I mounted one for my Watchman TV (actually 6V) into Can you provide part numbers and makers? When I was investigating a power supply for my 9V electric guitar effects, I could only find 12, 8, and 5 Volt regulators in the TI book. I know there are "adjustable" ones, but I operate on the KISS principle when it comes to circuits! I'm trying to get 9V from a really dirty 12V wall-type transformer, and ended up with a 12V regulator chip, and thus the very problem that is the subject of this thread. Why do they only seem to make those screwy values when all my DC items are 3, 6, and 9 volts??? Thanks for the circuit, anyway. -- Jim Dunne Motorola Inc. uunet!motcid!dunne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Things are more like they are now than they ever were before. - Eisenhower
