Default Leak Tl/12+

Delighted to say, I rescued one from under a workbench in college today, has been kicked around for years. I think, all we need is to replace the valves (college has mounds of them), check the circuitry and off we go

Assuming you're serious (I can't tell whether you're kidding or not!), please take care. Look for signs of damage or burning and be prepared to replace components affected.

Be aware that there's a more than even chance that some capacitors, especially electrolytics, will not perform well. Some resistors can also have drifted out of spec. Electromechanical contacs (switchs, plugs and sockets, tube holders) may need cleaning. Transformer windings should be checked for continuity.

I'm sure other people can suggest plenty more cautions before assuming that it will work.

Much appreciated, I have more than enough access to caps/resistors etc, and had planned to replace the valve sockets anyhoo. The iron *seems* to be in good nick - will get down to analyzing it later

I've worked on a number of Leak amplifiers and you can be assured that most components will have drifted out of spec by this point in time, and I would not power it up at all without first replacing all of the electrolytics and coupling caps - I'd check all resistors as well at this point and replace any that are off.

Duly noted - I've access to almost every resistor and cap imaginable (college stores ), so I'll start after my own amp is complete.
