− | == Remarks ==
| |
− | * Improved version of the P100 stereo power amplifier with optimized layout and RF immunity.
| |
| | | |
− | * There are 2 variants of the P101 in protection class I | + | == Bemerkungen == |
− | ** Beginning of the 90s with country of manufacture "Made in England" on the backside
| + | * Verbesserte Version der P101 Stereoendstufe. Verbesserte HF Einstrahlfestigkeit |
− | ** Mid 90's without country of manufacture indication on the rear panel, where the following modifications were made.
| + | * Später auch als CE Version erhältlich mit Schutzklasse II Isolierung d.h. ohne 3. Erdanlschluß im Kaltgeräteanschluß |
− | *** Modified inner chassis with mechanically optimised transformer mountings | |
− | *** Toroidal transformer with double output windings connected in parallel. --> less mechanical transformer hum
| |
− | *** Reduced base current (bias current) of the output stage transistors approx. 65mA/140mV (old 95mA/210mV) --> less heating up
| |
− | *** pre-driver stage with modified temperature compensation
| |
− | *** modified RC element for compensation of the oscillation tendency
| |
− | ** The P101 Made in England can be converted to the new version by component modifications.
| |
| | | |
− | Later also available as CE version with protection class II insulation, i.e. without 3rd earth connection in the IEC connector.
