Re: Nothing In Particular

If you get a chance to post some photos it would be much appreciated. I fear that my shed is going to require major structural work soon - although not quite on the same scale as yours. Reading your posts is making me feel a bit less daunted....

Re: Latest DSD Decoder Project

Which I guess is one of the reasons higher sample rates or bit rates sound better?

Re: Nothing In Particular

When I were a lad my dad played cricket in Jersey once a year for his team “The Hampshire Maniacs” we went in a Dacota and my Dad a ww2 veteran told me what a wonderful aeroplane it was. On D day as a seaman he was escorting (destroyer) supplies to Russia. A massive part of the war effort . When wa...

Re: Pete Millett ATEST

Ok, so if the secondary is the bifilar windings, won't the centre tap be grounded in use anyway, so just measure centre to secondary, and then repeat for other phase. I may not be understanding what you are trying to do. I’m trying to minimise the distortion of the push-pull driver stage at the out...

Re: Pete Millett ATEST

I don't think I can change the phase of the output - the two secondary windings are joined at the centre. So there are only 3 secondary leads (primary is the same). So if I swap the two 'end' secondary leads, then output valve 1 will get the signal that was going to output valve 2 and vice versa, bu...

Re: Pete Millett ATEST

Thanks Nick. I was planning to measure the secondary of a bifilar wound 1+1:1+1 interstage at about 70V signal level (140V PP). I was thinking that if I ground one side of the secondary (to suit the ATEST input) then that would throw off the capacitive coupling of the bifilar interstage?

Re: Pete Millett ATEST

I can't believe its 2 years since I built my ATEST and I'm finally getting around to using it.....the years are flying by too fast. BTW, the audiotester website was AWOL for a while but is now up again. I've downloaded the trial version and will get a licensed copy if I get to grips with it. Before ...

Have you tried feeding the output of a cartridge into the mic input and doing RIAA in software?

Re: Something stirs in the Undergrowth

How far away are you from the speakers at the listening position? I use MTMs and I have to be a fair distance from them before they sound really good. Also ear height is fairly critical (but gets less critical as distance increases). If the baffle is inclined, you need to take that into account - yo...

can I ask why does it have to be recumbent?
It has to go inside an existing enclosure - and GZ37s are surprisingly tall....

Or to put it another way, I didn't measure to check it fitted until now....

Re: GZ37 horizontal?

Hi Paul :)
GZ37 it is then!
I'll start a new thread when I've got some progress to show.
