ODS tubes

[mingus]

What tubes (GE, Phillips, Mullard, etc.) match up the best with an ODS? Do Fender style/spec tubes work best or are there other (preamp and power amp) tubes or values that one should consider to get the best voicing?

I've only done limited testing but I've found that for preamp tubes, V1 and V2 EH tubes seem best when I compare JJ ECC83 and ECC803, Sovtek, and a few others. For the PI I like the JJ ECC83 best. For power tubes I've tested WingedC, Sovtek 5881/6L6GC and JJ's. In my 6V6 amps I've tried EH and JJ. Hands down winner for 6V6 is the JJ, the 6L6 types are all fine, but I had some rattling problems with the WingedC's. Suprisingly I like the Sovtek a lot.

5881's can only support plate voltages of up to 400 volts, right? did you measure the plate voltage when you used the sovtek 5881's? I'm just curious since I was about to buy some Tung-Sols

I am curious about that too Frank.
Hopefully someone who knows will answer.

A Sovtek 5881 is not a "Real" 5881, and will actually handle 500 volts very gracefully. A "Real" 5881 will handle a little over 400 but not much. Keep in mind that if you run your screens around 300Vdc you can actually put close to 700V on a Sovtek 5881.

My current fav's in the ODS are:

1. NOS Chinese, Gray or Silver plate
2. JJ ECC83S, but only certain ones in both v1 and v2
3. GT 12AX7M in V1 but not V2
3 Tung-Sol 12AX7 v2 not v1
4 EH 12AX7 in v2 not v1

In thePI I usually use a JJ, an EI if I can find one, or a NOS 5751.

For 6L6's I do like the TAD short bottle, the Winged C, and The Reflektor Svetlana's.

EL34's I'm JJ's all the way.

I run Telefunkens in the pres and RCA black plates for the power tubes.

Thank you Funk.
I have a few of them laying around so i`ll give them a try in the Dlite.

That is actually some kind of Russian Military Spec Tube, they are quite stout!
