Lavoie LA-265A

Electrical difference to 545

The high-voltage circuit is identical to that of the Tektronix 545A. Glow lamps are used to stabilize the high voltage in brightness circuit. However, the glow lamp stabilizer is often faulty. The lamps aged too fast, with the result that the trace flickers.

Mechanically difference to 545

Transformer is potted. The ceramic terminals may be soldered with ordinarily solder because the terminals have tin-plated steel inserts.
