  •  3-500Z  TUBE

    3-500Z TUBE

    This is a used Eimac 3-500Z. I recently tested this 3-500Z in my linear amplifier. When I  paralleled it and a full output 3-500z, the pair delivered about 50 watts less than a pair of full output 3-500Zs as measured by my MFJ-870 watt meter into a 50 ohm dummy load. This was my spare.  The metal shield on the inside the tube at the bottom has LNS026 inscribed in it. The outside of the glass envelope has the numbers 08594  9511 printed on it.  It is sold AS IS with no right of return and shipped only to the continental USA via the US Postal service.
