April 1977 QST article
Hi,
Does anybody have a copy of the April 1977 QST? The article I am interested in the the one by Howard Sartori, entitled "solid tubes, a new life for old designs". If somebody could scan this article, I would be glad to pay them. Thanks! Pete KE9OA |

Thank you Mario.............you are the best! I have always wanted to build
solid state tube replacements. Now, I am on my way to converting my Collins R-388 to a solid state unit. Pete "i3hev, mario held" wrote in message ...

Pete, the last time I did this, I had dual gate MosFET devices. These days they are harder to find, so I'd probably use two JFETs in cascade to get more or less the same effect. I vaguelly remember the article recommends dual gate MosFETs but I will admit, it's been a long time since I read it.

I will give it a whirl. I do have some of the dual gate devices on hand. I
have to do a board layout for each of the modules, that will have a pin field that has the same pattern as the tube base. Out of all the receivers I have / have had, I think the R-388 is still my favorite. Pete "Jim" wrote in message ... Pete KE9OA Wrote: Does anybody have a copy of the April 1977 QST?

Dual Gate MosFets are convenient for a tube replacement....
As I recall, I rectified the old filament voltage, regulated it, and made that the new "plate" voltage. Other than that, JFETs and, when necessary, Dual Gate MosFETs did most of the work. Well, had to mess with the "grid" bias resistors too. OK, so I used an audio Amp IC for the last part of the audio chain. Still, all in all, the conversions I did were surprisingly easy.

Not necessarily, but Windows has been subject to an extreme amount of code bloat, in comparison to some other OS's, which tends to make the effect of any disk problem worse for Windows.

Neither of those issues is the problem. It was a virus. I regularly make DVD
backups of all data whenever I format my hard drives, but in this case, I trusted that fact that I would be able to transfer all of my important data to my secondary (slave) hard drive. Unfortunately, when I reinstalled Windows XP Pro, the crummy operating system didn't recognize my backup drive unless I formatted it. To make matters worse, the stupid, stupid, stupid Western Digital "Data Lifeguard" software would not mount my backup drive onto the system unless I reformatted that also. There was no option to configure my backup drive into the system unless I actually formatted it and lost all of my backup data. It looks like Western Digital is following Microsuck's footsteps. I should have transferred all of my important data either to a DVD or to my Linux system. Never again a Western Digital drive! The fact remains though, that I still need a copy of that article from at least one of the 10 people that I was nice enough to forward it to. That would help me much more than the various "lectures" about what I should have done! Pete "Norm Mann" wrote in message news:EJstj.873$we5.858@trnddc02... "Bert Hyman" wrote in message ...
