Hi all, I'm just in the process of finishing to put together an original hybrid design (MOSFET AB output stage). Unfortunately I've run into a bit of an issue. I first built the sand output stage and wired it up directly to the RCAs to test for background noise. It was dead silent in both...

Hi all,   You may have seen my other thread, on modding my amp, but I think I've come round to starting over as I should be able to find the dosh to do something sensible.    I'll just preface this section by mentioning that while I would really like to buy and own a torpedo, the amount...

Well, I've finally finished my CK2III and it's now time to turn my attention to my valve project that started life as a starving student. (Today it runs off dual linear power supplies 24V and 52V, with a CCS plate load 1mA per dual triode). However I get the feeling that it isn't running at it's...

Hi all,   While the original Starving Student was an incredibly high value for money amp, it is fair to say that since disappearance of 19J6 and the standard tube becoming the 12AU7 it has lost some of it's bang for buck, with most 12AU7s costing well over $10 for a decent tube. Since...

I've spent a fair amount of time over the past week running various simulations with regards to constructing such a buffer with no output blocking caps and I have to say that I'm struggling due to the threshold voltage of mosfets - I haven't got a vbe multiplier to work properly yet. I chose...

Ok, I'm a picky person - not so much when it comes to audio quality, but when it comes to various background noises.   I recently finished building my CK2III and have been very impressed with it, however I have a few background noise issues.  I'm going to enumerate them in order of...

HI,  I've posted in the recommendations thread several times and have also spent a long time over the past few months researching. I'm getting stuck though and the person who's gonna be buying me new cans wants to know what I want reasonably soon. I'll go through what I want out of these cans...

I'm thinking of attempting this for my next project, but there appears to be very few resources on the subject. I keep coming back to the same site, which doesn't seem the most reputable, however I expect the guy just copies the schematics out of some old book.   3 different ways of going...

Hi all,   I have just purchased parts to build this amp (12au7 variant) after discussing it at some length with KimLaroux in the dedicated thread.   This is going to be my build log. I'm going to do a few things slightly differently with making of this amp:   The left and right...

Hi all,   Having lurked around for a while I'm starting to get some more music kit ready to go with me to my dorm. Currently I use SRH440 unamplified when I'm away or through my Marantz PM6004 at home (or just speakers when at home). However I will soon be spending more time at the dorm and...

Hi all, first post here, but I often visit just to read.   I bought these headphones on amazon last year (october time), and was pleased when I managed to snag them for under 70€. Well I'm sad to report that they no longer work properly. The right hand cable going from the headband to the...
