I have 5 of these plug in replacements diodes for the 866/3B28.  Two are 
in original wrapping that I have not disturbed.  I did open the outer 
covering to verify contents but not the inner wrapping.

The other three are loose and I checked them to be sure of their 
continuity.  All check good, with minor variations of conductivity 
through it.

$25 each plus shipping costs.

Also I have two Semtech SA 7477 which are rated at 10 KV at 4 Amps. Both 
check good.

$35 each plus shipping.

I have one 1N1237 and one 1N1239  The 37 is rated 1600 volts at 750 Ma. 
good for receivers,   the 39  is 2800 volt at 500 Ma.  date says it 
replace the 5R4.
$15 each plus shipping.

Any interest?
