[ForSale-Swap] Re: Inductor and variable caps

[Carl Huether]

Time to do some winter cleaning.

1.  Dual Section variable cap. 15-450pf each. Built by TRW for Heathkit in
the SB200/220 series of amps. Looks like a BC cap on steroids. Handles 1200W
plus in that application. Great for the Z Match tuner in the current QST and
many other projects.   $30

2. Single section double space BC frame. 15-110pf made by TRW for a National
Radio military receiver; NOS. Rotors are aluminum, stators are brass for an
almost NPO coefficient. End plates are split for fine tracking adjustment.
2;1 gear reduction with antibacklash gears, 1/4" shaft. Remove plates to
change the range.
Construction is such that a dual section could be built with minimal effort.
$15

3. 40uh inductor on a 2" by 4 11/16" ribbed ceramic form. #16 wire with 10
taps. It would make a great basis for any medium power transmitter, antenna
tuner or amp. A 2 turn shielded loop is inside the form; use for a sensing
circuit or remove. $15

All prices include postage in the USA. I will ship
international for my additional postage cost.

Since I have several of all 3 items quantity pricing is available.

Personal checks or MO are fine; use my CBA or the ARRL/FCC page for an
address.
EMail with questions, etc.

Thanks
