Default FS: Modulator, NIB Johnson Low Pass Filter

I very much prefer payment by PayPal, or by VISA/MC (which are processed by
PayPal for me). All prices are plus shipping. The weight stated is the
weight figure I will use to calculate shipping, it covers packing materials,
and sometimes I have to buy a box.

Homebrew Unfinished MODULATOR. Can use a pair of 807's. Modulation
transformer is a Merit A3113 (not sure about that last "3") 175 watts.
15,000 ohms CT; or, 6900 ohms CT. Secondary is 3000, 4000, 5000 or 6000
ohms.
Driver transformer is a Merit A3124. The filament transformer is of
unknown brand. I megged the modulation transformer. $39.00. 24 lbs.
