These are a matched pair of Tung-Sol 5998 power tubes. I purchased these NOS last year from a very reputable tube seller and have put 50-75 hours on them. In my WA22 they are dead silent after burning them in, and sound absolutely wonderful (as you'd expect from 5998's).

I am thinning the herd of my large power tube collection in anticipation of selling my WA22 in a month or two, so I'm selling these before I can regret the decision!

$300 shipped via Zelle or add 3% for PayPal G&S. These will ship via USPS with insurance and tracking. Thanks!
