You are bidding for a pair (2 tubes) Cetron 300B Version 1990s Black Used Tightly Matched Pair excellent testing values with original boxes tested excellent on TV-7 at around 82-84/58 min good while new tubes are tested at 89-90. I tested them on my amplifier and they also worked flawlessly. Return is accepted if you pay the returning fees. Shipping is by DHL express with track and insurance. Again, the price is for 2 tubes 300b. Thanks
P/S: The shipping fees in the listing is by regular mail
(normally Vietnam post) taking from 12-25 days depending on buyers' local
customs. To some regions, it can take even longer than that. Besides, Vietnam
post is not always available to some countries in South America, Northern
Europe or Africa. Please ask me before paying. If you want to use express
shipping services like DHL, Fedex or UPS express taking 3-7 working days, you
have to pay an extra of around $60. Please let me know so that I can send you
an invoice. If the item(s) purchased may not arrive or be faulty, please don't
hesitate to contact me before opening cases on Ebay. I am more than willing to
reach to a solution and make you completely satisfied. Thanks a million
