I have this one:

good catch. I've been guilty of strapping caps together and in general being too trusting of the sleeve providing insulation equal to the caps working voltage rating.

honestly, I can think of no possible chain of events that would lead me to doubt Alex... it's just that simple.

Man, I forgot to add 4 1000uF/50V Panasonic FM capacitors (P12393-ND) to my last Digikey order... anyone happen to have some on hand, or about to place an order and wouldn't mind shoving 4 parts into an envelope and sending them my way?

now, who will be the first to try them out on Ray's new amp?

definitely possible, and seems like a good solution for you. You could work something out where you had the built-in DAC and then he ability to bypass it and use an external DAC.

lies!!!! it's my mod, all mine!!!!! mods, please delete this thread, or else I'll shut down the marce mod cash pipeline... i'll do it, I swear. look at spritzer's APL output transformers, it's like covered from head-to-toe with copper tape... very shiny.

no, like this:

yeah, I've been on and off that list so many times. The only thing that gets me off the list is modding things like baby monitors and other "useful" electronics.

what you need is a mil-spec wiping utility............................

does vodka and garlic count? this would qualify most of Russia.

well, the 2/3 marce mod doesn't include cryo'ing...

that thread still cracks me up... talk about back-pedaling...

heh... I would recommend using them as a weight loss program... My wife stepped on one of these and it wasn't pretty

yeah, a very nice thermal adhesive too. I bought them from here: http://www.sidewindercomputers.com/swmcbgamera.html I tried a few different ones out and found these to test the best. After cryo'ing the heatsink, you'll get about -.0001 C/W better as well. It's definitely worth it.

capsule form? that's the real stuff...

heh I like those heatsinks... beats the hell outta the Mouser / Digikey stuff.. I have some D2PAK form MOSFETs in my phonostage that could really use them. Nelson Pass had these mounted under the PCB and against the case and I didn't realize that until I finished my layout... yeah, they get real hot. Hint: video card / BGA chip overclockers make cool stick-on heatsinks.

Maybe markl should try the HA-02: http://www.head-fi.org/forums/f5/tube-y-tube-amp-owners-need-loaner-singlepower-woo-260560/ :rofl:

very strange. I ran that combo for a while without any problem. How much gain does your linestage have?

pj: Did you ever write up a proper comparison of the Bugle to your new setup? I'd be surprised if it was 10000% better myself... I think the Bugle can really hang.. Then again, I don't care for SUTs really...

I wonder if I could add some Dynamat to the chips as well ..................

fftt.. he doesn't even use Dynamat. If I was going to use something, I'd use bituman sheets. I've used these for speaker damping and they kick the crap outta any other damping sheets. They are quite heavy, so it would make the customers feel like they're getting more for their money.

lol... in all seriousness, this copper foil EMI/RFI tape from 3M is pretty sweet. I haven't tried it on any opamps, but the DACs I've used it (such as the TDA1543 in the picture) on I can definitely tell a difference. Here's a link to some general information. I plan on trying it to my PPAv2 opamps soon and will report back.

I'd probably build one of these: http://www.tubelab.com/Headphone.htm

you've heard of the Stax fart... now presenting.... the Stax lobotomy
