The relays will be a heck of a lot cheaper !

Even considering power supplies etc?

I'd use a spare wall wart left over from some old kit that was chucked out. They come in handy
like that. Plus I'm no fan of clunky rotary switches.

Do you not remember the old Makaswitch kits? Absolutely brilliant things
- you could put together exactly what you needed with them up to about
six inches depth of wafers.

As nothing is affordable on the open market, I'm planning on building

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 ?

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

If you are using a small metal box, then try simply using stiff wires for
the signals, and just ensure the box is connected to the socket outers. May
not need to use coax internally.

Isn't that the old makaswitch system?..

Whatever you do avoid Lorlin switches...

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

Are they no longer available? Sad given how useful they were.

They *do* look like the Makaswitches of old. I used many of them in the late
60s when building Mullard 5-10s and 2 valve pre-amps. Also on a Brenell tape
deck. Very useful and reliable.

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

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

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