But I know that there is going to be a mismatch between the PC's
output and any input on the amplifier, as it is not designed to
accept such an input signal.

You shouldn't have any problems as long as you take it easy with the
volume control. In pre USB days this was the only practical way to
get audio from a PC to the hifi.

I'm currently feeding the output of a cheap and quite cheerful USB
audio dongle:

to a 70's JVC amplifier which has an input sensitivity of 150mV and
have not noted any mismatch or overload. More recent amps designed to
cope with the typical 2V output of CD players should have more
headroom.


The Amp. in question is a Goodmans Module 80, of the late 1970s! Works
fine, after I replaced some blown lamps, and some funny-looking bulging
capacitors, but cannot be described as 'more recent'! It is of the same
era as your JVC.
But I might still try it, I have a collection of old phono and jack
sockets from a much-loved but now dead cassette player, so I should be
able to make up the correct 3.5mm jack to 5-pin DIN connector required.
Your dongle (that sounds rude, but isn't meant to be!) looks good
value.
Thanks for help and ideas.
