  • Anotaciones
  • Battery operated portable television receiver. Channels 2 thru 13 VHF. Sams photofact set 475 folder 2 date 2-60 features the Philco models H2010BL and Safari H2010L as the same schematic.

    There are four variants of the Philco Safari:  Model H2010L is brown leather and model H2010BL is black leather.  For each model number, there is an early version which corresponds to the 1959 schematic in the Philco Service Manual PR-3324 (this schematic was also published in the Sams supplemental folder 26S in set 460 in 1959) and the normal version, as documented in Sams set 475 folder 2 in 1960.  The differences between the early and normal versions include elimination of the sound take-off transformer in the normal version as well as some changes in transistor types used.

Report on electrical restoration of two different Philco H2010 Safari portable TV sets:

The first unit had excessive brightness, which was traced to an open CRT cathode bias resistor (R45 on SAMS schematic, 2.2 megohms which pulls the cathode positive in normal operation).

The second unit had only sound; the horizontal sweep was dead.  Since this TV (like many modern TVs) uses the horizontal sweep to generate B+ voltage for many of its circuits, loss of horizontal sweep renders many functions dead.  The problem was traced to an open winding on the horizontal oscillator transformer (L19 on SAMS schematic).  This transformer is located right next to the tuner assembly, and either mechanical shock or stresses during removal of a PC board during service can put a lot of mechanical stress on the transformer, bending or breaking its mounting assembly.  I was able to repair this transformer by finding the broken wires and resoldering under a microscope.

On both sets, all of the original semiconductors and tubes remain functional.  All of the many original electrolytic capacitors are also still good (conversations with others who have restored this set confirm that this is a common experience for this specific model).
