Howard 436-A Receiver........$150 OBO plus shipping
This one is out of my personal collection and is featured on my Howard 
web page which I created several years ago. The Howard Receiver web page 
can be viewed here. The Howard 436A is an 8 tube receiver covering 540 
kHz to 43 MHz. It was manufactured in 1941 and 1942. It has an internal 
speaker. This one was made in 1941 as indicated by the schematic on the 
bottom of the radio. This radio is unrestored and does work on all 
bands. The BFO also works. Cosmetically it is OK with some minor surface 
rust. It is pretty rare to see a Howard receiver that does not have some 
surface rust and even more unusual to find one with a dial that does not 
have some rust. I have owned this receiver since the mid 1990's and need 
to start lightening up my collection. Includes a schematic.

Airdux Inductors - I have a significant quantity of the 50 uH inductors 
and half a dozen of the larger 60 uH ones.

50 uH Air-Dux Coil for Transmitter or Antenna Tuner - NOS............$30 
plus shipping
This is a new old stock inductor. Every other turn is indented making it 
east to make the taps.
I measured this at roughly 50 uH. The physical dimensions excluding the 
plastic mounting plate are 5 inches long and 2 inches in diameter with 
roughly 11 turns per inch. The plastic mounting plate is 6 inches from 
end to end.

60 uH Larger Air-Dux Coil for Transmitter or Antenna Tuner - 
NOS..........$45 plus shipping
This is a new old stock mil-spec inductor. The one you receive will 
still be sealed in the original packaging. This one was removed from 
photos. I measured this at roughly 60 uH. The physical dimensions 
excluding the plastic mounting plate are 8 inches long and 2.75 inches 
in diameter with roughly 7 turns per inch. The plastic mounting plate is 
9.5 inches from end to end.

Millen 90810 VHF Transmitter....$25 plus shipping
This is a project or a parts unit as it is missing parts.

Vintage Leader 3" Oscilloscope LBO-32B with Original Manual ....$30 plus 
It's a Leader LBO-32B 3" Wideband Oscilloscope. I believe this is one of 
the first Leader scopes to be imported into the US from Japan in the 
1960's. The scope is in nice shape and it does work. I was able to see a 
sine wave when I hooked up an audio oscillator for a signal source. 
Includes the original manual.

RCA Weather Radar Indicator AVQ-50.....$40 plus shipping
Don’t know anything about this -untested

Collins Radio Fundamentals of Single Sideband Book - $75 plus shipping
Good condition except the upper left hand corner has a slight tear along
the edge. This can be seen in the photo. Pages are clean with no 
markings inside.

Set of RCA Tube Handbooks...$60 plus shipping
I believe these are from the 40’s.
