing off
the release of there legendary M-90 and C-90 components, and oooh how I
wanted them. I still remember we played a Telarc CD of Star Trek and
literally blew the woofers out of a pair of brand new speakers we hooked
up to this mammoth amp. It ripped the rubber surround right off the
woofer cone. Ironically, these speakers were produced by NEC, and we
could never get replacement for the drivers. Nothing like a bunch of
sales people trashing a pair of $700 speakers within 10 minutes of
opening the box.
Anyway, the problem I had in purchasing this Elite equipment is, it's
kinda hard to save enough money at 3.35$ an hour to pay for it all. So
in the end, I decided to purchase the top end standard Pioneer
Integrated Amp and components. I still own these but currently
have them in storage until my son or daughter are old enough to
appreciate having them. Lets just say if they don't, then they'll
make a good down payment on a nice set of speakers. :-)
This consisted of the following
A-717 Integrated Amp, 100W per channel
F-717 AM/FM Tuner
PD-7100 Single CD player
CTS-800 Single 3 head Cassette Deck
DSS-7 Pioneer 3 way Speakers
