Re: 2235 Repair having no power

Hi,

Since it (the transformer) was broken anyway, I opened it up to see if a rewind of (most likely) the HV winding would be possible.
First of all, it was completely potted, so already quite difficult to open up.

And, on top of that, the HV winding in this version of the transformer turned out to be physically in between the pins 12,13,14,15,16 and pins 17,18,19 winding.

So no "easy" access to the HV winding without destroying another winding first.

Here are some pictures I took: https://groups.io/g/TekScopes/album?id=254000

So, still looking for a TekTronix 22xx T948 transformer... :-)

Saludos from Spain,

Leo
