Do you not remember the old Makaswitch kits? Absolutely brilliant

to about six inches depth of wafers.

I do indeed remember them but not with any great fondness.

I remember having to be careful not to melt the wafers when soldering.

True, but that was easy; they were always very nicely tinned, and only
needed a touch of the iron.

Mostly I remember always removing the spring and detent ball mechanism
from one side to make them lighter to turn.

By the way, what is N-M-N?

A rather private Marky joke.. No More Nails .. Marky's preferred method
of fixing anything;))..

And it's spreading round usenet like wildfire! At least I don't get
the NMN jokes in a.b.p.e.senior-citizens!

As nothing is affordable on the open market, I'm planning on building
a switching box so that I can connect two 5.1 sources to the 5.1
analogue inputs on my amp. I was planning on using 3 double-pole
relays (BT47's) for switching the 6 channels. These would be
switchable by a front panel switch. Obviously, the unit would run
from a 12v power supply. How well would this work? Would the relays
cause sound quality issues? Any help would be appreciated.

I'm sure you can find yourself a six pole two way switch that will do
the job without all the bother of power supplies.

Really ? Ever tried it ?

Isn't that the old makaswitch system?..

Whatever you do avoid Lorlin switches...


That might do the job. A total of 18 wires will need to be soldered
to it plus finding the best way to fix all the braids together.

U could try N-M-N for that;))..

Anyway, this switch, plus enclosure, cable & connectors does work out
cheaper than the relay route. A smaller soldering iron would also be
handy.

Yup, I think that is the Makaswitch; I'm glad they are still around.

I'll buy it. It's pretty cheap, so if it don't work at least I
haven't lost much.
