4-1000A - tested: 4-1000A $225 Tested at 14 MHz in a quality home brew grounded grid amplifier with 2900 VDC plate voltage and 950 watts output measured on a Drake W4 wattmeter with about 90 watts in. This is one of the the best 4-1000A tubes that I have tested. I can not read the manufacturer name so I don't know if it was Eimac. It would like much higher plate voltage (not available here). If you are not satisfied with the tube I will accept the return within 30 days if you pay the shipping.; Listing #1749198 - Submitted on 11/11/25 by Callsign N8EA, Modified on 11/14/25 - IP: 99-71-188-242.lightspeed.livnmi.sbcglobal.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
