Anyone has schem or links for an easy to built motorizied volume remote
control ?
I've found Alps motor pot but no schem to use it.

Regards

Check the google record for discussions on remote volumes controls.

Mikkel Simmosen has some goodies for you :-)

Hi -
I've got a bunch (surplus store), but they're mounted on a PC board & are
50Kx2+ position pot (a stack of 3), so they're SS type of a deal... OTOH,
the PC boards (ugh) are really small, and are not only populated, but are
clearly marked, using 5V as drive voltage. The things use a reduction
drive, at ~ 1RPM, so you just apply the voltage (ground & up or down pins) &
the knob slowly turns - no exotic circuitry needed (unless you wish to use
indicator bars - useless, since there's a knob showing you your vol.
setting).
the whole contraption looks silly in a toob amp, and even though i have
one on my Maranz power amp in the "family indestructible system", it never
gets used - while it's neat to watch the knob move, that's about it. Try a
"mute" switch instead - i have mine set up to *almost* mute the system.
Much simpler & looks fine in a tube amp.
OTOH, if you're into the poooorist attenuator switches, I have 12 Alps
(relabeled, but they're Alps) 14 position (if I remember right) attenuators,
479K to 0, wired in audio progression through WW 1% resistors (these were
cut out of a rack of ECG (medical) amps, and the resistors are
turret-mounted on a chunk of PC board. These are miniature & stackable
(each one's mono, but you can stack them a mile long. (I've got a 24 pos
full-sized alps with 12 switches on the same shaft + a push/ground switch to
avoid pops while you're switching).Tell me if you're interested in swaps - I
need a pair of decent 5 to 7K -8Ohms *matching* SE iron (used & short leads
OK), or decent PP UL or cath. feedback 8K to 18K - 8Ohm, reply if
interested, & I can send you pics & my email. Also have tons of other crap
(err... treasures) to swap.
