Up for sale is a classic Realistic Stereo High Power Remote Speaker Switch, Catalog No. 40-135, made in Japan for Radio Shack (Tandy Corp.). This rugged passive speaker selector lets you connect one stereo amplifier or receiver to up to four separate pairs of speakers and easily switch between them.
Great for whole-house audio, multi-room setups, indoor/outdoor speakers, or expanding your vintage hi-fi system.
Key Features:
• Four independent front-panel toggle switches (Speaker 1, 2, 3, 4) – turn each pair on or off individually
• Heavy-duty push-button spring-loaded binding posts on the rear for secure connections (accepts bare wire up to 12–14 gauge)
• One stereo amplifier input (Left & Right channels) feeding four speaker output zones
• Labeled clearly: “SPEAKER 1 IN/OUT”, “SPEAKER 2 IN/OUT”, etc.
• Built as a “High Power” model for use with stronger amplifiers common in the 1980s–90s
Condition:
• Good vintage condition with normal signs of age and use (scuffs, scratches, and light wear on the black metal case and wood-grain top)
• Some adhesive residue and old tape on top with handwritten zone labels (can be easily removed)
• All four toggle switches move freely and click positively
• Binding posts are clean and functional
• No major dents, cracks, or broken parts
Important Notes:
• This is a passive device – no power cord required
• Like most speaker selectors, use caution when running multiple pairs simultaneously. Check your amplifier’s minimum impedance rating (typically safest with only 1–2 pairs on at once unless your amp is 4-ohm stable)
• Compact size fits easily on a shelf or in a rack
Specifications:
• Cat. No. 40-135
• 1 stereo input pair (AMP L/R)
• 4 stereo output pairs (Speakers 1–4)
• Made in Japan for Radio Shack
This unit pairs perfectly with other vintage speaker selectors like the Adcom GFS-1 or modern ones like the Monoprice 4-channel for a complete multi-zone audio setup.
Shipping: Carefully packed to protect the switches and binding posts. Ships from Denver, CO.
