Anyone compared 6922 Sovtek & Electro-Harmonix


In Audio Research Preamps?

Alan,
Amperex "GOLDEN GLOBE"? I must be missing something. I know there are Amperex 6DJ8/ECC88, 6922/E88CC, and 7308/E188CC with "ORANGE" globe logo. I've never heard of "Golden Globe" Amperex. ;-P

And I have several hundred of this tube type from Amperex in my collection.

Skipped the Russian tubes all together, they just suck the life out of the recordings. I had just plugged in some 80's Rusian 6h23n into my LS-25 and they sounded flat and murky.

I think the Electro Hamonix 6922 tubes sounded pretty darn good for the price. But in a preamp that operates in pure Class A, they don't last very long and that is their achilles heel.
I wish the JJ E88CC was a better tube. Also unreliable and they become noisy in short order.
I was told by the previous owner of my Symphonic Line tube pre-amp that he had rolled several different kinds of tubes in and out of it, and that despite trying tubes significantly more expensive, the EH 6922s sounded the best in it.

So that's what I'm using, but I'd be interested to know of anyone's experiences with other tubes in this pre-amp.
