Specifically, I couldn't find the ICI LM308, so I changed it with CA3130. Similarly, I'd to exchange the transistor 2N5458 with NTE312. I assume my challenge lies in my inadequate option of possibilities for equally transistor and ICI. Could any person advise some alternate options?Ju? w niedziel? eighteen maja Polacy zdecyduj?, kto obejmie najwa?n
