The other prototype uses mje340/350 types, no problem at all.

Unless you have a built in scope in your ears.

@jofual: All i know, ostripper designer of this amp. Put all the best of his expreince to this amp. I'm not built it yet. But i bet this is a very good amp. Try to read thread of frugalamp and mongrel and you know who was ostripper. I've built sysmasym v5.3 and this amp derived from. Ostripper supersym ii aka mongrel. if you want to build it i think we can share expreince in our local forum

Default Operating voltage. . . can I use less than 60v rails?

Hey, I was wondering if I could use 35vdc rails in case I happened to have 2 way speakers and didn't need to crack up the vocals coming from the madly shaking woofer (aka didn't quite need the 150 watts when 60 would do) or in case I have 4 ohm speakers that need good current but didn't quite need as much voltage, then could I use 42vdc rails?

I guess I just need a briefing on what rail voltages work well for this amp. Is it specific to 60vdc rails or can I use less without getting into a lot of modifications?

Thanks!!

Hi,

OS's post #171 diyAB Amp - The "Honey Badger" would suggest that the amplifier would work with 15VDC rails, certainly fine at +/- 42V. But would you need all of the output pairs for that supply voltage?

A). Thank you very much! Perhaps there's some common transformers usable that we may already own.

B). In some case the 60vdc rails doesn't need the triple parallel output and there are other cases where the 42vdc rails needs triple parallel outputs and sturdy devices. That seems to vary by speaker load, right?
