I want to replace the vibrator in the pe104a power convertor, what solid state components do I need and how would they be installed.
I replaced the vibrator with diodes in a zenith table top, using the rest of the original parts in the vib power supply.i do not know if this will work on the pe104 supply.

thanks in advance for any info.

Here's the link to the final PE-104-A solid-state conversion.
Big thanks N6CAV

I have successfully converted my PE-104-A power supply vibrator to Solid State using a VBP-1 module. I have written up an article on the whole process on my website, with a working schematic and photo documentation of the process. Pardon any typos, as I have had a LOT of requests from other SCR-284 (BC-654) owner/operators on how to do this.

I want to give credit to N6CAV and KA6BFB (Craig and Dave) for their incredible expertise in working with me on this (an entire country apart I might add).

You can find the article on my site at http://m37.crwdesigns.com/radio-set-scr-284/ towards the bottom of the page. In the article there are links to a PDF version of the article and a working Schematic of the modifications to the vibrator to solid state.
