    and now for something completely different part 3

    Gotcha, thank you very much! Do you mean opposing transistors as in complimentary transistors? Google wasn't very helpful in that regard... Reading through the thread is a little overwhelming x)

    Ah sorry, I mean, which transistors should I match? Is it all of them?

    Apologies, this is probably a silly question, but what's the most important components to match? (And for the GRLV too...) I'm still a little new to this side of DIYing...

    Also, is matching a must for this amplifier?

    Ah, am I blind or is there not actually a 10k on the silk?

    Your BOM has 1k specified but I can't find that anywhere in the schematic. Is the 1k necessary? Edit: here's the mouser BoMs for the CFA2 and GRLV I created: CFA2 GRLV (30v) I think they're both correct but if there are any mistakes please let me know...

    goldenreference low voltage power supply

    Alright, I'll think I'll use a 100VA traffo and keep it at 35V for 10uF and 25V for 47uF for the tants then. Thank you for the help!

    Holy crap, it takes that much power?

    Thanks my dude. Also, I'm aware that 28-30vac is a good range for the traffo for 30vdc but if I want to power a CFA2, what va is recommended?

    goldenreference low voltage power supply

    Apart from the big caps (using 50v ones) and r8/r9 to 3kR, do I need to change any other parts assuming a 30v output? I assume the tants too, but would 50v for the 10uF and 35 for the 47uF ones be fine?

    KG Balanced Dynahi build discussion thread

    Ok, thank you very much! Would wirewound trimpots be ok to use instead of the cermet ones specified? Happen to have some lying around.

    Do the other specs of the LED matter or is it only the forward voltage (1.7V) that is important?

    I'm pretty certain they don't but I want to ask just in case!

    This is the hFE chart on the datasheet of the KSA992 (and should be identical to the grading system on the KSC1845). @kevin gilmore, do the 2SA1145/2SC2705 on the ss dynahi boards I have need to be matched?

    What grade are they? I'd love some if you can spare them!
