This is a great opportunity to be with MartinT again.
Thanks to David Brooks for telling me about this forum.
I'm sure you all know about me, but if not I'll post a 1,000 words tomorrow !
Onwards and upwards guys !
Dave

Good evening Dave, we haven't crossed paths in quite some time. I hope you are well?

Hi Chris, thanks I am very well indeed.
Especially pleased to find Martin and David here.
I'm working on the optimum fidelity of mono LP's right now. Just bought a Leader 5834 Stereo Audio Vector Scope so I can "see" what is happening.
Can't wait for the new Beatles mono LP's direct from the original master tapes.
Dave

Hello Dave and welcome. It's been a long time! That sounds like a hell of a project. What do you hope to achieve?

Hi Martin
It's great to be back !
What I hope to achieve, is the results that a true single coil mono cartridge gives, but using an ordinary stereo cartridge. It is not just an urban myth that a mono cartridge sounds better than a stereo cartridge with the amplifier switched to mono.
I have all the standard reference books, and all the AES notes, the internet is useless at this, and they all talk about "compatibility" not "quality"
Take for instance Nat King Cole "Love is the Thing" LCT 6129 produced in 1957, not to be confused with the stereo pressing SLCT 6129. Played in mono with a mono cartridge the image is truly outstanding. Play it with a stereo cartridge and in stereo, and the mono image is all over the place. Play in in stereo with the Luxman amp switched to mono and it doesn't sound right.
I have a first pressing of the mono Beatles "With the Beatles" on the way, and it will be interesting to compare it in all three modes against the re-release stereo version from the 1978 Blue Box set.
The vector scope allows me to see what is happening, and early vale preamplifiers had different ways of dealing with mono and rumble, hence I'm researching a forgotten art, or is it ?
This could deserve it's own topic ?
Regards
Dave

That sounds like a rather interesting endeavour.
Do you think the majority of the difference is in the playback or in the chain leading up to producing the recording? Was that side of things done in true mono? I guess playing around with mono tapes might give some clues.

Hi Chris
It's all of that and more. Good point on tape, I have a fully restored RS1500, I'll get the mono tape too, thanks !

I sold a load of mono tapes a couple of years ago - they're most commonly available on 33/4 inch per second. If you want faster, then the prices get a bit racy too!

Very interesting, Dave. I've known that mono-ising a stereo cartridge's output is not the same as listening to a mono cartridge, but I've never really understood the mechanism of adding the 2 x 45 degree groove information electrically not being equal to a mono coil picking up the same information.
Do tell us more and start a thread in Source Components if you wish!

Well, I'm at a very early stage and looking for input from others. The vector scope only arrived yesterday and the Beatles first pressing is not yet here.
But the Nat Cole is a revelation ! So more later.
Any chance the mods could take this all out of this section, so it's only my introduction/who am I; into a new one entitled " When is mono not mono ? "
Thanks
Dave

Welcome Dave
I've compared stereo and mono early Beatles albums. The mono has it by some distance
