Looks good Wayne. When I had my beard for 20 years or so, I couldn't stand it more than maybe 1/2" long. I'd be running for the beard trimmers with yours by now
Vicki, have fun at the gala. I love reading your posts...
We bought a 13" MBP on CL, nearly new for $1K. Probably comparably priced to the refurbs at the Apple store, maybe a bit less.
Apple Store refurbs
I bought my G5 Powermac on the Apple store, refurb and have never had any problems with it (3 years?). It looked new when I got it.
It appears that it trys to get new content from whatever area you are in, If you are in PMs, it tries to get new PMs, etc. It should always fetch new forum content, not be tied to the area you are currently in.
Maybe not in the same league (but maybe they are?) Odyssey Stratos. Like this one: My link
Or if you wanted a hybrid (tube front-end), Counterpoint SA-100 or SA-220. Here is an upgraded one: My link
EDIT: Odyssey is Symphonic Line RG1 IIRC
I think those are the prototype through-hole files that I have. They don't match the gb board exactly. I tried contacting Jacob, but no response. I used the contact link through HC... not sure if that is a PM or email. If anyone has his email address, we could use the eagle files for both versions. Any other documentation he might have (BOM for the SMD version, etc.) would be gravy. I asked Kevin and he doesn't have them.
^ probably the best compromise if you want to be able to run either way and there isn't a more elegant solution. Once I do some listening to it, I would probably decide I liked it one way or the other anyway and tweak it for that. End of problem.
The FET instability is more worrisome however. I've kinda put this down for awhile, but am interested to see what you encounter when you get a board (or more) built up and start looking at it.
I'm sure it does, and that is the reason for an opamp that can run from 30V rails. I still prefer to get offset as low as possible before relying on the servo for clean-up. And 160mV doesn't seem low to me. I can adjust it out via the pots, but there wouldn't be any quick switch between the two modes. I know Kevin told me you would need the servo for the local feedback option, so maybe there isn't any way to balance things out for low offset (without servo) for either feedback method simultaneously.
How are you guys coming along on the production version Doug?
I was just over at my brother's briefly yesterday, and he is still enjoying his immensely. Thanks for letting me in on the proto phase!
Tested it out this morning. A slight amount of tube hiss (barely audible with head < 12" from speaker), but no hum. Gone at all gain settings. And this is with the tubes cold, so it should decrease after a bit of warm up.
I need to publicly thank Alan (VivaVee on diyaudio) for his help in finding this. He is the same person who helped me fix my brother's power amp as well. Good guy.
Looks decent. I don't have any experience with them, but Ayoue seems to be well thought of. Price looks good as well. I would think this would be much easier than the flood and suck method, particularly in clean up Another plus for being able to localize the heat rather than having to heat the whole board up (toaster oven).
