With the best warranty in the business and the best-equipped shop in the world, it's easy to see why
we are the "King of 8 Track Repair".  This is just one of our many Vintage Audio repair benches
where your prized item will receive our renowned top-notch attention and full restoration of all
features to their original factory specifications.  Below, you will be introduced to a few pieces of
test equipment that set BARRY'S 8 TRACK REPAIR head and shoulders above the rest.

At BARRY FONE MUSIC, we've been working on this stuff since it was new, and have improved and
refined our methods to continue delivering top-notch work as the units age and further deteriorate.
In addition, we have the specialized test gear other shops don't have, which means we can find
potential future problems that they can't.  The result is amazing repair quality which is GUARANTEED
to give complete satisfaction for the remaining life of the unit.  See a few of our more specialized
pieces of test equipment on this page, as well as our massive service manual collection.
For meticulously precise head adjustment on a quad machine, a 4 channel scope is the only way
to go.  This enables us the observe audio levels on all 4 channels simultaneously, without
depending on our ears which can become fatigued and inaccurate after repeated listening (much
like the nose gets tired after sampling several brands of cologne).  The fact that channels 1 and 4
are typically weak (being on the edges of the playback head) makes it even more important to
have a visual reference.  You won't see a quad scope in any other 8 track shop!
We spared no expense when it
came to offering superior service
on your Vintage Audio equipment.
This Sencore SG165 analyzer
generates all necessary signals
to tune up your receiver perfectly.

In addition to providing extremely
accurate AM-FM carriers with
audio modulation, this fine gem
also provides direct reading of
power output on left and right
stereo channels.  The Sencore
SG165 has been the industry
standard for decades - that is,
for shops who go the extra mile!
Typically found only in laboratories due to their expense,
The HP 331 Distortion Analyzer is another item you won't
find in the average repair shop.  Factory spec for the best
audio gear is on the order of 1 or 2% distortion; this piece
of gear can measure it down to about a tenth of a percent.
As 8 track tapes in particular possess a fairly large amount
of distortion, this is a necessary piece of equipment to have
around, and we use it extensively.  Below it is the HP 214A
Pulse Generator, which is used to calibrate our own scopes.
Here is something I can guarantee you'll never
see in any other repair shop, because they are used
primarily in design labs.  It is a Curve Tracer, and
is used to precisely match two (or more) transistors
of the same number and type.  Even between two
identical transistors, they will have slightly different
electrical characteristics, which means your left
channel may sound different than the right, or
have slightly more or less output power.

For the most discriminating audiophile, a shop which
has a curve tracer at its disposal will provide much
more satisfactory service than any other at any price.
My massive book collection covers everything in Electronics from simple audio circuits, right up
to Avionics (my day job), Radar, Spacecraft Technology and even a little Rocket Science!  These are
all ELECTRONICS books; my personal book collection is on another wall.  On the two bottom left
shelves is the COMPLETE set of Sam's Tape Recorder Series service manuals which contain
schematics, parts lists and board layouts for just about every 8 track machine ever manufactured.
To prevent too much clutter, here are just a few of my original manufacturers' service manuals,
along with Punky, the official shop cat.  Punky stands guard over the manuals and handles the
tougher repair jobs that I can't figure out.  As a special treat to my customers, she is shown nude
without her cute little BARRY FONE MUSIC uniform and tool belt.   Not exactly camera-shy, is she?
As mentioned before, I am an Avionics Technician by day.  I work on equipment used in airplane
cockpits, which as you may know CANNOT fail in operation!  Cruising at 50,000 feet is a bad time
for my repair work not to hold up, and I haven't killed anyone yet.  The antenna amplifiers I repair
mount of the underside of planes and see temperatures of minus 40 degrees at altitude, not to mention
greatly reduced atmospheric pressure which can wreak havoc on sensitive devices.  The quality
of my repairs and the discipline of my ethics enable me to give you the best job you will ever find
You won't find
many shops
who use test
equipment once
owned and
calibrated by
NASA!
