REPLACEMENT TURNTABLE
CORKS FOR SCULLY 280 TAPE RECORDERS
We have also contracted
with a supplier to make replacement turntable pads for the Scully 280-series
recorders. These fit both 280 and 280B recorders.
The Scully 280 corks are $6
each ($12 per set), plus sales tax (Washington state residents only), plus
postage. These pads are similar to the Ampex corks shown below but are thinner
and do not have fabric backing. Minor adjustment of turntable height may be required after
installing the new corks.
REPLACEMENT TURNTABLE
CORKS FOR AMPEX TAPE RECORDERS
We have contracted with a
supplier to make replacement turntable pads for Ampex tape recorders. The pads
are $6 each ($12 per set), plus sales tax (Washington state residents
only), plus postage. These pads are manufactured to original specifications and
made from 1/16-inch cork/Buna-N (nitrile) and include a thin fabric backing as
used on the original pads.
To order, contact
Full-Track Productions by phone (206) 784-6963, or send e-mail to Dave at the
address listed on the home page. Overseas shipping available. Payment may be
made in cash, postal money order, or Paypal (e-mail for details).
For additional
information about replacement parts for Ampex recorders, see http://recordist.com/ampex/docs/parts/ampexpts.html.
There are two pad styles
available:
Type 1 has a 5/8-inch
center hole and fits Ampex 300/350/351/354
Type 2 has a 1-inch center hole and fits Ampex AG-350 and AG-440

ORDERING
Measure the inner
diameter of the existing turntable pads, if they are still in place. Keep in
mind that some older machines were retrofitted with replacement AG-350 motors
(or vice versa). Also, Ampex sold an upgrade kit to allow end users to repair
their older motors if the steel pins pressed into the turntable surface near
the center spindle became damaged.* So your machine may need a Type 1 or a Type
2 pad, depending.
Check your machine
carefully. Each reel motor may require a different pad.
If you are unsure,
examine each reel motor turntable carefully. Near the spindle, there will be three
little steel pins (or stubs of these pins if they were broken off) or a small
casting with three fins. If the turntable has the
fin-type centers, you should order the Type 2 (AG-350/AG-440) corks, regardless
of the age of the motor or the model number of the recorder.
Your reel turntable(s)
may have been retrofitted with a drive pin for 7-inch plastic reels. These
drive pins were typically inserted in one of the three outer holes in the
turntable (the three outer holes in the replacement corks line up with these
holes). Since both replacement corks have these three holes, both are
compatible with this type of retrofitted drive pin. Simply order the type of
pad you need based on the inner diameter required (as explained above), not
whether there is an outer drive pin or not.
ADHESIVES
These turntable pads are
sold without adhesive. This ensures both a long shelf life and long service
life (pressure-sensitive adhesives lose their effectiveness over time).
The most secure adhesive
is a spray adhesive such as 3M type 77. I have found it sufficient to coat only
the pad, not the motor turntable. Your mileage may vary. Either way, be
sure to clean the reel turntable before applying adhesive. You may need to use
a stout putty knife and careful application of heat to soften the old adhesive.
You may use a
nitrile-rubber adhesive such as Pliobond or other equivalent. Squeeze some out
of the tube on a clean surface, mix a bit, then spread onto the gasket and reel
turntable with a flat plastic putty knife or stick. Keep in mind that this type
of glue has a a short shelf life (if both liquid and solid components squeeze
from the tube, discard the adhesive).
