Electrix Repeater with mods

Audio Proz Inv #: 33153

with modifications, modest used time; see here for details.

Please note: only specific and slightly rare "CFC" memory cards can be used with the Repeater. The power supply is also rare, and at times only an expensive "industrial grade" power adapter ($100+) may still be available. Because of this, getting a whole package together can be expensive. The modification, CFC card, and power supply might total $300+.
