diyAB Amp - The "Honey Badger"

[AndrewT]

I would not recommend 340/350 as substitutes for 1381/3503
The only parameter they have in common is 300Vceo.

D1 & D2 are not 1n914 @ 1A as stated in the BOM. These should preferably be rectifier diodes, 1n4001 or similar.
1n914 are signal diodes.

Andrew thanks.
If I build this amp I would use 500VA transformers for each channel and large heat sinks. So the power supply should not be an issue. I would like the amp to be able to drive 4ohm or less drivers and hence my question of using 4 pairs on the output.

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

Unless you have a built in scope in your ears.

Thankyou very much Sir, yes i see clearly picture of VBe prototype using mje and i think big vavas and ccs using this too. I will build using toshiba TR for driver and final.

Just remember to be careful sourcing those toshiba for I read reports of counterfeit toshiba parts.

Sir, Thank you very much for your attention. I'll carefully sourcing those toshiba TR.

Hiii all...
Can any body tell me about the sound quality of this amplifier.. ? I plan to built the stereo amp that have very good in sound..
can we compare with the Sr 200..? wich is the better sound? thanks..

@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

Any news on the parts pack?

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!!
