Ameritron HF+6 1200W Solid State Amplifier 1.5-54 MHz . . . 1200 Watts PEP Output, Instant Automatic band switching, no tuning, no warm-up, SWR protected, Quiet Variable-Speed Cooling . . . PEP FWD/REF Metering...PA Balance /ALC Metering and LED Indicator . . . Front Panel Band/Error LEDs . .more! reliability is insured by using eight rugged MRF-150 power FETs. They are mounted on the dual heavy duty heat sink and properly arranged to spread out the heat over a large surface. This is something that other amplifiers using a single power device cannot do. Some FETs actually are a package of several transistors in one large case. This concentrates all of the heat in one small package. They not only are more difficult to cool, if one transistor fails, they all have to be replaced. AMP is fully up to date & tested at Ameritron, I have the receipt of verification. AOK Asking $2300.00 plus S/H.
