Amplifier Switch Speaker Switch AMP SPK SELECTOR Aluminum Case Without Tube Amplifier Protection

Amplifier Switch Speaker Switch AMP SPK SELECTOR Aluminum Case Without Tube Amplifier Protection

Features:
- Larger terminals for wiring and larger shell
- Inner wire: single crystal copper silver-plated wire
- Function: With tube amplifier protection or without tube amp protection
- Shell material: pure aluminum wire drawing shell
- This switcher is a passive device, so there is no need to worry about sound staining. Selected parts are welded by hand using a soldering station
- Enable one in two out or two in one out. The ground wires of the left and right channels are completely separated
- Using 10A high current silver alloy contact switch, the contact resistance is ultra-low, which is comparable to silver alloy contact relay for Omron 30A. The switch can be upgraded to 25A (not included in the package)
- Laser lettering
- Soldering tin imported from Japan, first-class welding technology
- Pure copper gold-plated large terminals, excellent quality

Attention:
When used with two in one out (one tube and one transistor or two tubes), please note that the output of tube amp cannot be empty! ! Please select our version with tube amp protection. (Principle: A tube amp uses a transformer output. The transformer belongs to the inductance type and has freewheeling. The working tube amp suddenly loses its load and will generate 3~5 times the B+ voltage between the primary and the secondary, such as 300B single-ended operation If the voltage is 400V, the induced voltage is as high as 2000 volts, and it is likely to break down the output transformer. At present, most tube amps have protective measures. Please consult the equipment manufacturer for details. If you are not sure whether the tube amp is protected, for safety reasons please select our version with tube amp protection, or not turn on the two power amplifiers at the same time).
