Hi
For a while now I've had a pair of Stax Lambdas (brilliant!) with an SRD7-SB Energiser box that was designed to take the output from a power amp and switch it between speakers and 'phones (earspeakers!). I have acquired a venerable old Moth 30 power amp (a pretty decent Stan Curtis design I believe) to drive them independently of the main system and subsequently decided to have a go at putting the electronics of both into one casing - thus getting rid of all the dodgy wiring/switching in the Stax box and hooking them up directly together to create a single dedicated driver unit for the 'phones. Pix are attached - it sounds absolutely brilliant! Am considering going in to production on this with an improved version of the amp and an emulation of the original Stax SRD7-SB circuitry (with possible enhancement to Pro Bias output option and also one that takes a full line out with Volume control). Is anyone interested? Am talking to a prominent (no names, no drill) electronics engineer friend who reckons he can replicate the whole with significant tweaks ( and also make it universal for 'normal' can users and I've already got the chassis/casing sorted...no idea on price etc. but it might be worth a punt for serious can fans...
