Vox ac30 serial dating
These are my pages dedicated to the wonderful classic valve guitar amps known as HIWATTs - the product of the design genius of the late Dave Reeves.Dave Reeves worked at Mullard during the day, but in the evenings he worked in a tiny shop in Kingston, where he repaired hifi sets and televisions as well as musical instrument amplifiers.It was here he conceived the idea for a unique, sturdy and reliable line of amplifiers.Here Reeves started creating his Hiwatt designs, which were never just "me too" copies of existing popular amps, but completely original and different.However, the EL34-powered AC30 was short lived, and a new AC30 version appeared in late 1959.This second generation AC30/4 had two channels with two inputs, hence the "4" in the model name, and a single tone control, and was powered by a quartet of EL84 (6BQ5) power tubes, making it truly a doubling of the AC15 power amp circuit.The GZ34 rectifier tube was eliminated, and the cabinet was made of particle board.All one can say is that these cost saving measures probably saved the AC-30 from extinction.
Also included is a month-by-month chart for dating A. 7) A full Vox chronology and a full listing of JMI employees is included, along with source materials.These amplifiers used only the highest quality components inside and out, featuring transformers by Partridge and valves by Mullard from the beginning.While doing all this, he produced an OEM run of amplifiers for Sound City, and was laid off by Mullard.The circuitry on this Rose Morris produced version of the AC-30 was mounted on a single printed circuit board that was easily warped by the heat generated by the amp.The original preamp gain structure was attenuated by a new circuit design that limited output.
To many, the most celebrated AC-30 was the top boosted 1964 model manufactured by Vox under the original JMI ownership.
