DanOwens Posted June 24, 2016 Share Posted June 24, 2016 (edited) I have a Hartke A35 that I put in storage for a while and on taking it out, discovered a fault. I sent it to an amp tech who said there's a fault on the board that wouldn't be worth fixing. So now I've got a nice enclosure, a nice speaker, but no 'head' section. I have a LM250 but I'm worried the little Hartke speaker won't take that level. Any suggestions on a solution? Any micro, low-watt heads around? Thanks!

machinehead Posted June 24, 2016 Share Posted June 24, 2016 Use the volume control and your ears. I'm sure that if you're careful the LM250 will work fine. Frank. Quote Link to comment Share on other sites More sharing options...

I found a tiny 30w TDA2030 power amp circuit on eBay which looked simple enough (and the size of a credit card) but when I started to look into how to power it I realised I have no bloody clue about all that and would probably end up crispy if I gave it a go!! Anyone done any TDA2030 amp builds? Dan Quote Link to comment Share on other sites More sharing options...

MoonBassAlpha Posted June 24, 2016 Share Posted June 24, 2016 (edited) There's some great dinky little amp modules on 41Hz, some of which can run off batteries. May need some kind of a preamp too though. Edited June 24, 2016 by MoonBassAlpha Quote Link to comment Share on other sites More sharing options...
