I priced the tube about 1 1/2 years ago. Contact EIMAC sales. I believe their quote was on the order of $600 - $700.

RE: [Elecraft] Just Wonderin'...
Hi; 40-50 ma of grid current should get you about 1500 W out. Don't over drive the tube and it will last for years and years. Eimac tests the 8877 key down at 30 MHz , 3kw for hours before it's sold. It's a very good tube. pete, kn6bi -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of [EMAIL PROTECTED] Sent: Saturday, October 20, 2007 1:06 PM To: Andy - GM0NWI; 'Elecraft Discussion List' Subject: Re: [Elecraft] Just Wonderin'...

Eimac is a division of CPII (Communications and Power Industries, Inc.). Richardson Electronics is one of the primary distributors of new Eimac products. These tubes can last a lifetime in Amateur service if treated with respect. I don't know about this particular tube, but there is a considerable market in used power tetrodes on the web. You can sometimes get a kW level power tetrode with half its service life left for a couple of hundred $.

RE: [Elecraft] Just Wonderin'...
Hi Bob; That's correct, the 3CX1500A7 and D7 are completely different tubes. My remarks were from experience with the 3CX1500A7, the 8877. I don't know anything about the D7. If the tube is a 3CX, then it's a Triode (unless the coding has changed). If you're interested, you might have a look on the Eimac WEB Site. I think it's kept current. CPI and Eimac/Varian have business offices in Palo Alto, CA. Richardson is not the only vendor for the 8877. I don't know about the D7. pete, kn6bi -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of rrkrr Sent: Saturday, October 20, 2007 3:12 PM To: Robert Dorchuck W6VY Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] Just Wonderin'...
