The Firebird F-500 10-12 Meter Linear Amplifier is a high-quality amplifier designed for ham radio enthusiasts. With support for SSB and AM modes, this black amplifier has one input and one output, making it a versatile option for those in the HF band. The Firebird F-500 is a reliable and efficient amplifier that can enhance your radio communication experience. The power switch is wired on. I use a power strip for the on/off function. All other switches work as they should. The neon power light works when it wants to. Does not affect operation of amp. I use this amp on both the 10 and 12 meter bands and it works good. 6LQ6 tubes. 250-300 watts output with 1 watt dead key. See video...Not for use on the 11 meter CB band! It is labeled on the back...Thanks for looking!
