1176LN Rev F/G

I placed the some post in the "so much gear..." section. Might have been the wrong place, so I try again here:

I have two blackface Urei 1176LN, one has SN 6567, the other 7448. So I think I have a Rev F and Rev G, I may be wrong. It wouldn't be a good idea to use 'em as a stereo pair, would it? If I'd "downgrade" my G to F by putting the input trafo back in, would it be better then, or is it still a stupid idea?

It would not be good to have one with transformer and one without so you could decide which way you wanted them both to go.
Without the finer details of the versions to hand I would suggest that use in stereo would be successful but may need a spot of calibration to ensure they track each other correctly.

have you opened them up?

If they are indeed a rev f and rev g, I think they both used the b11148 output transformer. the rev g will have a 10k input pot and an ic based (5532) input section. the rev f should have a 600 ohm attenuator and an input transformer. I believe, they are otherwise the same and are both class a/b. (someone correct me if I'm wrong)

They're close, but i would not use them as a stereo pair.

Thaks to both of you. I'll check it out. I don't really need to use 'em as a stereo pair since I already have a few nice stereo comps (and I do a lot of mono work anyway ). So if it would be a bigger issue to match 'em then I'd rather leave 'em.

Don't change 'em.

If you need to "stereo squash" something like a drum crush sub-group, then go ahead and try to use them. What's the harm? I sometimes use dual mono compressors for this kind of thing anyway. If the two channels react a little differently, so what? Maybe that adds to the "dynamic complexity." If they don't track well together, and the artifacts bother you, then don't use them.

I wouldn't strap them across my 2MIX bus, but there are at least a few things that I would be happy to try them on.
