Years ago a tech for a local paging operation commented that
having Peter Dahl Company rebuild the transformers was
cheaper than getting replacemnts. The economics may have
changed since then, but it might be worth:
(a) pricing out the shipping, and
(b) dropping Dahl an email.
de Mike WA6ILQ, who still wishes that he had a picture
of the "quick fix" on the Collins TX at KALI (10kw AM)....
The transformer HV winding had shorted to the case.
The fix until Collins could get a new one to them was
to stand the transformer on two 4x4s wrapped in a
plastic tarp, and a LOT of warning signs.
