This is another 3055 with 3D sound USA Version. This case is in
Excellent shape. Nothing needs done with the wood finish. The
plastic parts were cleaned and treated with Glayzit. The Dial glass
cleaned and the red line on the FM indicator repainted.
Great
Cabinet.
The
FM dipole is forced into the SW/AM antenna jack. Rear wood frame a
bit fractured.
Record
speaker connections.
Remove,
protect and store the dial scale glass. It is made with "Unobtainium".
Glue
and clap split wood.
This
IF has a moving coil connected to the Treble control with a dial
cord.
The
moving coil is stuck.
There
is a deposit of something hard.
It
is functioning well after considerable work.
You
can see the dial cord that moves the IF plunger when the Treble control
is turned.
The
specified eye tube is an EM85. It is quite expensive and hard to
find. I could not find one that I trust to use.
I researched a substitute based on
performance specs. The EM81 tube is a fine sub. The pin
connections are different and the electrical specs are very close.
Seal
up all the alignment controls from slipping. You can see the green
candle wax and the old nail polish.
To
seal the trimmers use Glypt or something that cracks easily off for the
next alignment.
This tweeter is fine. Plays loud (for a Grundig). No repairs
needed.
This side speaker had some dirt creating a Buzzing/rattling. A bit
of dusting took care of that.
This
is an STSP toggle switch that is wired in series with the eye tube
plate. It is used to turn off or "blank" the eye
tube. Eye tubes only last for about 1000 hours then fade
out. Use of this blanking switch should extend the life of this
hard to get tube.
This
brass has a classic worn look. Some people would never modify the original
finishes of an antique (100 yrs old). That would lower the
value. And this finish is far from needing replaced. This radio
was manufactured in 1955 to 1956 time frame.
This side grill cloth can be easily replaced by removing the four grill
retaining screws.
The wood finish is in great shape. A rub down of Rejuvenating oil darkened
the tiny scratches and removed any old wax. The front grill looks
new. The New eye tube looks great too.
This is what it will look like when the lights are dim with a cool drink
in your hands! Happy Holidays.
The original Eye tube is an EM-85 (6DH7). This has been replaced by an
EM-81 that looks the same but with different pin outs. The specs of both
tubes closely compare. The EM85 is hard to get and very expensive tube, if
you can find one. Both popular vintage radio vendors that I do business
with do not carry it. And I do not want to risk the likely probability of
a re-marked or fake eBay purchase.
