BASIC HINTS ON THE CARE OF
GRAMOPHONES
1. Keep the machine as
original
as possible. Originality adds value.
2. The box or cabinet
- Early horn gramophones
usually had
oak boxes.
- Retain the original
French
polish on
early models if possible.
- Never use lacquer,
varnish,
etc. on
early gramophone boxes - French polish only.
- Preserve the transfer
(decal)
on box
at ALL COSTS.
- Later cabinets
gramophones
were often
made of mahogany or oak, and used a cellulose lacquer finish.
- Only re-polish gramophone
cabinets
if very badly damaged.
- Never use silicone
polishes.
Use microcrystalline
wax only.
- Retain original grille
cloth
where
possible, even if it is damaged.
- If grille cloth has to be
replaced
avoid modern bright-coloured shiny cloth.
3. Metal parts
- Nickel plating can be
cleaned
with
tarnish removers or brass polish or fine steel wool. Avoid using
buffing
wheels.
- Polish with Duraglit type
pads (never
use polish solutions containing abrasive powders).
- If parts are rusted,
pre-1930
models
can be re-nickel plated (never chrome plated).
- Later models were chrome
plated.
4. Horn
- Preserve original paint
at
ALL COSTS,
even if there is some damage.
- Horns with original paint
are
rare
and worth preserving.
- Repainting horn with
lacquer
spray
can be better than using enamel.
5. Motor
- Oil motor regularly - you
cannot over
oil.
- If motor 'thumps' when
playing - the
spring case need greasing inside with graphite grease.
- Never work on a motor
unless
it is
fully unwound.
- A spring may break at any
time. Springs
can be repaired.
6. Sound box (pick-up)
- Pre 1925 sound boxes had
mica
diaphragms.
- After 1925 aluminium
diaphragms were
common.
- Treat all diaphragms with
great care.
- If records are distorted
(with buzzing
sound on loud notes), rubber ring gaskets in sound box need replacing.
Seek advice.
7. Needles
- Gramophone needles are
designed to
play ONE RECORD ONLY.
- Throw away needles after
one
playing.
- NEVER put a used needle
back
in soundbox.
- Use softer tone needles
on
records
made after 1930.
- Avoid loud tone needles
where
possible.
Loud needles wear records.
- Avoid needles that
supposedly
play
ten or more records - they are for early electric pick-ups.
- Avoid coloured needles
(bronze, gold,
painted. etc.) - they are for early electric pick-ups.
8. Records
- Most gramophone records
should play
at 78 rpm.
- Run off grooves occur on
records after
mid 1920's.
- Run in grooves occur on
records after
the mid 1930's.
- Records after 1945 should
never be
played on wind-up gramophones.
- Records can be washed.
(Use
warm water
and detergent and new shoe brush; rinse and dry between newspaper.)
