    Sir
    Still waiting for your guidance on transistor equivalents including output for 777a

    I didn't reply before because the question you ask is already answered in the previous posts, except for the TO-66 package transistors which I did not replace (I have an idea for good substitutes but will not share that because I haven't tested for myself). There are no big mysteries for substitutes here (maybe except the TO-66 which I don't recommend replacing), just personal preferences like ksc versus ztx. Personally I went for the KSC1845 throughout the amp for almost all small transistors, although I do note that of late I'm becoming a fan of the KSC1815 for the additional current handling capability (but on the other hand the 1845 is listed with better robustness to voltages). The TO3s are listed in a previous post; I'm a big fan of the robust version of the MJs I used and I now use them all of the time even when it's way overspec.
