looking for IC: MC790P (Heath p/n 443-9)

[Alex [Temple-Heath List]]

Hi all,

Today I spend the better part of the day cleaning and restoring a Heathkit 
IG-28 color bar generator. It is now all nice and clean, but I found it has 
one bad dual JK flip-flop chip in the signal divider chain that has a Q 
output pin that does not follow the input signal, so I need to replace it. 
The IC is a Motorola RTL family chip, MC790P or Heath p/n 443-9.

Already did a google search and only came up with lots of obsolete parts 
vendors that either want to charge outrageous prices, or have a huge 
minimum order.

I was hoping that maybe someone would have a spare they would be willing to 
sell me. May even take 2 or 3 as extra spares if the price is right.

Thanks in advance.
