Soooooo.... anyhow my ehha is in pieces. But my 4 channel space heater is up and running, waiting on the other 2 channels for the ehha, no idea when those will come. I am considering adapting the ehha for speaker use, but I probably won't as I would have to get creative with my heatsinking. I got my little 9v toroidals in but my little lm317 regulator may be ill equipped for the job. I'll give it a shot though when my new case comes in early next week. I suppose I could try it as is now since the tube filament current should be constant anyhow (just doubled soon). I have it screwed to the back panel of the current box that now houses a b22 but it's like a giant aluminum heatsink anyhow... Will see how hot it gets . I have parts coming in for an lt1084 regulator that will be slightly bigger than my lm317 regulator but better equipped to handle a constant 1.32a I think... Hopefully I can find a good way to mount it inside the amp case. Shouldn't be too hard... the b22s are really squished into the case and that seems to run far hotter than my ehha ever did. I am seriously considering practically cutting out almost all of the top panel and attaching a metal screen of some sort there...
That said I haven't really done any work on the psu case besides filing out the hole for the iec plug a bit. I could get a bigger case to accommodate off board heat sinks and use the case I was gonna use for the ehha to house multiple S22s and go ahead with the speaker amp :O. Ahhh decisions
