Wurlitzer 200 Amplifier Rebuild Kit

Wurlitzer 200 Amplifier Rebuild Kit

from 22.00

This kit contains hand-selected replacements for components that commonly fail in Wurlitzer 200 electronic piano amplifiers. Installing the parts in this kit can help you achieve a more reliable, cleaner-sounding Wurlitzer. Note that Wurlitzer 200 components cannot be installed in a Wurlitzer 200a. If you have a Wurlitzer 200a, check out the Wurlitzer 200a Rebuild Kit here.

The Basic kit includes:

  • All electrolytic capacitors

  • Power supply resistors

  • Selected input components

  • Selected preamp transistors

The remaining transistors, capacitors and resistors can optionally be added. Use the drop-down menus to select the components that you would like included in your kit.

Over time, components in vintage amps will degrade, resulting in noise and poor performance. This kit contains hand-selected replacements for components that commonly fail in Wurlitzer 200 amplifiers. Installing the parts in this kit can help you achieve a more reliable, cleaner-sounding Wurlitzer.

Note that the Wurlitzer 200 is very different from the Wurlitzer 200a. If you have a Wurlitzer 200a, you must purchase the 200a kit here.

Choosing which components to replace and which components to keep depends on a number of factors, including the condition of the amplifier as well as the personal preference of its user. For this reason, we offer several kit options that will allow you to replace as many or as few components as your specific amp requires.

Features of this kit include:

  • High-quality components hand-picked for suitability in a vintage solid state circuit

  • Components individually bagged and labeled

  • Can be installed in all Wurlitzer 200 amplifiers

Warning: Safe and effective installation of the components in this kit requires some electronics experience. Incorrect installation of these components can result in damage to your amplifier or injury to yourself. If you are unsure how to install these components yourself, you can mail in your amp or drop it off at our Tuckahoe, NY location and we will install the components for you.


The Basic kit includes all of the electrolytic capacitors, all power resistors, and a small selection of critical preamp components. This kit will improve the reliability and performance of your Wurlitzer with a minimum of replacement components. It includes:

  • All filter capacitors

  • All electrolytic coupling capacitors

  • All high-wattage resistors, including output transistor bias resistors

  • Three transistors that may be used for TR1, TR2, TR3, TR5 or TR6

  • One polypropylene input coupling capacitor

  • Selected input resistors


Why replace these components?

  • Electrolytic capacitors deteriorate over time, which can cause hum, poor frequency response, or otherwise reduced performance. Note that although new electrolytics can improve the noise floor of your amplifier, they are not a magic bullet. There are many factors that can introduce hum into a vintage circuit. However, even if the electrolytics are not the primary cause of your Wurlitzer’s hum, it is always worthwhile to replace them for the overall health and longevity of your amplifier.

  • High-wattage resistors perform under conditions of high heat and stress that, over time, can cause their values to drift. In the Wurlitzer 200, high-wattage resistors set the bias of the output transistors and are very important to the amplifier’s sound quality. Deteriorated resistors can also introduce noise into circuits. We recommend replacing these resistors at the same time as the electrolytic capacitors.

  • The coupling capacitor and input resistors are intended for your amplifier’s input circuit. Although components at an amplifier’s input are no more likely to deteriorate than components elsewhere in the circuit, the input is very sensitive. Noise and poor frequency characteristics at the input will be amplifier by the rest of the circuit. For that reason, we prefer to replace input components in many amplifiers that we repair. We have included them in the Basic kit so that you will have that option as well.



You can also select one or more optional add-on kits. For further details, check out our guide: What components should I replace in my vintage amp, and why?

  • All transistors. Select “Basic Kit with Transistors” to purchase this option. This option includes everything in the Basic kit, but instead of including just three preamp transistors, we will include all of the transistors in the amplifier, including output transistors.

  • All capacitors. This option includes new polypropylene replacements for all remaining capacitors. These capacitors are low-noise and excellent for audio applications. The remaining capacitors in the Wurlitzer 200 perform various roles, and deteriorated capacitors in this circuit can cause a range of problems. By having all of the capacitors on hand, you will be able to replace as many or as few as your particular Wurlitzer requires.

  • All resistors. This option includes a complete set of resistors for the Wurlitzer 200 amplifier. The small-wattage resistors in this kit are high-quality, low-noise metal film resistors. If your Wurlitzer happens to have one or more noisy or damaged preamp resistors, this kit will have you covered.
