Tuner problem My tuner on my Marantz Model 19 receiver was dead. I took it to local vintage tech. He restored it some what. It works with the mute button off, but has trouble picking up stations. Tech told me he couldn't find parts he needed. He said they were motorolla transistors #334-1018 and 334-1038. I am not sure if these are marantz numbers or motorolla. Tech said that if I had any luck finding the transistors that he would install them for me with hopes of fully restoring my tuner section. I must say he did not give me a good vibe as far as actually being able to locate these parts
