Buying a used Oracle Delphi Mk_ ?


Any comments on what to look for and/or to avoid in a used Oracle - or whether to look for or to avoid a used Oracle in the first place? The idea would be to pay a modest price and then to upgrade gradually as the budget welcomed, enjoying the music in the meantime.

Our system hasn't been complete in over a decade, as we moved around too much to 'do it right': A humbly exquisite little modified Dynaco 70 in triode is all there is of it at present; in the past it included a Walker turntable with Audioquest (which we thought were listenable under the circumstances) and Spika T-60 speakers (which we adored). Thank you all for any input you think relevant.

I'm wondering about Arthur Salvatore's statement, in his 'Recommended Components,' that the entire 1980's/early 1990's Delphi-s were difficult to set up properly ('meaning no wobbling'), which is critical in optimizing their sound: Does anyone know where, say, the Mk III falls in this categorization? - or any personal experience with this difficulty (or not) of set-up with the earlier models?
I used to own a MK3 and if you know how to set it up, it is not too hard. Oracle provides a tool to setup the suspension. I find this easy to use BUT further fine tuning is requred to make the setup perfect.

When the Delphi is setup correctly, you can bounce the TT via the spindle while the TT is playing and it WILL NOT mistrack...that's when it is setup up correctly.

All 3 springs will bounce together in sync and will not affect tracking.

IMO, the ET toeanrms and other linear tracking like the Airtangent are NOT ideal to be used with the Delphis as they are very heavy. I know there are stiffer springs for the TT but they just will not work properly.
Oh, I forgot to mention. If you find a used Delphi, make sure the motor works properly, smoothly because there is no replacement parts for it.

Usually they last a long, long time. Soned and look wise, it is one of the greatest tables available out there.
Genesis is absolutely correct on all points. Any Oracle set up properly will track incredibly well. And yes you can ceate an up and down motion from the center of the clamp where the platter will travel 1/2" up and down and not skip while playing a disc. This is a perfectly set up Oracle, and not very hard to do. Unlike a Linn that you can spend an afternoon fine tuning, and a month later do it again. I would use an old cart and a Foreigner album for the half inch test, and put it through the obsticle course (note; you are exercizing the springs, not crashing the bearing). Then mount your good cart and fine tune if necessary. Once set up right, I've rarely ever had to make an ajustment. You do need a good tone arm as well... Tom
I can't tell which model Oracle I have. What appears to be a serial number on the bottom of the platter draws a blank with the folks at Oracle.

If anyone has a photo of any of the Delphi series, please help.

I would like to know where to begin with upgrades.
