Hi,
I'm experimenting with a filter based on the Buchla 291 voltage controlled bandpass filter.

The filter uses 2n3958 transistors for input and output buffer and I would like to replace them with something more available. I tried replacing them with a normal TL082 in LTSpice and it seemed to work just fine. However, I'm not knowledgable enough to pick up on the finer details of the characteristics. Is there another opamp that would be more suitable ? Is there a modern matched transistor pair I should try instead ?
