Yikes. I've mostly seen it with PL509 tubes and maybe the occasional 6KD6. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

Well, it certainly won't help you build the next thing. ;) I try and keep fingers on both sides. For example, I both _designed_ the entire home for my son, doing all of the engineering calculations required, as well as personally dug the foundation (alone), laid the foundation boards and placed the rebar, added rebar clamps, built a cubic foot wooden box to hold and measure gravel and cement, and mixed and poured it. I think _all_ is important, theory _and_ practice. >The theology training I do not have, sometimes I wish I did. But got to >retire first ;-) hehe. Well, I have a million recommendations there, too. There's a great web site now that actually places up the photographs of various fragments of source materials, for example. Lots to study, there. I can assure you of one thing... if and when you ever get around to doing that work for a while, your entire perspective WILL change. No question. I don't mean to suggest it will change your beliefs -- my favorite teacher of theology was a Catholic nun and she would certainly run rings around me on this subject. So you will hold your beliefs, likely. But I can assure you that some facets of how you think about it will markedly change from the experience. >> And card games appeared to also be the usual fare for us >> Swedish family types, though I've long since dropped most of >> that habit. ;) > >One of our house rules: We never play for money, with anyone.

The author of "40 Days of >Purpose" wrote something that kept ringing in my mind: "You can do the >umpteenth bible study but at some point you've got to take what you know >and get out there with it, and do stuff", or something like that. Well, don't do the umpteenth. Just the first, second, and third. If you are arguing that ONE BOOK is a dedication of your life, well.... I just don't know what to say to that. Jon

The trick is knowing when it's cheaper overall to just purchase a product or service. :-) In personal life, for most of us this choice is clear-cut (it's only folks like Warren Buffet who would very likely be losing money if they chose to build their own home), whereas with businesses it seems common when small businesses struggle to grow beyond a certain threshold due to the founders being unwilling to risk others starting to make some of the big decisions... or somewhat alternatively, trying to develop all their skills internally when it'd be much cheaper and faster to hire a good consultant.

There are people finishing their BS in their 50s and later. I was over 40. The bottom line is never quit, never say die. And then one day you graduate. Trust me that can be a delicious moment. Especially if there are/were family/friends that did not believe you could make it. |
