On

occasion,

however,

you

might

to

make

your

own

setting.

This

is

advisable

in

a

variety

of

cases

--you

might

be

using

an

older

record

that

was

not

recorded

at

a

stabi-

lized

speed;

you

may

wish

to

provide

your

own

accompani-

ment

to

the

record,

which

might

entail

changing

the

disc

speed

to

conform

to

your

own

speed,

or

you

simply

might

want

to

listen

to

the

record

at

some

speed

other

than

at

what

it

was

recorded.

To

do

this

simply

is

also

marked

with

Ef)

Each

cartridge

has

a

specified

load

capacitance

into

which

it

performs

best.

To

determine

the

capacitive

load

on

the

cartridge,

the

capacitance

of

the

receiver's

phono

input

cir-

cuitry

and

the

capacitance

of

the

turntable's

tonearm

and

output

cord

must

be

added.

Often,

this

amount

is

less

than

that

required

by

the

cartridge.

The

capacitance

trim

fea-

ture

allows

you

to

add

100pE

or

200pF

to

the

normal

amount,

so

that

nearly

all

cartridges

can

be

accommodated.
