These 10K resistors are a lower than usual value for a tube amplifier. This value

7、 was chosen for two reasons. 10K is smaller than 33K or 68K, therefore the amplifier will produce less noise at high volume settings. Secondly, when linking two or more amplifiers a common trick is to plug the guitar into Input 1 and use Input 2 as the output to the next amplifier. With 68K resistor

8、s, 1/10th of the signal is lost with each link. After the input resistors, the signal is split and fed to V1A and V2A. V1A serves as a preamp for the Reverb Drive, or Dwell control. The Dwell control feeds V3, a small power tube which drives the Reverb. V2A is a Cathode-Follower circuit which create

9、s a low impedance, isolated (from the input) signal to drive the Mix control (R2). V2B amplifies the Reverb return (sense) signal and sends it to the Tone control (R3). High frequencies are sent (shunted) to ground via C17. Varying R3 will move the wiper closer to or further from C17, thus making th

10、e Reverb brighter (Clockwise) or duller (Counterclockwise). The Reverb signal then sums with the Dry signal at the Mix control (R2). After the Mix control, the signal travels to the Send jack (J3) of the Effects Loop. The signal is then Normaled to the Return jack (J4) and drives V4A. This configura

11、tion allows the Reverb functions of the Vibro King to be sent out to other amplifiers (via the Send jack). It also enables a player to insert a delay unit between the reverb and the amplifier for a Rock-A-Billy type effect. A Volume pedal can also be inserted to control the Guitar and the Reverb. Th

12、e V4A circuit contains the Fat switch (S1). The Fat switch connects C4 to ground to provide a 3dB increase in gain, mostly in the low and mid frequencies. R17 is there to prevent “popping” of the Fat switch when actuated. NOTE: the Fat switch may pop the first time it is switched. This is due to the

13、 warm- up/stabilization cycle of the tube. The Volume control R4A is linked to R4B. R4B reduces the gain of the Reverb at high volume levels. This allows adjustment of the Volume without readjusting the Reverb Mix control. From the Volume control (R4A), the signal is fed to V4B, the Tone control dri

14、ver section. The signal leaves the tone controls through the Treble control (R5), and is fed to the Vibrato and Phase Inverter circuits. V6B is a low frequency oscillator. The Speed control (R8) varies the oscillation frequency. V6A is the Neon Lamp driver. The lamp flashes faster or slower based on

15、 the position of the Speed control (R8). The brightness of the neon bulb is sensed by two LDRs (Light Dependent Resistors) in parallel. The resistors connect to the Intensity control (R9) which varies the amount of attenuation. Because the Vibrato circuit connects to the amplifier directly after the

16、 Treble control, the high frequencies will attenuate before the bass frequencies. This simulates a rotating speaker effect. (TROUBLESHOOTING TIP: If the Vibrato does not function, first check the footswitch jack. The switching part of the jack serves to short one side of R57 to ground. If R57 is not

17、 grounded, the Vibrato will not operate. If the Vibrato exhibits a clicking sound, the problem is caused by the position of the neon bulb in relation to the LDRs. Adjust the bulb by gently pulling on the leads. Test and repeat as necessary.) 收音机爱好者资料库 Ra d i o Fa n s .CN VIBRO-KING THEORY OF OPERATI

18、ON (CONT) The signal then feeds the Phase Inverter (V5), which is a classic style split-load type, used without feedback. The output tubes (5881/6L6WGC) are arranged in a push-pull configuration that will produce sixty (60) watts into two (2). BIAS PROCEDURE: The bias, measured at pin 5 of V7 or V8

19、should be set to 46Vdc. However, the Bias need not be measured to be accurately set. To set the Bias without removing the chassis, set the Volume knob between 1-1/2 to 2. (The Bias control is located on the under side of the chassis, next to the power cable.) Adjust the Bias so the amp produces the

20、maximum Hiss. Strum a full chord and let ring. Now, turn the Bias control back just to the point that the sound of the guitar loses warmth and sustain. Then increase it slightly. This will ensure minimum crossover distortion and the best sound. PARTS LIST PRINTED CIRCUIT BOARD ASSEMBLY QTY PART # DE
