I have managed to 'work' loose an initial core
lamination or two loose to get started by tapping
with a hammer and a flat-ended chisel ... and I used
to take a lot of this style transformer apart (from
tube-type TVs) when I was younger (as a kid) to salvage
wire!

I have also re-wound several transformers - adding such
things as additional windings for various assorted grid
'bias' voltages and tha like.

I've never used chemical means - perhaps someone else
has experience with that ...

Subject: [OT]: Help! disassembling transformer


Hello,

I have a moderate size mains transformer to be rewinded. Stricly speaking I
want to change secondary winding only to obtait voltage I need.The
transformer is a standard type core composed from "E" and "I" type
laminations.
The problem is that the laminations sit very tight and all the transformer
is well soaked with dope.
Probably I could disassemble the core with pliers and hammer ;) with brute
forse but assembling it back may become more problematic.
Is there any recipe which could help to do the job?

Thanks,

Arkady
