I do believe you can substitute a mrf 455.

Try the Quakshack.com, look under non ham linear amplifiers, There is a thread about the eagle 515 the pcb is the same as the 500. there are some great close ups of the pcb.There is also a video of the pcb on you tube just search for eagle 500. I just completed a rebuild of an eagle 500 if the...

Had a great deal of success today, I was using the amp with the covers removed, replacing the covers did help some what but i was still getting a little distortion and a slight squeal. I have been running on as low a wattage as i can make my galaxy run with the mic gain all the way down...

Well I have changed all the diodes,capacitors, transistors, and re soldered all grounds, and have had no change. I am starting to believe that the galaxy rig i am driving it with is a little more than it can handle on the ssb side, or there is a problem with 1 of the tubes, although i am getting...

I have tried all of the above except the ground re soldering, There are a few places along the grid there are ground lugs. I have inspected the foil side of all the boards for cold joints and havent found any thing yet I get the feedback in upper and lower side with mike gain and power turned as...

I have been rebuilding an eagle 500 That is in fairly nice condition, all original with original tubes. I have replaced 80% of the capacitors the only ones left are the silver mica caps in the final drive section. I have replaced the transistors for the preamp and ssb circuit but i still am...

The latest project is an Eagle 500 in very good condition with no mods done to it, I am looking for a good part number for the rectifier diodes, The schematic calls for a 1cc170. There is no such animal as far as i can find. anyone know what a good part number for this diode would be.
