Kenetek ART Pro VLA II Input Transformer Mod Instructions
[ART-PRO-VLA-II-MODS]

Thanks again for the Pro VLA Mod !!! I tried to get the WF30s but got out bid!! I went with some vintage UTC A 21s instead and they sound awesome! nice full sound out of the VLA now...I can cut back on the compression part of the circuit and let the transformers do what they do best! Now I'm not afraid to deliver some serious audio to this unit ...it definitely holds up!
The info and directions were great and to the point!
