[Heathkit] MFC6030 replacement for SB-104

Fri Jul 13 17:21:44 EDT 2012

Hi Bruce,

Your question has prompted me to think about this and I think I have a simple 
solution. I have a "B" card with two missing regulators that I can try it on (I 
sacrificed them to make another copule of B cards work). If It works I might be 
able to put a kit together.

Bill

I am on the hunt for a 3-pronged power cord for the SB-303/SB-313.  Does anybody 
have one surplus to their needs, or can someone direct me to a commercial 
source?  I have temporarily rigged a 2-conductor cord with female Molex pins and 
shrink tubing, but this scares me. Thanks  Jack

Jack,

There is no commercial source.  In the day, they were used on some old
Friedan calculators and other devices.  There is a H-P cord that looks
similar but the pin spacing is wrong.  Trust me, been there done that.  See
if you have any old time typewriter/adding machine companies in your area.
I managed to find several from a company here locally.  They were packed
away in a storage building and were dirty, dirty, dirty.  Some can be made
but it would take several thousand dollars to pay the bill.

Happy hunting.

Hi All,

Has there been a logical solution to replacing the MFC6030 IC in the SB104?

I need one, my 11v supply has gone bad.

Google it and it comes up, but not a friendly source anywhere reasonable.

OK so maybe a "B" board for sale?

Thanks Bruce 73
