Re: The Search For Audio Tranquility.

Reading that, it seems to be a lot of R Dunn like talk about the "music" without really defining what that means, and then it wanders down a set of suggestions that ends up looking very much like the Audio Note product line. I think it means different things to different people. Some are into the g...

Re: The Search For Audio Tranquility.

Like that article. The room speaker person interface is the thing most people will hear when they visit and the rest is the cherry on top ... mostly. Was discussing this very thing with another DIYer in the last few days. Although I'm a tinkerer, I've only owned 2 speakers and 2 amplifiers in 40 yea...

Re: New SE With Triode Mode KT120/150

But ‘slugging’ the music comes into my head again with large caps. I have been thinking about this and feel I have to post an opinion on it before it becomes dogma. etc No one ever said this was simple. (Or if they did they were wrong) I'm with this thinking too and that was a good explanation. It ...

Re: New SE With Triode Mode KT120/150

I like choke input coz it keeps things nice and smooth in that the current isn't delivered in big pulses like cap input. You can see that in PSUD by looking at the current through the diodes. But some folk prefer cap input but don't ask me why.

Re: New SE With Triode Mode KT120/150

Looks like you have your answers. Doesn't hum, sounds good, job done. Must have missed the hum bit hence your fiddling. We all have our preferences. Mine is not for resistance in the power supply unless I need to decouple. But then I have iron everywhere and it all weighs a ton. Pros and cons. And I...

Re: New SE With Triode Mode KT120/150

Well personally I wouldn't want 300R in series in a power supply. I imagine the 320H might not do much for ripple but it should do something at higher frequencies. Not sure a bit of overshoot is a terrible thing either as it settles well. As it's the ear that decides, have you listened to it with th...

What does it look like with the 320mH jobbie in PSUD?

Re: what are you doing ?

Back from Castleton and what a fantastic part of England. We've never done a walking holiday before and what a fabulous area it is. Did all kinds of walks and visited Chatsworth gardens as well.

Great project Ray and fantastic build as usual. Efficient projects do not seem to be what this place is about :)

Re: what are you doing ?

For the first time time in over 4 months we left town and the never ending list of jobs and drove to Castleton in the Peak District for some relaxation, walks and doing not a lot. If there's any "must see" outings, open to suggestions.

Re: 833A (GU-48) Amp

May have mentioned this before. If you got ht of <1000v, you can use hirschmann 1000v rated 2mm shrouded plugs and sockets.

If you keep the lt on the same chassis as the valve, no need to have connectors for high current, only mains and regular kettle cord connectors.

Re: Symmetric Reichert 300B push-pull

Thanks - I think I need to dust off Spice and model this thing (last used it in 2015). I thought those coupling cap values looked a little on the low side, and I'm not sure anyone's actually built it - looking through the DIYaudio thread now. Lynn has posted a number of variations to his Karna ampl...

Silicon is bad for you on all sorts of levels ;) Glad it's singing again and on AC no less so nice and simple and way less heat.
