TUBES - 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.
