My Joule also had a phase button so the mono recordings would also be in phase phase at the same timeNot sure, IME there is more to it than just summing up L+R when converting stereo to mono...I have heard several different methods of converting stereo into mono side by side with a true mono recording and the result was (more or less depending on what method) markedly different than a true mono recording being played back.
There is a phase shift on which stereo relies that you cannot make go away when adding up signals.
A second tone arm and cartridge for the odd stereo record will be added.
Since this is the DIY thread I will share a picture. Made by yours truly. Even did the engraving by hand..I'll admit that the thought crossed my mind that the pre amp had a toggle for dim-witted listeners, of which there are plenty to go around both in a pro (how ever pro is defined) and audiophile environment
OH boy I gotta follow this thread!I promise to upload loads of pics when the beast arrives...it's a huge cabinet weighing a LOT so getting it home is a project in itself. First thing to do is to discuss (and negotiate) a bit about that beauty and some paraphernalia like a Gray Arm and a Fairchild 225a or similar, and a few rare records...I cannot believe it yet...
Many years ago the mono seed was planted, hearing a good TT with a good cartridge and a single speaker in an old School Gym....recently I heard mono again...and was blown away by its energy, directness and musicality, one less hurdle
soundMUSIC does not have to overcome...
Here's my DIY Lenco-based turntable with a mono cartridge on a highish mass Pioneer PA 70 tonearm and a Soundsmith stereo cartridge on an air bearing linear tone arm. My phono stage has 2 MC inputs and 1 MM input (and a mono switch). The mono side only gets used about 20% of the time, but it sounds great.OH boy I gotta follow this thread!
I just completed round two of upgrades on my Lenco. Round one was a new idler wheel, vibration damping of the pan, new sapphire bearing and PEEK bearing plate. Round two further upgraded the bearing to a longer/more precise housing and copper mat.Nice Lenco project!
A Lenco project was my initial start, as finding a 16" TT is not that easy....so I found a Lenco L75 and cleaned it, relubed the motor and got it running really smoothly (one of the previous owners never undid the transport screws) and I was ready to kick the project to upgrade it with all the bells and whistles off once the Audio Server project is done...and now this beast suddenly comes along.

Nope, we're still working on it, plus it will likely premiere at ETF first once it's ready (in case you refer to the phono stage) We will need to figure out quite a few equalisation curves, RIAA was only implemented universally well after the 60-ies. I already have more Vinyl using a DIN curve than RIAA.Marcel, have you posted a schematic for that one?
I know what you mean, certain material is not available or only in poor quality (much rare stuff is digitized by the French national library but their catalogue seems to have suffered dearly over time), it's the main reason I'll add the RCA TT as especially mono recordings seem to be of too little interest for the Qobuz' of this world. (totally understandable)It certainly sounds like it! It's the first time I could imagine being totally satisfied with a digital-only rig. Except for the music that's not on digital, that is.
Are you the same ACHiPo that has been on Audiocircle for many years? Just curious since I recognize the name.It certainly sounds like it! It's the first time I could imagine being totally satisfied with a digital-only rig. Except for the music that's not on digital, that is.
