Here the cabinet top has been removed to be refinished.
The top Jensen speakers have also been removed along with the mechanism
cover.
This is a photo of the crossover network, Two wires were cut and
twisted
together, the one in the foreground was not even connected.
This may have had something to do with the speakers possibly being out
of
phase when this was built.
But it doesn't explain why the right side was not connected at all.
Here the crossover, wiring repaired and speaker reconnected.
After a little more cleaning, it was returned to the enclosed area
accessed behind the amplifier and pre amp through a screwed in panel.
Note: You can see this area by removing the coin box and looking
through
that area.
woofer
Midrange speakers
Tweeter (highs)
These are the three types of original Jensen speakers used
The large woofer and tweeter are accessed through the panel behind the
amplifier and pre amp along with the crossover.
There is a bit of a trick to dismount the side speakers, one of the 4
brackets holding them slides into a groove in the cabinet.
This is the restored top
Here is a sample of the refreshed title strip holders with a new
addition. The backs of these were cleaned but not repainted, so the
original lettering and position stamp could be kept.
There is one change however, the title headings are custom. I purchased
replacements for the originals but I'm not using those plastic headings.
Instead I created new headings, using .019 aluminum coated in a
material that simulates anodized red. This is the same finish used on
the aluminum triangle grill pieces
(shown later).
The
lettering is raised vinyl. The background title coloring changes, like
the title cabinet
location bars, based on viewing location and lighting
The left photo shows the underside of this
dome trim in poor shape on the right are the parts that fell out
removing the trim on the left
UPDATE: Replacement rubber
U channel has been found to replace the original discolored, hardened
and broken rubber on the dome and title cabinet glass.
The dome and title glass used in this jukebox is 1/4" thick. The rubber
U
channel is 3/8" wide and high with a 1/4" interior channel for
the glass
The replacement material is slightly wider & higher but fits
perfectly.
Below left mounted on the glass dome edge
On the right, this cover damaged
when the neck was broken, now the metal straightened and Logo painted
with
faux anodized paint.
This an example of the condition of the buttons
before
After, all the
buttons cleaned (31)
This is the selector unit. Not shown here, 2 pins was removed
from one of the mating AMP-LOC connectors,
. A molex connector has been added here
(temporally).
Original AMP-LOC connectors and pins seem to have been lost to history.
UPDATE: I was able to get a few of the
AMP-LOC pins from Zuddie Smith and replace the missing pins for
select #14
As explained later all selector lights were out, turns
out they are in
series. One out, there all out. This done to drop the 25-26 volts.
This explains why they are not very bright, as the bulbs used are
6.3volt (around 4volts each in series)
Possibly 3.2 volt bulbs can be used, though their life would be
shortened and they have a shorter life span to start with. A dropping
resistor could be added
As with other components, shown here, dirt and cigarette damage has
been removed
I use a strong cleaner, Spray Nine, to remove that damage.
This is one of many crimp connectors
used by techs to make
quick solderless connections when replacing parts
These are pretty ugly and all need to
be removed. This process has
started
Update: I have been told by
a restorer that has done 50 of these
machines that is how the factory connected parts.
So, I have halted removing them, they still are ugly.
Here the title cabinet (radar) and turntable cover have had 60 years of
dirt and heavy smoking damage removed.
That cover looks pretty good here but there is some discoloration and
minor chips, it will be repainted
The foil label will be replaced.
Here the red anodized effect of these have been re-applied, one was
badly faded
Here the left door after damage repaired, texturing and repaint, not
shown the right door has also been done.
before
after
This is what the rear cabinet looks like at this stage. I noticed
there is one label upper right the needs to be replaced
All non- polarized cords have been replaced, with black non- polarized
cords, including the main power supply cord.
All interstage coupling caps were replaced with orange drop caps. All
the tubes were tested, all found with good emission.
All electrolytics were tested and exceeded the values called for.
I didn't mention
this before as each piece of the jukebox has been removed for testing,
cleaning, replating etc the hardware has been cleaned and
polished.
Below is an example of hardware used to mount the amplifier
There is one set of post combination missing, it was not there. It
turns
out the factory made an error installing the rails the amplifier mounts
to..
The rails were slightly out of alignment , so the complete set of 4
could not
be installed. This has been corrected and a original set has been found
and
installed.
The majority of the decorative metal has been sent out for
polishing a replating.
These were sent to Courtesy Metal
More detailed testing and repairs have been done at this stage
including the amplifier and
pre amp.
An intermittent condition developed, the machine would eject right
after placing a record on
platter.
All switches were cleaned tested and adjusted if needed, including
cam switches and connectors. NO (Normally Open)
contacts were tested to show no resistance,
NC contacts to show close to
zero ohms. After adjustments and cleaning the machine became more
reliable.
This machine has a feature that all of them don't have called
automix, a feature that allows extended play 7" 33 1/3 records to
be played.
The final operational test was to put a 7" small hole 33 1/3 record in
the rack and select it. It didn't work.
I was educated by restorer Zuddie Smith, that the platter and it's
spindle appear to be setup wrong .
On this Jukebox, the platter by default is set to play 33 1/3 small
hole records.
When a 45 rpm record is selected and placed on the platter it's
detected
by the jukebox and 2 things happen,
it changes the playing speed and also raises the 45 adapter in the
center.
Unfortunately. this jukebox did not do this. The 45 adapter was always
in the up
position, which is incorrect.
The reason for that turned out to be the addition of a washer and
large nut added under the 45 adapter to keep it up.
This was probably done because at sometime in the past, a nylon piece
was lost which is
part of the platter assy.
Without it, the center adapter would have stayed down permanently
not allowing the jukebox to play 45's at all.
With the change that was made, it could no longer play 33 1/3
records but could play 45's
This washer
and nut permanently elevated the 45 adapter
This is part of the reason the 45 rpm to 33 1/3
conversion didn't work.
Turned out it's actually, 33 1/3 conversion to 45 rpm speed
(automix) as mentioned before.
This seems backwards, from a design point of view, since 95 % of the
records were 45's that would be played.
Possibly the anticipation was that the mini lp's would take over the
market?
It was missing an extension piece (the replacement not show here)
which normally allows the 45
adapter to lift up.
With this arrangement it was always in large hole 45 rpm mode and could
only
play 45's.
(I had to fabricate the missing part mentioned above, if someone
reading
this has a spare original please contact me)
Finished! not powered waiting records and title strips
Here at night
This up close photo shows the aluminum title headings matched up
against the anodized record numbers and letters verticals
They are not paper.
Finally one more photo of the finished Continental 2 Jukebox
I will be posting some tips / info. as I move ahead on the
project. Such as things not covered in the manual or not clear in
the manual.
