"Please note, several year ago, this SID Station had a repair to replace a voltage regulator, which was performed by Syntronics Audio. As a result of the replacement part that was available, a slightly different external power supply needs to be used. A 7.5v power supply is required. I'm including a switchable power supply that works perfectly. I've had zero issues with the SID Station in the years following the repair!"

"Extremely rare and hard to find original poster

Measures 24 by 36

There is some damage to the sides as shown in the pics but once framed you can’t see it. I’ve had this framed for many years and have recently changed out with another poster. Very hard to find original poster"

AlfaVox System A1905 - Modular/Analog Synthesizer (Made in Sweden - 2005)

video upload by Stephano Gavilanes

You can find pics of the AlfaVox in this previous post.

"First encounter (no effects), with the AlfaVox System A1905 synthesizer, only one unit was made.

It is not a 5U, neither a Serge panel, nor an EMS synth, but it is very capable to tap into those sonic palettes.

Enjoy it!"
