cyto Posted March 15, 2022 Share Posted March 15, 2022 Mullard M8100/6AK5, 2 tubes $25 shipped via USPS in the US. I thought I sold all of my tubes that I don't have a use for but I just found these in my tube stash. I bought quite a few of them from Langrex in 2018. I sold the amp that used them (Yaqin MS-20L), and thought I sold all of these M8100s. I have no way to test them so they are sold as is, I know they worked when I had the amp but I sold that 4 years ago. They probably have between 100-200 hours on them, maybe less. These were extras, I know I used them to make sure they worked just not sure how long. They are NOT a matched pair. PayPal only. 1 Quote Link to comment Share on other sites More sharing options...
