luvdunhill Posted April 29, 2012 Report Posted April 29, 2012 you want a (room temperature vulcanizing) RTV that is suitable for PCBs. GE/Momentive make good ones. Google is your friend. Fry's sells it, of all places here in Texas.
Pars Posted April 29, 2012 Report Posted April 29, 2012 I had used the plain old GE Silicone II in clear before. Many of the caps in the Counterpoint pre I used to have were affixed using clear silicone (from the factory). As long as it is low odor it should be non-acidic. From a quick google of electronics-grade silicone, it looks like GC has one for a reasonable price (<$5 a tube).
ujamerstand Posted April 30, 2012 Report Posted April 30, 2012 Just out of curiosity, if I want to form a thin circular gasket using RTV, what would be the best way to achieve this?
guzziguy Posted April 30, 2012 Report Posted April 30, 2012 I got some email from Howard Electronics today. Here's a tool for you serious diy'ers.
deepak Posted May 1, 2012 Report Posted May 1, 2012 Any suggestions for a reliable vendor for SSM2210 duals (PDIP preferred, but SOIC will work)? Found
luvdunhill Posted May 5, 2012 Report Posted May 5, 2012 Anyone keep track of the PcX discount specials? I'm wanting to get some Caps and am waiting around for the next special. If anyone happens to notice the announcement or has a feeling when it would be, perhaps you could post here?

If anyone happens to notice the announcement or has a feeling when it would be, perhaps you could post here? x2 also have some caps I need and waiting for the next 20% off sale. How much do they charge for shipping to the US for small < 1 lb orders via the cheapest air mail?
Lil Knight Posted May 5, 2012 Report Posted May 5, 2012 Did you subscribe to their newsletter? Normally they will send emails about the sales going on. https://www.partsconnexion.com/optin.htm
dsavitsk Posted May 5, 2012 Report Posted May 5, 2012 Soniccraft has many of the same caps, and tends to have the same sales. They list their specials at http://soniccraft.com/specials.htm
n_maher Posted May 5, 2012 Author Report Posted May 5, 2012 Did you subscribe to their newsletter? Normally they will send emails about the sales going on. https://www.partsconnexion.com/optin.htm which they just did 5 minutes ago.
RudeWolf Posted May 10, 2012 Report Posted May 10, 2012 (edited) Due to unavailability of Dynalo PCBs I'll be building one on a perfboard. I have a question regarding the 2sj74- as you most likely know there are two versions- BL and GR. Which one should I use? I'm using this schematic- http://www.elfaforum...46&d=1336591768 Also as this is my first major DIY project- if I stuck to the parts shown on the schematic- with what gain I'll end up? I'm looking to drive my HD650, so 8-11X would be plenty. Edited May 10, 2012 by RudeWolf
Pars Posted May 10, 2012 Report Posted May 10, 2012 BL if you can get them (same for 2SK170). Is Amb out of Dynalo boards? I may have one laying about that I probably won't need (the original DGardner boards, not the ones Lil Knight had run). Stock Dynalo gain should be fine; I've never adjusted the gain on any of mine and they have been just right for all the phones I've thrown at them. Note, I didn't look at your schematic from work.
RudeWolf Posted May 10, 2012 Report Posted May 10, 2012 Thanks for the info! Too bad that some sites doesn't specify which version they are selling. In any case I'd be happy to buy a couple of Dynalo boards for a tidier setup. Maybe I'll power the whole thing from a Sigma22.
Pars Posted May 10, 2012 Report Posted May 10, 2012 I probably only have one (which is 2 channels)... I'll take a look tonight and see what I have left.
luvdunhill Posted May 10, 2012 Report Posted May 10, 2012 (edited) I'd contact this guy and see what he can do for you: http://www.diyaudio....-class-amp.html Perhaps just send the Gerber's to BatchPCB and get some one-offs made, or use the part position for your own veroboard layout. Edited May 10, 2012 by luvdunhill
RudeWolf Posted May 10, 2012 Report Posted May 10, 2012 Sure, Pars- take a look. I'm building a two channel and was under the impression that 1 channel=1 board, if it's a stereo board then I'd take one. Dang, that must be the smallest Dynahi I've ever seen on diyaudio! I'll contact that guy If I get any more questions regarding the build.
Pars Posted May 11, 2012 Report Posted May 11, 2012 Sorry, forgot to check last night. Just sent myself an email to remind me...
deepak Posted May 11, 2012 Report Posted May 11, 2012 Didn't know where else to post this, but RIP PCM1704 http://www.ti.com/product/pcm1704
Pars Posted May 12, 2012 Report Posted May 12, 2012 RudeWolf I do have (2) of the Rev. C Dynalo boards left. I could part with one. PM me with your address and what you consider fair and we'll go from there. BTW, the link Marc posted was a Dynalo, not a Dynahi.
dsavitsk Posted May 12, 2012 Report Posted May 12, 2012 Didn't know where else to post this, but RIP PCM1704 Sad, but have you seen the price on the 1704 lately? And you need 4 for a differential design? It looks like they will be available for the foreseeable future.
luvdunhill Posted May 12, 2012 Report Posted May 12, 2012 Ok, I have figured out what I need. Anyone have a recommendation for a flush mount pin socket? Also, called a miniature spring socket? Anyone used these before?
jezz Posted May 12, 2012 Report Posted May 12, 2012 What's different about the PCM1704's status? It's been NRND for a very long time. Compare that to the PCM63, which is explicitly marked as obsolete -- http://www.ti.com/product/pcm63
