    HC Bike/Cycling Thread

    There was definitely professional cycling back then (guessing in the '50s?). And well before that. Fausto Coppi, Jacque Anquetil, Gino Bartoli, Alfredo Binda. Legends. Lots of them.

    Balanced to unbalanced board

    The BC856C variants are the SMD equivalent of the BC556C... you'd have to get or make adapters to use them though. They don't handle as much power also (320mW vs. 500 for the BC556C).

    I’d you need an OPA445 in a DIP-8 package, the AP is pretty much your only choice. Does it work with other opamps? Your post makes it sound like it does. The OPA445 uses a standard single opamp pinout, from what I recall. Where did you source the ones you have from? Are they genuine? Sent from my iPhone using Tapatalk

    Apparently Dario Pegoretti as well, August 23. You cyclists will probably recognize the name. Heart attack at age 62. RIP! Sent from my iPhone using Tapatalk

    I would think the bike shop should be able to face it, ensuring that they are parallel? Or don’t they do that anymore (I’m used to steel frames). Sent from my iPhone using Tapatalk

    Uh, no it isn’t normal for bearings to feel gritty. Guy is a dumbass for even suggesting that! What kind of crankset!/BB is this? Sent from my iPhone using Tapatalk

    Part Sourcing Assistance/Advice Thread

    ^ This. Plus the Neutrik blanking panels are for a known standard jack series. I don't know if there is a standard IEC hole size (it seems that most of mine are all over the map), but that might make it more difficult to find. I know a lot of the chinese vendors on ebay, etc. all sell cases with the IEC cutout (presumably to a standard size), so perhaps someone does make some.

    The Multi Amp aka Dynalo Mk2

    As for an SE out, L+, R+ and gnd straight back to the power supply (not to the amp boards). Either use 2 conductors for the gnd, or a heavier wire (usually 24ga for signal, so maybe 20ga for the gnd). I wouldn't use an epsilon 12 with this, as it won't properly handle balanced signals. I'd use one of Kevin's balanced protection boards instead. 400mA sounds about right (don't recall exact figures, but it's probably here in the thread somewhere).

    Mjolnir Audio Dynalo 2 , just bought it.

    I presume those are LCD3s? You might do some searching for different pads (head-fi, though noisy, might give you some ideas).

    Yes, RIP Claire! I just read more about her this morning and it brought me to tears. She must have been a lovely person! Sent from my iPhone using Tapatalk

    The Multi Amp aka Dynalo Mk2

    On the mini SS Dynalo, to increase the gain a bit, would I want to raise the 25K some or lower the 5K? I would assume raise the 25K but just checking. From what I recall, the stock gain is 6 ((R feed / R in) + 1)? Going to an R feed of 39.2K would give 8.8 gain; 42.4K would give 9.4. Not sure I want to go up to 11 using 50K (49.9K). Also, would the compensation cap need to be changed? Is there a formula for calculating what that should be? Thanks!

    stax t8000 clone (well sorta)

    Being from Sweden, shouldn't that be more like 12mm (well, 12.7mm) instead?
