I decided to create a new topic, since my appeal in the old threads was not successful.
I got the N7B, which has one of the V-Fets destroyed. In addition, a pair of bipolar transistors, contacted with it and, possibly, the fusible 330 Ohm resistor, should be replaced.
I have found replacements for bipolar transistors, and I have a suitable V-Fet (in which I am certainly lucky).
But I still can't find a replacement for the fusible resistor. More precisely, I can’t find it with the parameter I need: 330 Ohm, 1/4 W. Can someone show me to a source?
I also read a lot of literature available on the Internet and came to the conclusion that no one really knows what distinguishes them from ordinary metal film resistors. Moreover, it seems to me that by designating the resistor as a safety resistor in the circuit, the author of the circuit simply indicates that this resistor has the function of a fuse, in addition to the main one.
What I mean. For example, in any electronic device, you can always replace a lower power resistor by a more powerful resistor with the same resistance (the main thing is that it fits in size). But in the case when the resistor is designated as a fusible resistor in the diagram, it is not allowed to replace it with a resistor of greater power. If I'm right, then replacing these fusible resistors to reliable 0.25W 330Ω metal film resistors will solve my problem.
Can anyone support or refute me?
I would be grateful for any information.
