Oh... you're supposed to use solder on these? With heat? Seriously, for the production run or whatever, this could be a concern. If someone can f something up, they will. Poking around on the board, etc., they could be bent into contact with one another. The caps protect them somewhat.

Mike, my condolences. Me: heat turning up on project at work, but it will be done in a week. Have gone riding (bike) every night after work for 20-30 mins (5-8 miles). Up to averaging 16 to 18 mph, but bike path can slow things down. Have to be mindful of the kids, walkers, joggers, etc. I'm sure this is not up to Chris' (dreadhead) standards Haven't seen him around here for a bit, hope all is ok.

My brother brought the rest of the parts over yesterday, so I got started on building this. Looking at the MUR810s, I assume that the tabs of D5 and D6 touching each other would not be a welcome occurrence? Anyone do anything to safeguard against this happening?

Fortunately I never even saw the red vodka, not that I would have had any... Beer or red vodka... hmmm, tough decision

That reminds me. I wanted to meet Pete Millet at CJ, but never did. CanFest, not so much.

Happy Birthday Birgir!

Happy Birthday Mike!!

Coupling caps: e-speakers is out of 4.7uf; Madisound carries them (Clarity Cap SA 4.7uf, 630V). 35 x 38mm. I know I saw a post or one of the emails discussed max physical size, but I assume the ones from madisound are fine?

Happy Birthday!

Yep. That ad auction had cunt written all over it. Reminds me of test equipment sellers on epay that say they can't tell if something works as they have "no way of testing it". What business are they in?

Yeah, that knob is way nice. That is titanium? BTW, what ever happened to that guy on hf that was doing knobs? Seems like he disappeared, but I guess I haven't been over there much (at all) lately. I think he did a titanium one or two...

The order acknowledgment that my brother got from RadioDaze included the following: *If you have ordered a Hammond product there will be some additional time needed to get it from them or have them ship it to you, so please be aware. So I am guessing they do the same thing. I ordered enough resistors that I can do R2 until the choke shows up. I suppose the footprint, etc. on these is proprietary, so no alternate part/supplier other than Hammond.

All of the ones that Mouser carries are E-C-B. ON, STM and Fairchild. ON and STM have the pictures in their datasheets showing the back (metal tab), but when looking at the plastic front, are consistent in pinout. Parts are on order. I take it the preferred build is with the C-L-C filter in the PSU instead of the C-R-C, and to use the CCS? Hammond choke ordered from RadioDaze. We'll see how fast they are. I also had Craig order the Pana TS-HC caps from Mouser. They do carry the TS-HA as well, but do not have them yet and delivery was early August (8-9-2010). I substituted a 47uf cap of the same series as the 33uf one that was backordered also (C5 IIRC).

Happy Birthday!

Also, C1L/R: I assume 250V is too low for these in case Q1/Q2 were to blow. I have a ton of MKP10 0.1/250V around.

I assume the Fairchild 512-MJE350STU may be used in place of the ST parts in the Mouser BOM that are backordered? After my recent experience with ST regulators, I avoid them like the plague Also, the 33uf / 50V cap listed in the BOM is backordered as well. I haven't measured the LS on the board, but from the pic I assume that 5mm won't work (Mouser stocks the Pana FC in this value, but it is 5mm instead of 2.5mm LS).

Didn't see this in the parts list: what is IC1? LM317? Think I may be out of them, so wanted to make sure to order some more.

Kit showed up today. Guess I'd better get busy! Thanks Doug and Tom,

Homepage has always been empty. My normal link in whatever the URL bar at the top of Firefox is set to go to "http://www.head-case.org/forums". Starting sometime yesterday, this now is rerouted to www.Head-Case.org - The Front Page, which goes to the empty home page.

Yeah, he wasn't one of the ones I was paying attention to, but I'd have to agree. "I can hear so much air around Pigpen <gasp>"

^ Was only planning on doing one.

The Mouser BOM I got from Tom appears to have quantities to build two amps... two IECs, etc. Was this intentional or am I misreading things?

I wonder if you could "persuade" Aavid to either send you samples (was it 60 of them ), or sell them direct to you? I would guess your credentials are good enough that it might work. Heat sink producer Aavid Thermalloy - World Leader in Thermal Management
