Need help because of the Scale guidance. In what order do I need to pass the thread. Feel free to send info via WhatsApp to 017637642870. and where can I get a replacement tension spring from. Thanks in Advance, Rainer

The 7bc37c5c52ce231c19f9842eb5b170ea is a Hi-Fi stereo control unit, the manufactured by REMA Stollberg and as the successor to the REMA Toccata was developed.
Compared to control units manufactured up to that time, it was distinguished by some innovations that increased the use value.
The tonica has a 4-band tuner for the wave ranges LW, MW, KW and VHF, which is common in the Hi-Fi class, although the three AM ranges have no special features.
The VHF tuner, whose input part is equipped with MOS field-effect transistors, is characterized by a very good large-signal strength.
It has a 75 ohm coaxial input and its reception range ranged up to 108 MHz for the first time with a control unit.
The station memory with 14 places was also new, which, in addition to the main scale, could be freely occupied with FM stations.
The programming was carried out with the spindle potentiometers located behind a flap (which has a small compartment for storing a memo for the storage space assignments) with the help of a twelve-part LED chain below the main scale.
It acts as a "wandering pointer" by either one or two LEDs and serves as a rough orientation for the storage space allocation.
The stored transmitters can be selected with smooth-running type keys, a small red LED indicates the currently activated storage space.
In addition to the transmitter memories - when the device is switched on, storage space 1 is automatically selected - a normal frequency scale is available, which is activated by touching the rotary knob.
A horizontal, square, red LED is provided as a scale pointer.
Furthermore, the tonica has a six-part LED chain as a field strength indicator, a three-part exact tuning indicator, as well as an automatically switching off and on computer AFC.
The preamplifier of the tonica has no special features.
Volume, bass, treble and balance, as well as the turn-off correct auditory volume control (linear) and the volume (level), which can be lowered by 15 dB, are regulated by means of 3 IS A 274 via DC voltages.
Furthermore, the device has diode inputs for TA, TB 1 and TB 2, whereby the TB 2 socket is attached to the front of the tonica.
The power amplifier is also designed according to the technical state of the art.
It is supplied with a balanced supply voltage, which is why no decoupling electrolytic capacitors are necessary.
As a special feature, two pairs of speakers could be connected to a DDR device for the first time.
They are selected via two switches and connected via the two protective relays of the power amplifiers.
The two loudspeaker pairs can be operated individually or together, whereby the output power is electronically limited during the operation of both pairs in order to avoid possible overloads of the power amplifier or the mains transformer in the then present 2 ohm load case.
Due to the switchability of the speakers, the two headphone jacks are not self-switching.
The visual design of the Tonica is modern, objective, independent and can be described as successful, although the plastic front panel certainly looks a bit cheap.
Despite the large number of buttons, there is still a certain structure and clarity.
The size of the tonica was chosen so that it could be combined in width and height with the components of other DDR Hi-Fi systems, but due to the size of the circuit, the device depth of 300 mm is slightly larger than that of component systems.
