Brazilian Sets

PAL M

Brazil is unique in being the only country to use the PAL M colour standard.  PAL is used in conjunction with the 525 line, 59.94 field/s system M, using (very nearly) the NTSC colour sub-carrier frequency.  The exact colour sub-carrier frequency of PAL-M is 3.575611 MHz.

PAL-M signals are identical to North American NTSC signals, except for the encoding of the colour carrier. Therefore PAL-M will display in monochrome with sound on an NTSC set and vice versa.

PAL-M is incompatible with 625-line based versions of PAL, because its frame rate, scan line, colour sub-carrier and sound carrier specifications are different. It will therefore usually give a rolling and/or squashed monochrome picture with no sound on a native European PAL television, as do NTSC signals.

PAL-M being a standard unique to one country, the need of to convert it to/from other standards often arises.

  • Conversion to/from NTSC is easy, as only the colour carrier needs to be changed. Frame rate and scan lines can remain untouched.
  • Conversion to/from PAL/625 lines/25 frame/s and SECAM/625/25 signals involves changing the frame rates as well as the scan lines. This is achieved using complicated circuitry involving a digital frame store, the same method used for converting between NTSC and the 625/25 standards. The fact that the colour encoding of PAL-M and PAL/625/25 is the same does not help, as the entire signal goes through an A/D-D/A conversion process anyway.

Philips Brazil

My sincere thanks goes to Luiz who has supplied this very rare information on Philips sets made for the Brazilian market.  Luiz advised that:

“Color broadcasts began in March 1972 as required by the dictatorial government of the time, which threatened to hunt concessions from broadcasters that do not produce a quota minimal of color programming.

The first color TV sets were very very expensive, talking to a friend who lived at that time, I learned that the first Philips color TV (R26K191) costs the price of a semi-new Volkswagen, and console-mounted model (R26K197), the price of a new Volkswagen, stating that both televisions are not equipped with remote control, or any other refinement, so they are very basic, this absurdly high cost is due to the fact that most of the components used in these devices were imported, as were specific components for exclusive use in color TV sets, and our dictatorial government imposed import taxes of 80% of the declared value with the intention (official version) to strengthen the national industry, still had waiting queue because the production did not follow the demand.

In the biennium 1973/74 began to implement the national production of these components, which cheapened enough devices, but these were still unaffordable for the majority population, because this, in 1980 the majority of TV sets in the country were still in black and white.

In 1972 have been only produced color TVs of 26 ‘, but in 1973 were launched models of 22’, 20 ‘, 17′, and 16′ (Philips launched sets of 22′ in 1973, and one model of 18’ in 1978, the R18K212) all of these sets were equipped with delta 90° CRTs.”

The Models

The set below is the Philips R26K192 (1976 ad.) produced in Brazil between 1973/77
Model number: R26K192
Chassis Type: KL-1
CRT: A66-122X 26 inch, delta 90°
Comments: Push button 7 VHF channels selection, 127V or 220V version, 10 tubes, power consumption 220W, color killer and music/speech switches. TV Philips R26K192

The model in the shades is not too bad either!!!

Note from Maarten:

“Very interesting chassis, the KL1. A schematic can be found at Elektrotanya. It seems to be a simplified and further developed version of the K7 chassis, also it seems to be a (mostly?) Dutch development, judging from the 3122 12NCs (Brazil design staff would have used 3106 12NCs). An earlier start of the Philips Global Range (avant la lettre even) than I had suspected, even though I had wondered before why there was a mention of NTSC on the silk screen of a K7 convergence board.

In later years, Brazil must have had some design staff but designs in the 1980’s and 1990’s were based on the Global Range of chassis of which only some GR1 and GR2 variants were intended for Europe.”
