For sale: 4pcs tubes EL51 TESLA from 50sAll the photos and tubes I show you, are taken by me and belong to me. All tubes are measured, I chose 4 similar ones from 12 pieces for you.My Tesla BM215 measuring device is not an accurate instrument and shows conventional units of measurement.Due to unstable electricity voltage at my home, the readings have an error of 1-2 units.I recorded the minimum values of the anode current ( Ia ) without heating the tubes for more than 1-2 minutes.All tube bases are solid, some are glued again.The amplifier you see in the photo may not be working, I have not tested the tubes and for this reason I cannot say with a 100% guarantee that these tubes are working.I will make a secure package for delivery, but I do not provide any guarantees for items over 60 years old.But it is selling as it is on photos, without guarantee. Thank you for understanding. For buyers from the European Union , shipping costs - 20€Shipping to China and South Korea costs - 25€ Shipping to Japan, Hong Kong costs - 30€ Taiwan buyers: delivery takes more than a month...if you dont want to wait patiently for the item, please dont bid. Thank you for your understanding.
