Any one know what tube this is ?
I just got a bassman 135 recently and this tube was in one of the preamp sockets . It's a 12a something but the other letters are rubbed off . Anybody recognize the manufacturer ?
The pre amp calls for two 7025 's but when I checked I only found one and it was in the PI socket . The other preamp tube is just blank . Did someone not know what they were doing ? Haha
