Thanks a lot again I will search for the relevant post in the thread for sure For now it is just an idea because i feel bad about disposing this marvel of a unit. Kind regards, gino

Hi thank you very much indeed for your very helpful advice. Then it is done I will use it as a line stage only (my very and only obsession) with a much smaller cap at the output like 10uF and put the board in a new bigger enclosure I also think to use a stepped attenuator in place of the...

Hi thank you very much indeed for your kind and valuable reply I read somewhere that even order distortion can be nice not so odd order one And i know of many well received preamps using fets (like Conrad Johnson for instance but also the old Mark Levinson)... maybe this could be the best...

hi what about starting a separate thread on "before 2012 serial no. L30 rescue project" ? i feel very bad about disposing it Maybe the dc leaking issue could be solved with a dc blocking cap at the output ? i have no clue about how to solve instead the ESD issue Or just using one part of...

Hi if to get a good amount of 2nd order distortion is the goal there could be a much easier way to obtain it. I am not an expert in electronics but a one bjt single ended no feedback line preamp shoud provide a distortion spectrum very similar to this one under review. I mean should...

hi i will check with amazon but I don't have much hopes Yes it was new thanks a lot gino

hi i would sincerely thank you all kind Guys for the very valuable advice I just bought an updated one The seller promises to send a serial 2012xxxxxx or above unit I already bought an upgraded mains transformer that I intend to use I want to use it mainly as line stage I was shocked by its...

Hi thank you very much indeed. As i understand there are still old units sold do i have to look for serial no. 2012xxxxxx and above ?

hi i am attaching the serial no. of my unit I read through the thread but i got lost I need some kind advice 1) is there any doable fix that could prevent any damage to the unit ? like replacing for instance the case with a non metallic one ? or using a plastic pot ? 2) in the use as line...

Thank you very much for your kind and valuable reply. But it seems to me weird to look for speaker cables with the section of a water hose that end in a hair thick voice coil. By the way i followed some DIY discussions about replacing headphones cords. In some they are very very thin. There...

https://www.stereophile.com/content/quad-esl-63-loudspeaker-measurements not perfect SWs i agree but quite like-looking ... i guess taken by a microphone with signals travelling through the air

Speaking of cables for speakers i can't help but notice how thin a woofer's voice coil wire "normally" is. :oops: (i understand that some high end woofers have quite thicker coils). I don't have a precise datum of its gauge and length but if we talk about possible bottleneck for the current...

Thanks. But measure what ? i said listening because it is in the end what we do. Issues in bad digital recordings are very evident. I wonder if they listen carefully to what they produce. They have multimillion equipment ... what are they doing ...

Hi i think you are very right. It could be a result of overprocessing used for producing digital masters. There is a very simple way to check that ... to make a decent digital copy of a high quality analog tape and compare the original to the copy on a high revealing system. If the copy...

absolutely.
