Default Reducing phono output level of tuner?

Hi group,


I've just been given a nice Technics tuner, but it pumps out a very high
signal from its phono output - the amp only needs to be turned up to
about 10% for the volume to be too high. I know I'm going to be
listening to the CD player, with the amp at 25%, then switch over to the
tuner, and get blasted out of the room!


What is the best (actually simplest and cheapest) way to reduce the
output of the tuner? I'm OK about losing a tiny amount of quality if
necessary. I've had a look inside the tuner and there are no pots that
can be tweaked to reduce output.


Can you solder? If it were me I'd fit a set of resistors to act as a
potential divider and so reduce the level that way. Ideally at the amp
input. If you are willing to do this, it would help if we knew the o/p
impedance of the tuner and the i/p impedance of the amp.

Alternatively, I think there are some companies who sell such potential
dividers, pre-fitted into a small connector which you insert into the
leads. An example:

However for the same sort of price you can buy a cheap metal-cased
switchbox from someone like Maplin and fit resistors internally, or a pot.
This means you won't have to modify the actual tuner or amp, but requires
some soldering. The advantage is that you can fiddle about with the level
until happy with it.

Slainte,

Jim
