Hazelrigg Industries DVA
(B-Stock)
The DVA is a hybrid microphone preamplifier based on the Hazelrigg Industries VLC and DW Fearn VT-2 preamp. Utilising a single 6072a vacuum tube, the input circuitry matches the VLC/VT-2 input stage exactly and features transformers in both the input and output stages.
Make-up gain is provided by a low-THD/high output solid state signal path (as opposed to the vacuum tube circuits in the VLC/VT-2) due to the module size and power supply limitations inherent in the 500 series format. Total gain available is approximately 60db.

B-Stock Gear FAQs
What does B-Stock mean?
In the UK you can only sell items as New if they are in their unopened, original packaging. But what happens to the items that may have been sold and returned within the purchase cool off period? They can’t be sold as new anymore because the box has been opened. It’s not new, but it’s also not second-hand, so it is then classed as B-Stock and typically priced somewhere in between. The same also applies for items that might have been scratched or dented in the manufacturing process or during delivery.
All of our B-Stock items are sold on behalf of our manufacturing partners and are under 3 month Make Noise Pro Audio warranty and in certain circumstances the original manufacturers warranty too.
All units will have been either fully tested by us in-house or a factory QC by the manufacturer where appropriate.

B-stock units are usually in "as new" condition. You get the reassurance of being a relatively unused product with the lower cost vs buying new.
