SABA 455WK (455 WK)
Country:
Germany
Manufacturer/Brand:
SABA; Villingen
Year: 1938 / 1939
Type:
Broadcast receiver (Radio).
Im Gegensatz zu Radioempfängern für kommerzielle und/oder militärische Zwecke und den frühen Empfängern für Morsezwecke nennen wir hier Radio bzw. Rundfunkempfänger. Aber: Gemäss internationaler Sprachregelung führt der Radiokatalog Band 1 alle Empfänger mit aktiven Bauteilen als RADIO. Wir unterscheiden hier ebenfalls nicht, ob mit Röhren bestückt, hybrid, mit Transistoren oder/und ICs.Radio or Tuner

Principle
Superhet - normally without a preamplification stage (as far as known). Please use «To add informations to model» if you know more! Thanks.
Récepteur TSF superhétérodyne. Normalement sans préamplification de HF.
Superhet ohne Vorstufe.
Nicht immer war bei der Erfassung klar, ob der Empfänger eine Vorstufe aufweist oder nicht. Im Zweifelsfall kam das Gerät in diese Kategorie.Super-Heterodyne (Super in general); IF-Freq. 485 kHz
Tuned circuits
8 AM circuit(s);
Wave bands
LW, MW/BC and two SW (long-, medium- and short waves). GO, PO et 2 fois OC (grandes ondes, petites ondes et 2 fois ondes courtes).
LW, MW und 2 x KW.
Kann zwei unterteilte KW Bereiche bedeuten - z.B. 16-25 und 31-49m-Band oder durchgehend plus gespreiztes 49m-Band - selten aber auch einfach KW-Lupe (Spreizung mit separater Bedienung).Broadcast, Long Wave and 2 x Short Wave.
Power type and voltage
AC set plus voltage range.
/ = 2 different voltages
- = voltage from-to

Trafo ist nicht immer mit Primär- undSekundärwicklungen versehen. Dadurch kann das Chassis ein gefährlichesPotential führen.Alternating Current supply (AC) / 110; 125; 150; 220; 240 Volt
Loudspeaker/pwr.out
Electro magnetic dynamic loudspeaker (moving-coil principle by Rice-Kellog) with field excitation coil - mostly used as choke.
Haut parleur dynamique avec bobine d`excitation - plus souvent aussi utilisé pour le self.
Elektrodynamischer Lautsprecher mit Erregerspule für das Magnetfeld (Fremderregung), meist gleichzeitig als Siebglied dienend.Electro Magnetic Dynamic LS (moving-coil with field excitation coil)

Notes
Normally we don't put the maker into the model name and tell not to search inclusive maker name in the model name field. Here SABA 455WK instead of just 455WK or 455 WK stands as an example - just to give you this information.

Hallo
Kann mir jemand sagen, wie man die Abschirmbecher der Schwingkreise abbekommt,
einfach abziehen? Ich möchte dabei nichts kaputtmachen und frage deshalb lieber mal herum.
Mit bestem Dank und freundlichen Grüßen

Hallo,
ich such für meinen 455WK eine Rückwand ohne Netzstecker und einen Satz Original Knöpfe zu dem Gerät.Vielleicht hat ja noch jemand sowas auf Lager liegen?
Viele Grüsse aus dem Westerwald

All members interested in Saba early Superhets (and especially members who have a model 455WK OR a model S 455WK), I have manually typed in (using the German character keyboard) and translated the article described above.
The translated output (using the Babelfish software translator) is as follows:
WE LEADING FORWARD: SABA 455WK
Superhet - 8 circuits - 5 Tubes
Wave bands: 13.5 - 34, 30,-91, 200 - 600, 750 - 2000 m
IF - 485 kHz
As alternating current equipment available
Tube assembly: ECH11, EBF11, EFM11, EL11, AZ11
Power absorption: 55 Watts Connection for 2 loudspeakers: Impedance about 7000 ohms
Special characteristics: Two-stage entrance band filter; even a three-stage and two-stage IF band filter; Three-gang variable tuning capacitor
Range automatic controller (change of coupling with the 1st IF bandfilter), with tone quality automatic controller combined: Language - music switch: Volume control before the 1st NF stage
Three-fold decrease reconciliation, on mixer-, IF- and NF stage working co-ordination
Tuning indicator in form of a magic eye
Wood housing: Electro-dynamic loudspeaker
The use of steel tubes became as well known first only for alternating current receivers and for such over Rm. 285,00 and/or RM. 280.00 retail price approved, because it was not possible to produce from these new tubes in the first year so much that an indiscriminate assembly of the receivers would have been feasible. It would be however nothing wronger than that to want to conclude from the restriction of the steel tube price groups higher on the devices that this kind of tube would be applicable evenly only for the expensive receivers! In the opposite, straight for the receivers of low and middle price classes, will steel tubes the great importance attain, are nevertheless possible it with their assistance not to increase the achievement of these devices inconsiderably without for this higher expenditures would have to be made. An interesting example for this is the steel tubed Superhet Saba 455 WK, which niedrigst to permissible steel-tubed receiver price on the market was brought - the costs RM. 280,00, and which is anxious in addition to use the progressive technology steel-tubes fully. In the progression this receiver the standard super of the German market enspricht, i.e. it consists of the mixer, an intermediate frequency stage, the receipt electric rectifier, a NF preliminary stage and the output stage. At the entrance of the equipment zweikreisig it is band filters intended, in order to suppress disturbances by image frequencies. The selection means of the intermediate frequency amplifier are formed for band filters by dreikreiseg it and zweikreisig it, about which the first earns completely special attention: The second -- thus the middle -- circuit is used here for the bandwidth control, such that the position of its is changed at the same time to the coil first and that of the third circle. Beside its ground connection this adjustable circuit does not possess any connections outward; it can be trained consequently not only extraordinarily absorption-poor, but also all difficulties always resulting in from the inlets come themselves into abolishment. Band filter curves and bandwidth control are therefore from ideal form. Under supports becomes the bandwidth control by a bass/treble compensation, thus by a low-frequency working tone quality automatic controller, which represents circuit-moderately nothing different one, as a variable inverse feedback, which pre-amp tube between the anode of the output tube is arranged. With the help of this automatic controller one can raise the high or the bass tones after choice; the arrangement is thus superior to the usual bass/treble screen, with which the high tones are only cut off. To these means of the effect on the frequency band shown by the loud

Greetings Collectors and Restorers
During recent posts to forum thread Meine Kartei (id=36275), by Herr Denoth and Herr Boeder, and an item that I had also added, it was suggested that I post this request to determine if any member may have experienced similar events while attempting to repair and restore a Saba model S 455WK that is in excellent overall condition.
Herr Denoth and Herr Boeder (and Mr Ernest Erb) discussed several items - one of which listed the merits of having an individual member's collection of models made available for on-line search by other members for various reasons. Very good supporting points were made to allow for this procedure. In this specific instance, I have begun a very slow search by reviewing the collections that are available to see if I am able to more easily determine who may have a "functional" model Saba S 455 WK radio to contact directly for repair assistance or for other specific data??
Would the existing software programs allow an individual member to make his collection data available to the entire membership (at his option), and with some specific items restricted - if he desires? At this time, I must review each/every member's collection data to see if he has the specific model that I am interested in.
Presently, I have detected several items that do not agree between the schematic and the actual radio. Additionally, many of the capacitors have no rating data on them . . .only what appears to be model number/item number stamped on them.
I have seen very little technical information on the forums that relate to the early receivers with the variable bandwidth circuitry.
Mit freundlichen Grüßen,
Respectfully,
Robert
