Tubes for a Conrad Johnson 17LS?

I like the speed and tighter bottom end I get from using Philips JAN 6922's instead of the stock Sovtek's. The soundstage is a tad smaller, but the sound is better overall.

Try Electro Harmonix 6922EH in your 17LS which is now standard in the 17LS2. But if interested in NOS exotics then Amprex or Siemans would probably be worth looking at.

Good Luck!*>)

There's a section of FAQ (Frequently Asked Quesions) devoted to tubes over at Audio Asylum with a LOT of information about 6922s and equivalents. I just bought a quartet of Amperex 6DJ8 tubes (6922 equivalents) and they are much better than the stock Electro Harmonix 6922s that came with my used 17LS2.

You can also play with pairs of tubes, recognizing that tubes 1&2, looking at the four tubes from the front, serve the left channel and tubes 3&4 serve the right channel. I've used Siemens 7308s (another equivalent) in positions 1&3 and Mullard E88CCs (yet another) in positions 2&4 with great success. Still trying to decide whether these sound better than the Amerex 6DJ8s.

Have fun tube-rolling. There are PLENTY of options. Dave

I am using Electro Harmonix gold pin 6922's in my 16lsII and like them very much. I have used Philips, Sovtek and Teslas in the past and find myself migrating back to the EH gold pins.

Dopogue,

Should there be any concern with mixing 7308s with E88CCs (which I believe are 6922s) because of different electrical characteristics? The fact that you're doing this without any issues would obviously seem to indicate that there isn't any problem but thought I'd ask. I had read in a few other places that it wouldn't be a good idea to mix types (6DJ8s with 6922s, 6DJ8s with 7308s or 6922s with 7308s) because they are each somewhat different. Although mixing brands (Siemens, Amperex, etc.) of the same type would be okay and could lead to synergistic results.

Thanks,
Joe
