HP-33E POWER SUPPLY BOARD
Message #1 Posted by jia on 2 Jan 2003, 12:58 p.m.

I have got an old HP-33E which doesn´t work as result of a problem in the power supply board.

I think a transistor is failing (there are four), but it is hard to get a replacement for these components.

May be somebody knows which transistor I can use.

Thanks in advance

Jon
