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 |

April 1977 QST article
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.

April 1977 QST article
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?

I wouldn't mind seeing that article too; in the '80s I built some common type replacements using jfets and bipolars and installed them in an HP scope which was the fastest I had at that time. I still have a real Fetron in my desk drawer. Regards, Michael |

Hi Michael,

I think that we all may want to learn the knack: in a near future this will probably be the only way to refurbish tube equipment...
