Procusase duas valvulas/Looking for two valvules

Mi nombre es Priscila, de Brazil. Yo tengo uno organo electronico Hammond modelo L-122 movido a valvulas. Duas valvulas de som están paradas. Adonde puedo encontrarlas? Especificaciónes: pre 12AX7 y salida 12BH7. Gracias. xoxoxoxoxoxoxoxoxo I have a Hammond electronic organ model L-122. Two of the sound valvules are not working, so I don't have any sound. I'm sad it used to have a fantastic sound. I'm looking for someone to help me to find the valvules. They are a pre-sound 12AX7 and out-sound 12BH7. My name is Priscila and I live in Brazil.
