A small selection of ECC81 preamp tubes. The first two types are new production types from JJ, Slovakia and Shuguang, China. The rest are premium long-life NOS tubes. The first is a US-made type called 6201/12AT7WA. The next two are not really true equivalents, but they will work well in most cases (for audio). They are the US-type 5965-A, made by GE, and the European type E180CC/7062, made by Amperex/Philips. ECC81 = 12AT7 |
