[R-390] Audio Deck Capacitor

[chuck.rippel at cox.net]

Good on finding the exact value.

In absence of that, an axial, 10UFD electrolytic @ 50V works just fine.

BTW, Tisha, I have an E-Mail in my "DRAFTS" folder for you as a reply. 
Have been 2-blocked and have not had the chance to finish it.  Have not 
forgotten you.

I found a perfect replacement capacitor for the sometimes leaking and
corrosive C609 8 uFd, 30 volt tantalum cap on the bottom of the audio 
deck.
On eBay there is a seller who has the next version of the 8 uFd cap but 
at
a 35 volt rating. This is not a liquid filled tantalum but one of the 
solid
bodied, later versions. Just do a search on Kemet Tantalum axial 8uF. 
They
are being sold in lots of 10 for $4.99 per pack.

Auction;  230807410986

I have used Kemet tantalum caps before on some circuit design work 
before
back in the 80's and 90's. They are very good caps. A few times I had 
caps
fail due to transients (lightning) and they crack apart, release stinky
smoke but no acid residue. The ones for sale right now are rated at 35
volts where the originals in the receiver were rated at 30 volts.

Tantalum caps are usually not available in voltages much past 100-200
volts. The design of the capacitor is fairly unique and does not adapt 
well
to higher voltage applications. These caps are about the size of a 1 
watt
resistor.

On the auction the "5 sold" were to me (I have 50 of these little caps). 
I
will keep them in my bottomless purse so if I meet any of y'all at a
hamfest I will give you a couple. My friend Perry will get a bunch when 
I
meet him up for the Tullahoma TN hamfest in a few weeks.

I have no idea how many the seller has available. I have no relationship
with this person. Hopefully they have thousands!
