    A Higher Voltage DIY Discrete Op Amp - In the Style of the DIY FE 2022

    There are maximum transient dissipation chats in most resistor data sheets. For example P.8 of the attached for a 1W MOX. Individual decision how safe one wants to be. Patrick .

    Am in need of 2SK333-E or-F For SAE 202 Amplifier

    2SK332 is rated at 40V, as opposed to 80V for 2SK333. D grade also has lower Idss than E or F Grade. Patrick
