Re: AVI Lab Series Modifications (less is more)

Thanks _D_S_J_R_. I've been toying with building Pass stuff for years, never got round to it. I think I'm getting to the stage where learning fun isn't fun any more. I've re-worked a lot of stuff over the years, probably all the wrong stuff but I had fun. I still have my class D and KT88 amps and it...

Re: AVI Lab Series Modifications (less is more)

All I want to say is that AVI's designer is one of the few electronics design engineers who I feel would only put in what was needed for good stable working and I don't remember his amp or digital designs being full of ignorant bullshit as so many domestic designs are. I remember he progressively s...

Re: New DAC

You need the power supply, your wall mount supply is useless. Has anyone tried a battery pack with one of Docs Dacs? Thinking about maybe an external power pack / phone charger something like this maybe? https://www.ebay.co.uk/itm/External-10000mAh-Power-Bank-Pack-Portable-USB-Battery-Charger-For-M...

Re: AVI Lab Series Modifications (less is more)

Try the AVI with out inductor again with the LS5 arrives. Squealing does indeed sound like oscillation to me. My avondale power amps are running absolutely fine without input coupling cap, zobel and output inductor. Inductor damping resistor bypassed as well I've asked Doc to hold off on the LS5, I...

First sound was hum, (found to be caused by me forgetting the signal return between the amp and volume control Doh!) Then the squeeling started, now ive never heard oscil...

Re: New DAC

I'm sorry, I'm dumb for electronics, except "don't touch the little piggy's nose in the wall". I've checked the links, the psu is 9v, the dac is 5v, is this ok? Ive run a 5v DAC from a 9v power supply and it got a little hot, theres one 5v version left but its not exactly the same type of...

Re: New DAC
