Handcrafted in the United Kingdom, the VA2A follows the blueprints for the legendary LA-2A Leveling Amplifier (rev. 1968).
Ever since its release, the LA-2A achieved wide acclaim in professional audio applications because its unique, optical attenuator allowed a smooth, unobtrusive compression/limiting action unlike anything previously invented. The VA2A is Valtech’s tribute to these original Teletronix units.
The VA2A is a 68’ LA-2A but it has several small improvement mods:
- Increased headroom to complement modern audio gear and studio practices
- Increased output frequency bandwidth with a Russian military-grade paper & oil output capacitor (the equivalent of the Mundorf Supreme Silver Gold Oil Capacitors)
- Audiophile-grade Polypropylene caps on C2 & C3 (SuperCap Hovland Series)
The Input Transformer is a Sowter 1449 - an exact modern clone of the UTC A-10 with a 1:9 ratio. In the original LA-2A this was the first point of amplification and was used to combat noise-floor in audio. Because of its extremely high input ratio the LA-2A provided enough gain to be used as a microphone preamplifier. Modern clones of the LA-2A often feature 1:3 - 1:4 input transformers, but to stay true to the original design the VA2A is equipped with a 1:9 ration input transformer. The output transformer is also a direct clone of the UTC A-24. These Sowters are the most accurate modern recreations of the originals and provide exceptional performance and tonality.
The valves (tubes) are all NOS RCA-s, as used in the original. This particular unit is equipped with one RCA 12AX7 Black Plate and one long Grey Plate. The "Black Plate" is the most important valve in the VA2A as it has the biggest impact on device tonality. During the 50s RCA made the first 12AX7 valves and the LA2As were being equipped with them. Those old "Black Plates" are characterised with low self-noise and exceptional mid-range response and are considered the "Rolls-Royce" of 12AX7 valves.
The Optical Cell is a Kenetek T4B.
The potentiometers are a custom replication of the original Allen & Bradley LA2A pots and feature the same custom audio taper. They are made by Blore Edwards - the current supplier for AMS Neve pots.
At Fuzz Audio, all vintage/NOS vacuum tubes purchased through our website are guaranteed for one year from purchase date. We accept returns for tubes going noisy, losing output/performance prematurely, and of course losing function all together. (Read about power tubes below).
We will not cover damage from red plating neglect, glass breakage of any kind, loose bases, or other obvious faults that are due to neglect, rough handling or egregious constant use.
This policy is meant to protect the buyer from having a tube go out on them prematurely from a flaw we missed. Tubes, especially preamp tubes, should last half a lifetime, and well beyond a year, so we want to guarantee each customer that you get a tube that will last.
For power tubes, although we will honor any faults mentioned above, we will not accept a return for a power tube that has obviously been used for 6+ hours a day for every day of the year for one year. Power tubes that have clearly been used beyond their normal wear point will not be accepted.
If you suspect one of your vintage Fuzz Audio tubes has gone bad within one year of purchasing, simply reach out via our chat or at Support@fuzzaudio.com and we will assist you in the warranty exchange process. No receipt is needed.
Please note, it is possible we will be out of stock of the tube that is in need of a swap. If this is the case, we will either offer a refund, credit, different tube, or send the first available tube of that type when it comes back in stock.
If you have any questions or concerns, please reach out!
