GEC VT60, Cossor UK, OEM to GEC print word; features the same as 6L6G/KT66/EL37/350B (but different pins, can not be directly replaced, need to add adapter), the price is much lower, is DIY Very good choice! Now there are people selling 807 to 6L6 adapters on the Internet. You can buy adapters on the Internet, you can use 807+ adapters, you can directly replace 6L6G/KT66/EL37/350B Now the price of 6L6G/KT66/EL37/350B is very high. It can directly replace 6L6G/KT66/EL37/350B with (807/ATS25/VT60 + adapter), you can enjoy the exquisite sound of early classical tube, but the price is a lot lower... 

This is the earliest British White Ceramic VT60 , the sound will be more refined than the average American 807 sound, a lot better!
