F.S. 4CX1000A Power Tube: §§§§§§§§§§§ pending payment. §§§§§§§§§§§§§§
I am selling one 4CX1000A tube that I had kept as a spare to my ACOM A1500 amplifier. I sold the amplifier about a year ago and no longer have a need for this spare. It performed very well in the ACOM1500 and was my backup tube. I am asking $360 shipped and insured to anywhere in the continental USA. I accept Personal Check, Postal Money Order or PayPal (Friends and Family).

Eimac 7580W / 4CX250R: Offering this from recent estate tube lot - cosmetics indicate either NOS or very, very low hours.
( Taken from Eimac Spec Sheet ):
The 4CX250R/7580W is designed specifically for use in Class AB1 linear amplifiers where shock and/or vibration preclude the use of non-ruggedized tube types. 6.3 v filament same as the 4CX250B. The 4CX250R/7580W will ty[pically deliver more output in most linear amplifiers which presently employ the 4CX250B...
My TV-3B/U tube tester doesn’t cover this one, so it’s sold As-Is / No Return.

8874 Tubes Matched Set New: Here is a matched pair of lightly used Eimac 8874s with boxes and packaging. Tested for full power out + in an Alpha 76A.
The previous owner burned them in for 50 hours and then set them aside as spares. These are long life tubes. If you used them in an Alpha 76A for 12 hours per week, they’d typically last over 35 years.
$450 each or both for $600 shipped. Will be expertly packed and shipped UPS insured. Will ship WW for a nominal additional fee.; Listing #1760163 - Submitted on 02/26/26 by Callsign K1FIE - IP: 12.47.128.137; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
