Re: Oren Elliot latest "0219" series variable cap?
DeOxit is not cheap here either! We use it here mostly for scratchy pots, with the F5 formula having more lubricant compared to the D5 formula. They both remove corrosion and protect the contact

Dave,
I looked upDeOxit D5 from Amazon UK. Almost £30.00 for 142ml. This side of the pond we pay around £10.00 for 400ml of contact cleaner, with several good brands to choose from, excluding WD40,

Looking on the Mike’s Electronics Parts web site, I see three different air variable capacitors.
Is the desired part the 384 variable capacitor here:

Gary and Steve,
I had noticed a difference in older vs newer Oren caps also, although I saw no physical difference between them. I tried something on the 'older' ones that seems to work to freshen

Hi Steve,
<<< Where are you obtaining the latest 0219 variable caps--from the manufacturer or from Mike's Electronics? This is certainly a very interesting finding.

Re: FSL coil Q of 1162/46 and 660/46 Litz compared using HP4342A Q meter
I just checked with Mike at https://www.mikeselectronicparts.com/ and he says his current caps are the latest version "0219" so I just ordered one to try.
Thanks for this info, Gary.

Re: FSL coil Q of 1162/46 and 660/46 (added 330/46) Litz compared using HP4342A Q meter
I wound a coil using 330/46 Litz to compare with the other two. 21 turns gave 273.3 uH, quite a bit higher than the other two due to the narrower width coil. Probably 1 or 2 turns should be

I should add that my 140mm ferrite rods are Chinese rods, not Russian rods, and that the results may be different using Russian rods. I don't have enough Russian rods to do the experiment

Re: Gary's New 6" FSL Design
Thanks Gary for the detailed response.
When endeavoring to obtain the highest resonant signal output at a given frequency, the Q needs to be high as practicable. The audio fidelity will be somewhat

Great post and interesting comment on the wife finding the spoon, I think some might prefer we were doing drugs and not playing radios.
