Just a bit of an update. I believe the cost has come out at around £350, in a smart aluminium box. I’ve now heard the finished article and, compared to mine in a steel box Steve had lying around, the new one offers further improvements in energy and natural dynamics, tunefulness and timing. I’m getting mine rebuilt into an aluminium box as we speak. Steve has finished a handful of these and I believe they are on their way to those customers. I hope these folk will share their impressions on here, once they’ve installed them.
