I bought a used Nakamichi TA-4A Stasis receiver and I am currently
using it in a spare room to amplify a DVD
player.

I have a 13 year old son who never turns things off. And by "never"
I
mean NEVER EVER.

Every time he uses the receiver to watch a DVD, he simply walks away
from it when he is finished.

Today I came home from work and found it on. He had used it that
morning, so I estimate that this amplifier had been on for about _8_
solid hours when I came home and discovered it.

Is this bad for it? It has good ventilation all round it, but it was
quite warm from being on so long.

Should I ban him from using the receiver, or am I being needlessly
picky?

This is an interesting issue. For a quick answer, I suggest you just
tell your son to turn it off or else. Deduct his allowance or
something. He needs to learn why leaving it powered on may not be a
good thing. Once he learns that, let him do what he wants.

For the longer answer, let me start by saying that I leave my amp on
all the time. I do it for 3 reasons:

1. I don't want to wear out any power components over time by the
constant powering up and down of the system. I do the same with my
computer, leave it powered on and configure it to sleep and I only
power off the monitor, the biggest consumer of electrical power in
most computer systems.
2. I know that my amp, a Yamaha AX-596, is a class A-B system which
draws insignificant amounts of power when it is powered on and doing
nothing.
3. The record-out selector on the AX-596, enabling the Computer to
record FM radio etc, does not function when the amp is powered off.

Now , if I owned a class A amp, the type of amp that draws
considerable amounts of power even when idle, I would plug it into a
power strip and power off the power strip when not in use.

****ing any power away unnecessarily is an insult to those who don't
have it....

Yes it is, but we're talking miniscule amounts We're ****ing atoms.
Here in the US, soccer moms drive around giant SUVs usually at 10%
capacity. These SUVs have AWD which is almost never used, yet it is
always being paid for thru drivetrain losses and poor gas mileage.
Computer datacenters consume HUGE amounts of power to keep things
frigid and the servers inside normally run at 20% for most of their
lifetime. Yet, regarding leaving the power on of an amplifier gets
this rebuff?
Come on now. That's why I encouraged the OP to make his son realize
that it is wasteful, just not so much.

if everyone in the USA turned off their stereo right now, how much
would that save?
If every soccer mom traded in the SUV for a more fuel efficient,
perhaps FWD vehcle, how much would that save?
If every datacenter found a way to more efficiently use their
resources, how much would that save?

Let's keep things in perspective.
