When I completed my ‘Jones 6L6 Push-Pull Oscillator’ project in the spring, I made a start on a new ‘spring-summer radio project’ which was to be based on some 1937 RK-39 tubes that had been gathering dust here for many years.
With an unusually sunny and warm spring, I soon found that my radio-bench time was being hi-jacked with a lot of outside yard work and getting all of next winter’s firewood split and stacked away before the really hot weather arrived.
I found myself working on the project in tiny bites, sometimes not making any progress at all during the passage of a week. Headway was also tempered by the fact that I’ll often deliberate for several days over the placement of a single component or the selection of one component over another. I find this slow pace and decision ‘pondering’ during the design phase of any project to be most enjoyable as it gets my old brain working more than normal, on things that really interest me.
I’m happy to report that my latest project is now complete and fully operational and ready for operation!
As usual, I have written and published a web page fully describing the project and some of the background details of the building process.
My ‘Building A ‘37-Style ‘RK-39’ Crystal Power-Oscillator' page can be found here.
Hopefully we can have a CW QSO with it in the near future!
Just as my shelf space for new projects keeps expanding (and quickly running out!), so does my main web site, "The VE7SL Radio Notebook". I have just added a new page to the site describing the construction of my newly-completed Jones Power-Oscillator using a pair of 6L6s.
If you might be thinking of building a 'Jones', you may find something helpful or perhaps find inspiration for a new project. The new page may be found here.
I'm presently building the final version of my RK-39 crystal power-oscillator ... but I have no idea where I 'll put it when finished!
