[time-nuts] LPRO-101 internals

[Mark Sims]

Q703 voltages look good (with cover off and unit working).  Lamp color seems good (slightly pinkish violet).  The room that I am in is lit by DC halogen lamps so not rippley light to worry about.

I think I'll try soldering a wire to Q703 and try measuring it with the case on...

Another thing to try is to box in just the lamp assembly and see if heat buildup in the lamp box is a problem or if it is heat in the rest of the circuitry.  The LPRO cover has an internal box that goes around the lamp assembly.  I suspect that it would be heat in the lamp box...  but it is pretty striking how much cooler the whole unit runs without the cover on...  too bad the cover is also part of the magnetic shielding.
