Can anyone tell whether this switch might be faulty:

It's the input selector switch, and the amplifier can only switch
between two of the four sources.

Thanks, Rob


If the amplifier can only select two of the four sources, then, unless
the wiring is at fault, almost by definition it must be the switch. If
you look at the switch photo, there is no wear on two of the contacts,
indicating that the switch is not making contact. However, the switch
looks like it is a six-way switch, and you say there are four inputs, so
perhaps it is being mechanically stopped and therefore there's no wear
as the contacts have never been used.

My conclusion therefore is that it's not obvious from the photos whether
the switch is faulty. As you have gone this far in removing the switch,
I suggest you just replace it.

Many thanks - apparently the input switch is a weak point on these
amplifiers, and this is not the first time it's been replaced. It's just
that it doesn't *look* broken (no me!).

Can you tell from the photo how many poles it has? There aren't any
model markings on the case, and the only source I've found is:

(Lorin switches, half way down the page).

Thanks, Rob

What you really need is two pole four way. They have used a two pole
six way, and disabled two of the ways.

The Lorin 2P/6W version half way down the page looks OK. Choose on the
basis of what looks like it will fit best, though.




You could fit something -better- they've never been all that good in
quality....
