Linn Drum Power Supply rebuild

Linn Drum Power Supply rebuild

2010-03-24 by cpt.zilog

Hi. First post here... great forum !

I would like to know if someone would have a spare in order to finalize my Linn's PSU rebuild.

The part I'm looking for is very hard to find. It's a Lambda voltage regulator, and its reference is:

LAS6330A / in a TO-3 steel package

If anyone has one, please let me know!

Thanks and best,
Vincent.

Hello,
  Instead of tracking down a 1980's electronic part for a power supply, consider just using an inexpensive surplus PC power supply.  For $5 I got a used Dell 250Watt supply that has no trouble putting out 3A at +5V along with several amps at +12V, -12V, and +3.3V.  I believe that you can add the voltages together (for example: Gnd -> +5V +++ Gnd > +3.3V ==> +8.3 volts) because each branch output of the power supply is isolated from the other branches.
  An old PC power supply is a cheap way to get a high current regulated power supply if you only need +5V, +12V, -12V.  Most newer supplies have high current regulated (>5Amps) of 3.3V along with -5V.  Usually they require a minimum load on the +5Volts of about 1/2 amp, but the surplus Dell supply that I bought doesn't need a minimum load.

This company bought Lambda quite a few yrs back
