On the Wa2a we offer a wonderful circuit upgrade that CULLS its namesake and really brings our the Urei.

We put a lot of love into the mods on this one as with all of our modifications, to squeeze out the maximum performance possible.

While the design is not authentic to an original this one is very close but with some cost cutting measures that small up the sound when compared to an original.

With the modifications they sound great on Bass, vocals, room mics and more and are a lot closer to the original.

Pretty much anywhere you would want to put a LA2A, like vocals and Bass


This design is fairly close to the original and uses Cinemag transformers and a slightly different Tube configuration as well as a Buck Boost system for the main power supply voltages.

As a result of the cost cutting measures it sounds clean but also sounds very small when compared to an original LA2A and lack some of the character and warmth you have come to expect when you hear the name LA2A.

Our modifications fix all of the issues and bring back the low end, smooth out the compression and bring back the character to the design.

So The modifications:

We do a complete audio path upgrade using premium parts for lower noise and higher headroom as well as lower distortion.

All Audio caps are swapped out for better performance using Panasonic Parts and Orange Drop Capacitors in the audio path for more authenticity.

Bypassing is performed where necessary for lower noise in the power supply.

Power supply modifications are also performed Thru out for the lowest possible noise figures in the overall design and better current delivery.

Tubes are then swapped for more complimentary versions in the design in terms of authenticity.

The Results:

The service increases the headroom of the unit, widens the frequency response and increases the character/color of the design.
