1) About the Dizzy 30 One of our most popular and versatile amplifiers, the Dizzy 30 was our response to one of the most sought after amplifiers in guitar history. Combining classic tones with modern features, the Dizzy 30 is a true benchmark in hand-wired, Class A tone.
2) QUICK SETUP (for instant gratification) 1) Plug your guitar using a 1/4” instrument cable into the input “1” in either the left (normal) or right (EF86) jack 2) Plug a suitable power cable from the DZ30’s rear panel AC MAINS cable inlet to your wall power receptacle 3) Plug the DZ30 into your speaker cabinet using 1/4”...
3) FRONT PANEL CONTROLS On the front panel of the Dizzy 30, you can see fourteen items of interest. From left to right: 1) INPUT 1 ¼” instrument jack (NORMAL channel) 2) INPUT 2 ¼” instrument jack (NORMAL channel) 3) VOLUME control (NORMAL channel)

INPUT 1 (NORMAL) is a normal gain input for the NORMAL channel of the DZ30. Use this input for great touch response, higher gain, and a classic feel. INPUT 2 (NORMAL) is a low gain input for the NORMAL channel of the DZ30. Use this input for increased headroom. VOLUME (NORMAL) adjusts the channel volume for the NORMAL channel.

DOWN position, the DZ30 is in standby mode. ON / OFF two-way toggle switch powers the Dizzy 30 on and off. With the toggle switch in the UP position, the DZ30 is ON. In the DOWN position, the DZ30 is OFF.
4) REAR PANEL CONTROLS On the rear panel of the Dizzy 30, you can see nine items of interest. 1) AC MAINS IEC cable inlet 2) FUSE 3A or 2A slow blow fuse 3) SPEAKER PHASE two-way toggle switch 4) LOUDSPEAKERS ¼” speaker jack 5) LOUDSPEAKERS ¼”...

SPEAKER PHASE reverses the phase output of the amplifier. Generally, use your DZ30 in the NORMAL position. This is most helpful when combining other amps with the Dizzy 30. If you notice your amps sound thin and hollow when running them together, they are probably out of phase.

(in this case, 8 Ohms). EFFECTS LOOP CH1 ¼” stereo instrument jack can be used to add effects to the NORMAL channel of the Dizzy 30. Because one stereo jack is used for the effects loop, we recommend a stereo plug (male) into a Y-cable mono jack (female) adapter.
5) TUBE COMPLIMENT The Dizzy 30 chassis has two rows of tubes. One row is near the front of the chassis, and the other is more near the rear of the chassis. The picture below shows the row of tubes near the front of the chassis. These are the preamp tubes.

The picture below better illustrates the rear row of tubes. These are part of the power amp. From LEFT to RIGHT V5 – EL84 / 6BQ5 V6 – EL84 / 6BQ5 V7 – EL84 / 6BQ5 V8 – EL84 / 6BQ5 V9 –...
- For best results, an effects loop interface like the C-lator or Klein-ulator could be used with the Dizzy 30 amplifier. These units prevent impedance mismatching, as well as provide the ability to pad down the volume sent to the effects units hence preventing any overloading.

- It is not necessary. Feel free to experiment with different tubes (of the same type) in your OTS, though! How do I bias my Dizzy 30? - You don’t need to! The design is cathode-biased, Class A. The amplifier sets the bias point of the power tubes, and there is no adjustable bias to worry about! ...

I’ve read that the components used in this type of amplifier are really important. What is inside my Dizzy 30? - We use a combination of parts custom-made for us to our specifications (power transformer, output transformer, choke, high-temperature / low-ESR electrolytic capacitors) and those used in the original amplifiers (1/2W carbon composition resistors).
