April 1977 QST article
Hi Michael,
msg wrote: I wouldn't mind seeing that article too... if your address (minus underscores) is a valid one, you have mail in the '80s I built some common type replacements using jfets and bipolars and installed them in an HP scope..... 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...

I see huge lots of mil-surplus 6AU6's, 6CL6's, 6BA6's, 6AK5's etc. moving through the surplus channels all the time, still. Someday we'll run out but I suspect that transistors will be obsolete before we use all those tubes up! Tim. |

Oh, I figured as much, but I thought it would be a nice experiment to try
