 Hey YouTube, okay, well I've gone and copied this circuit this is From a further on YouTube This is a single side of a 12ax7 Or an ecc 83 And this is from John audio techs Design and I've just copied it exactly the only thing that I haven't got is I've not got the one mic Capacitors I have tried with 820s Didn't really make any difference on the input didn't really make any difference all around so I've got a hundred nanofarads in any way which He said would be okay, but everything else is the same I think I've got that query about is The top of my tube glows now we're no on the other circuit when I put together this thing works and it works great the headphones and But it doesn't work Either it won't work for my phone output. I can't just plug my phone onto the input here and have output You know here It doesn't do anything My phone obviously doesn't give out enough power So Last night I played around. I mean this is what I got at the moment That's what I get as the output We did the scope and it's like We get round about sort of three volts peak-to-peak out lessonable RMS I'm putting in a 1k So I'm a 0.4 volts, but you know that's It's not the sharpest it's not the Most spot on I suppose Well, I can't you know, I can't that there's no way that It would give me a an output to a loudspeaker. It just won't have it at all. It's just not enough going on there And I'm a little bit of a loss because it's quite hard to find 12 o'clock circuits anyway I This I've got some figures here But this isn't from this setup. This is from me rebuild in it last night And they're the values that I used And that gave me a bit better on the output. I got a 5.2 peak-to-peak on the output with an 0.4 going in And this was the same supply voltage as what it is at the moment ignore the zero zero dot one It's supposed to be just 0.1 million 100 million basically And now the figures I had look, you know positive on the NA 6.5 for blah blah and so today I rebuilt it back again as John's And this is what I got figure-wise The input output across this course is same But I don't get it. I don't get it because When I used the I used variable pots last night and I fine-tuned it to a nice sine wave That one's got a bit of a belly on it But I fine-tuned it to a nice sine wave and got the figures that I've got You know on here and then if I turned it up here and gave it, you know some stick Like a vault a little bit over a vault peak-to-peak I could then If I connected the speaker Um, which is basically here. I could then hear a little faint You know the one kilohertz sound But I can't seem to do anything else with it And I have asked but I've not had any sort of responses um and I Oh I suppose I Could have got it right There was one voltage. I don't think I changed. I don't know. I don't know. I'm a little bit of a loss with it I'm not gonna you know stop. I still will persevere but I'm just wondering whether this has got anything to do with it You know at the minute. Well, there was setup that I had last night. I had a gain at 12 I've not worked it out on this at the minute What we got we got 0.4 going in three coming out sort of seven I don't know. I'll have to do it with the calculator um But I'm not sure if this is supposed to be glaring At the top I know it works in the other other setup But that's a completely different thing And I'm just curious, you know, I'm just looking for a little bit of help if anyone's got any input at all, please, you know Give us help. It's uh One of those I'm not a professional. I'm not anything. I'm just an enthusiast trying to know my cannot be internet Anyway, cheers watching Bye
