Hello everyone. I¡¯m new to electronics. I¡¯m fascinated and overwhelmed with the subject and hoping that I can fit all this information in my brain! I always wanted a Tek scope and I bought a 454 that seems to run ok with nothing more than a quick signal generator test. I¡¯d love to preserve this for as long as possible and restore it but I have a new fear of eventually replacing a tunnel diode. The manual says ¡°part #152-0310-00 similar to 1N3758.¡± NTE claims that the NTE5804 is a replacement for the 1N3758. Is it? Will it work? If that¡¯s my only option, what would be different? Thanks in advance for any help offered.
