SX-28A Front Panel gasket material identification?
Hi Folks,
I recently acquired a SX-28A. Externally and with bottom covers removed appears that it hasn’t been opened up in decades, if ever. Not even close to applying power, just making initial assessment. Controls, knobs & switches, appear to operate. The one thing that does not function is the main dial; the dial does not rotate. Lubed the tuning engine a bit without disassembly yet. All gears appear to be rotating. Everything except the dial hub and dial.?
I opened up the case and slid the chassis a couple inches. What found surprised me. There is what appears to be a cork gasket across the top between the faceplate and case, perhaps sealed long ago with the brown or black permatex gasket sealer.?
Over time the gasket and sealer have melted, liquified and hardened into something awful sliding down into the main dial and cementing the dial in place, even running down the dial edge. Picture attached.
Has anyone seen this before?
What can I use to get the dial free from this stuff and clean it up without ruining the dial itself? Alternately, does anyone know where to find an original, or reproduction dial. Hate to go with a repro but depends on if I can salvage this dial.?
Thanks in advance for any advice ?

I was watching an episode of "Elementary" (modern-day Sherlock Holmes set in NYC) and Sherlock had an SX-111 mounted on a shelf on the wall. There was no speaker, however.

Several years ago the Ohio taxation department showed up at the Dayton Hamvention and handed out tax documents to all selling anything including Joe (non business) Ham selling out of their trunk in the flea market.? Many people laughed and threw the paperwork away.? Some packed up and stopped selling and some left the show cursing.? One particularly annoying demand was you could not price something at $10.00 and say tax included.? You had to charge tax on the posted price.? So many displayed the price like this:
$9.30 + 0.70 tax = $10.00
Just to p*ss of the taxation officers.??
It worked, and there was nothing that taxation could do about it.
Odd thing is that taxation never showed up in future years.? Some hams have "connections" and I suspect the tax man was told to say away.??

Something to watch out for although I don't think they are particularly common in Hallicrafters geR Re flat molded paper caps.? These were used in place of mica caps especially in some ww-2 equipment.? Most seem to have been made by Micamold and SolR, both of whom also made regular mica caps.? ?These flat caps look a lot like micas.? Whatever their virtues, if any, when new,? they should be replaced on sight now preferably with modern mica or plastic film caps.? They were used when mica was in short supply and were evidently acceptable for some applications like RF bypassing.

While mica caps are more reliable than some other types I have found bad ones The drift may be the result of "silver mica disease" where the silver plating oxidizes and migrates across the edges of the plates.? This can cause both permanent? change in value and a rapid fluttering change. Most of the bad ones I've found are the older molded type, not often the more modern dipped type.?

I can't claim much experience with this where hallicrafters is concerned, however I also restore vintage televisions ('40's and very early 50's) and until about 7-8 years ago one could normally assume micas were ok. Now they seem to be bad at a very high rate-- shorted, out of tolerance,? or unstable. It seems they have reached the age of failure at this point. I haven't noticed a particular style or brand being better or worse than others although the higher the voltage, especially in terms of AC signal the more failure prone they seem to be.
Mike, ? It’s very unusual.? A lot of these are wack-a-doodle.? Bizarre readings, all over the road.? A few, however, are just fine.? Never seen this many bad ones in any one radio. ? 73 – Steve, KW4H ? Wow, that is interesting.? I am going through an SX-100 and it did not even cross my mind to check the old micas.? Typically once they are placed under voltage for some time, their ever so slightly skewed value does not shift around. To replace any out of tolerance ones with new ones may mean let the new ones cook under voltage for some amount of time before aligning the radio. ? Thank you, ? Mike W5CUL? ? ?

"Fair Market
Value" is a term used to estimate the current value
of an item, typically in the setting of a charitable
donation? (ie. how much an item may be worth at the
time it is donated to a legitimate charity), which
is often tax deductible. I doubt IRS would accept a
seller's estimate of? Fair Market Value for hobbyist
sale transactions as an accurate cost basis since
the item may have been purchased many years in the
past or inherited gratis,? and determining past
valuations is extremely difficult without records
(ie. original purchase invoice/receipt). Here is an
informative article on the subject of hobbyist tax
obligations in light of the new IRS regs (reducing
the annual sales level from $20K to 600K/annum).
Interestingly, it discusses how the IRS may take
action against you if you try to 'skirt' around the
new reg by using PayPal "Friends/Family" instead of
" PayPal merchandise" unless you can clearly
establish the transaction was really made between
friends/family members and not strangers. And it is
not only PayPal - other 3rd party payers, like Venmo
will be required to also issue 1099-K's for sale
transactions that exceed $600/annum. So seems like
the safest thing is to avoid all of these 3rd party
payers, and handle sale of vintage gear by accepting
payment in form of? check/MO/Zelle, at least for
now:

In general, the IRS will allow you to use ?"fair

Thus, with just a small amount of paperwork,
