firstly, the MRF455 fitted to the later, 'high-power' Lincoln, actually shows less overall power than the MRF477 variant. neither would threaten the B300p unless running flat out, and then it's more of a danger to itself than the amp. fit a computer fan to the top, ensure a clean power supply around the 20amp mark, and enjoy the megalomania! In the RF Limited FX75-150 previously they used that same circuit with mrf 455's they had them with a single and a dual MRF455 well a single at the very least and it was called the DX100 Kit. I know I bought one in 1991 or 1992 in High School for my RCI 2950 because the RCI 2970 did not have feed back circuit yet and they had stability issues. MRF455 By MA COM. RF Power Transistor NPN.

In the push-pull circuit configuration it is preferred that the transistors are used as matched pairs to obtain optimum performance. The matching procedure used by MACOM consists of measuring hFE at the data sheet conditions and color coding the device to predetermined hFE ranges within the normal hFE limits.

An HFE(gain) test at dc doesn't, and very rarely reflects its gain at RF. @Zephyr; Maybe your multimeter was £59 back then, but that means nothing. On this note, my Father once bought an Acorn Electron 32K memory pc circa 1985 for about £200, and looking back, it was a junker.

I picked up this amplifier because I was looking for a small amp to run on the base for a couple of months when I was running a temporary setup and I had to limit my output power at the time. The Silver Eagle 200 is a very simple and compact little amplifier.
