Like new, in original package!

I have a SINGLE KR Audio KR-274B for sale. I am the original owner, and used this tube for a grand total of about a week, so maybe 10 hours on it, in my Woo Audio WA6-SE Gen 2.

I've since moved on to other tubes and this rectifier sits unused in the box.

Price includes the tube, original box, included paperwork, and BASIC shipping. If you want insurance, signature verification, etc. that will be extra. PayPal Goods and Services ONLY due to some recent fraud activity going on here. Please have some well-established feedback and post history as I no longer deal with new account holders.

Thanks!
