You are looking at a strong as new Electro Harmonix 6550 EH output tube. It measures new at 100.0/9.1 and is in very nice physical and electrical condition. The getter is bright and unmarked. New measure on our AVO Kk IV tester is 87.0/9.0. I have another single EH 6550 tube listed as well.

All tubes are guaranteed not DOA. Shipping is by Australia Post and charged according to their rates for different zones around the globe. If you wish to check out the zoning and charges please visit auspost.com.au. The minimum shipping weight is 500gm, I pack tubes very well and I have only ever had one problem with damaged tubes in over 10,000 sales. There is a very small handling charge to cover packaging and handling. I do not profit from shipping and I wish I could charge less. I am a registered business and pay all the appropriate Australian taxes including 10% GST. 

Domestic shipping for this item is $12, if you are in Australia please Email me before purchase and I will adjust the shipping for you so you pay the correct amount. Overseas shipping with tracking is $28, though some destinations are more expensive than - Russia is $34 and Israel is $36. Shipping to the USA with tracking is cheaper at $24 because it is in a different zone from Europe. If you live in a cheaper zone I will refund the difference ASAP on payment. Please Email me to know the specific shipping cost to your country.

Please Email me if you have any questions about this item and I will reply as soon as possible.
