    The ultimate DIY? A Stax SRM-T2!

    For RK50, email/contact Justin [email protected] I got mine from him (for a pretty good price).

    The Multi Amp aka Dynalo Mk2

    How do you manage the heat? Is it getting too hot (> 50C)?

    Bought my set of DIYT2 transformers from Richard a few months back, just tell him the Gilmore DIYT2 set (http://primroseaudio.com/transformer-designs/) *** He gave me only a single 117V primary ***

    Pars, the plus is Rean NYS221. That extra front recess is for a guitar strap. I think NYS2203 looks nicer. Mouser got 'em all. Yes, standard SMD board. I moved everything off-board except for the XLR inputs in the back.

    KG Balanced Dynahi build discussion thread

    55C sounds about right (forgot what was my bias). My Dynahi runs at about the same temp after 30 min (measured via an IR-based meter, a few degs off here and there is not a big deal). Have you checked with Steve about where he got his tranny shieldings? I run with Anteks and they seem to shield adequately. Single-box saves quite a bit of space; if run two boxes, do consider umbilical resistance.

    Nice rework station! The price is pretty reasonable too, should have known about it six months back (when i bought my rework station). Any recommendation on desolder gun? Hakko fr300/301 any good?

    My hat's off to those who managed to solder on the qfn's. On my latest boards, could only solder the positive qfns, gave up on the negative. Will try to-220 tps7a3301 on the boards from the current GB.

    Well, if you can get the heat sinks to transfer some heat to the chassis (shimming extra metals on top the sink so it can get touch the chassis top), doubt that the heat in the channels would be a problem. My Mini's temp is about 32C with help from the chassis to dissipate the heat; without the chassis help, it was well above 50C. I didn't do any hole into my sinks. I see you didn't attempt QFN solderings with your new re-flow gun?

    Cheaper than WE300B reissued ! JAC Music got a pair for ~500usd, still pretty steep for a set of four.

    CFP2 is CFA (current feedback amp), right? Much different from Dynahi? I already have the Dynahi, wonder if it would be just a duplicate to build the CFP2.

    Part Sourcing Assistance/Advice Thread

    I got Sparkfun 303d station. Not the cheapest but the air pump in the base is better than in the gun, i think. Did all my smd's with it. Ebay got lots of choices but not sure which will support parts, warranty, complaints, etc.

    Good job on the QFN soldering! For some reasons, couldn't get the negative to work. I reflow so many times that I thinked may burn thru the regulators.

    KGSSHV Carbon Build Thread

    I like 009 more than 007MkII out of the Carbon. To me, worth the $$$. May be get a chance to listen to both before commit buying anything?
