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.

I am going to throw this out there, but be warned I am not an expert by any stretch of the imagination. I have a working SCR-284 (got very lucky) and I am searching for a replacement in solid state for the vibrator. I have been following a thread on a different forum, where they used this module-

to rebuild a vibrator to use in a similar radio.

Here is the link to the PDF on how it was done for a DY-88 Power Supply for the GRC-9 Transceiver

Now if you can figure out how to do this for the VS-3 in the PE104A and show how it's done, showing the correct assembly instructions, it would be greatly appreciated!!

I also found an online source for the VBN module.
