[Boatanchors] Want to buy some Parts For Receiver Projects

[radio_man at wbsnet.org]

Scott,
Haven't found any dual 365s yet but as alternative I do have some 3
section 330pf along with 4 section 25pf. Nice reduction drive for smooth
tuning. Quite small. 1/4" shaft.
Also, need to check, I have some Miller IF transformers, they are at my
other building.  Will see if can get to it this weekend. Also some coil
forms I think.
What value of mica trimmers you need?  Have several different
ones/sizes/values.
And, if you haven't got one, I have a Thordarson 22R02 power transformer. 
600VCT at 70MADC, 6.3VCT at 3A and 5V at 3A.  Along with LOTSA tubes....

> Hi, I’m looking to buy some parts for some home made receiver projects
that I am current working on and plan to build.  I’d appreciate if you
could look in your junk boxes and help me out with parts that were once
easily available in the 1960’s.
> I’d like to find:
> 1.  1 or 2 Miller 2112 365 pF dual section variable caps.
> 2.  Some Miller 455 Kc IF transformers, interstage like a Miller
1312-C2,
> and output, preferably the newer slim chassis mount version like a 12-C2
3. Some Miller screw adjustable coil forms or coils like the 4411 that
go
> up to maybe 350 or 400 uH.
> 4.  Miller MD-8 two speed vernier dial.  I’ve never ever seen one.  Has
anyone ever used one?  I see it on the front panel of the HB-67 in the
1967 ARRL Handbook.
> 5. A couple voice coil transformers, small for a small receiver,
preferably with multiple output impedances
> 6. Compression variable capacitors
> I am currently working on a 3 tube 40/80 meter superhetrodyne receiver
first published in QST April 1966.  I built a duplicate of Lew McCoys
circuit last Spring, got it working a bit, but had a lot of struggles
with

because there was much more to learn, so I am now building a breadboard
version of the circuit that is spread out, separating sections, reducing
cross coupling of oscillators, using coax for section interconnects,
shielding, etc.. I put up a Youtube video of it last night.

crystals.  Once I’m done with the breadboard I want to go back to my
compact version and figure out what’s wrong with it.

> If you’re no longer building, or have spares,  how about giving me a
chance to use those parts.  Many thanks! Let me know what you have. 73,
