Re: Peerless Transformer brand name.

Hi Chris:

The easy one first. Re: R-080. The price of this transformer is currently $80 each.

re: power supply filter choke for cap input. I ran a custom job as I could not readily think of a stock unit that was ideal.

Here are some particulars on the choke.

L would be nominally 18 henries
dcr would be approx 84 ohms
designed to carry 75 madc

my focus here was not low dcr as a virtue in-and-of-itself.
The lower DCR (lower than the 250 ohms you spec) was the
byproduct of designing the choke to operate at a very low
flux density with only 9 degrees C temp rise.

So the unit will run cool, it will operate in the at-ease range
magnetically, and it won't pollute two square feet of airspace with
strong radiated magnetic fields.

Price for these guys would also be $75 each. Size of the PS filter choke would be the same size as the R-080 except that it would mount in a horizontal brass channel frame.
