Description
This auction is for a Tung-Sol 5881 amplfier tube. Tested on my calibrated Hickok 600A tube tester with plate ammeter. It tested a little below the standard of 5000 umhos. #4 tested at 4800 umhos with 44.3 mA plate current. This is at 150 Volts, which is what voltage the tester uses. I do not do returns. I have no idea the how the buyer intends to use, test, or does to these tubes. Bid accordingly. I will offer free shipping in the USA . No international sales. Thanks for looking.
