Before you get carried away on building new, check out

There may be a way to retrofit their "low-cost product line" to replace =
the orginal filters.

There is a difference.  Peter does more than rebuild old transformers.
There is also a market for -NEW- transformers out there.  And
believe me when I say that the amateur market is not Peter's
biggest customer.  And you would not believe the technology
in building transformers.

We need to face the fact that R-390 owners are just a fraction,
and a very small fraction, of a group (hams) that is also considered
only a fraction of the electronics world.

Unless you are willing to pay what a business would think of as a
reasonable cost, something we would consider too high, there just
won't be a big market for this stuff.  If there were, somebody
would already be doing it.
