tubes for Jadis JP-200

The manufacture date is 1999. The manual says it uses EF-86 and EL86 tubes in the power supply and ECC88-MC, ECC83-Phono and ECC83- linestage.

I have another idea to share with you, a tube mixing strategy that I learned from a consultant at the Audio Outlet/CSA Audio, Mike O'keefe.

Put your NOS tubes in the first line stage socket (front of preamp to the left) and use two more widely available, and likely less expensive, tubes in the second and third sockets. Try the Telefunken matched with two Electro-Harmonix, an Ei with two Electro-Harmonix, or Telefunken and two Eis. Each combination will change the balance somewhat but not the character of the unit.

This system also works for the phono section. However, the NOS tube should be placed in the last socket at the rear of the unit. I have used this strategy with great success during my re-tubing of several Jadis preamps over the years. It is a cost effective way to listen to different brands in your unit before making a significant financial commitment!

With regard to the power supply, I have used GE, Mullard and Telefunken 6CW5/EF-86 tubes, and Ei, Mullard, Electro-Harmonix and Telefunken EL-86 tubes in the power supply with good results.

Good luck!

Agree with every one. Telefunkens have a special magic in the JP-200. Have had the JP-200MC since 1995 and had it updated at the factory in 2007. Still believe it is the best sounding preamp I have ever owned or heard. The best tubes have always been Telefunkens. Mine has all Telefunken 803S. Also agree you should avoid any mods to Jadis equipment. Had one done on the JP-200 and it took away everything that makes the JP-200 the wonder it is. Recently heard the new ARC Reference 40th Anniversary pre and was struck by how much it reminded me of the JP-200.

The 5751 (preferably RCA or Sylvania black plates) substitutes beautifully in the pre for the 12AX7/ECC83. Has slightly less gain but add a sense of ease to the sound. Use it in place of the ECC83 in my JA-80s and prefer it to the ECC83. While on the JA-80, for the best sound of all substitute a 12SN7 for the ECC82/12AU7 (you will need an adapter). The 12SN7 is far more linear than the 12AU7. You can also substitute the 12AX7 for a 12SL7 (again you need an adapter). The difference is not quite as dramatic as the 12AX7 is more linear than the 12AU7, but the sound stage becomes wider and deeper. Recommend it.
