Yeah I don't know why Mike would say that. I've always thought the 5751 could be swapped in with a 55% reduction in gain. Who knows.
I have a bigger problem with my Quicksilver line stage. It has way too much gain and 3 clicks is all it takes to reach crisp listening levels with cd's. I should just try the 5751's in it and judge for myself.
Follow Ups:
Mike's probably just covering his butt (and I can't blame him) in not recommending the 5751's, but the Mini-Mite's circuit design doesn't appear to be anything out of the ordinary, and 5751's are drop in replacements for most 12ax7 based circuits, so it stands to reason that 5751's will work in the Mini-Mites. At least they did in mine.As far as 5751's offering a 55% reduction in gain, if memory serves me there was a slight loss of gain of gain in my Mini's with the 5751's, but it was no where near 55%, so I don't know if the 5751's are going to have all that much gain reducing effect on your linestage.
the mu's (factor) of the 12AX7/5751 (100/45) would not translate that way, you are right. But I would expect an audible gain difference?
I don't want to bug Mike again on the phone. By now he's probably convinced that I want to redesign his Mini and Line Stage! I'm not that arrogant!
It's just that I cannot live with 3 clicks of range on a preamp with cd's. I have not played any vinyl through it yet (Sutherland phono stage), but it's probably fine for that.
I have a few preamps so maybe I'll swap in another one for playing cd's. No, that would be a pita!
If you want to try some 5751's in your preamp to see how they would effect the volume, I've got a pair of GE triple mica black plates that I could let you have for a reasonable price. E-mail me if you're interested.
I have six GE's but not black plates. One of the reasons I'm exploring the 5751 thing is that I want to put them to use. I've had them in my tube stash since the early '90's. Thanks for offering.
