[Heathkit] SBA-1400-4 power supply

[Tom Chesek]

Thanks for the reply.  From what I see I think the supply is almost 
identical to the Yaesu but I was hoping for a little more info than what 
Yaesu provides.  I have not yet asked Gary.  He has helped me out at lease 
twice in the last number of years and I hate to bother him if I don't have 
to.  I thought that there might be others like yourself with the info I 
need.  From time to time former techs from Heath jump in with comments and 
information.

Tom
