Is this preamp mod to reduce gain advisable?

I have an expensive preamp and have this option from the (small) manufacturer to do this to reduce the gain:

" re-wire the input transformer, which would give a 6dB drop in gain. It is fairly major surgery (requires some cuts and re-wiring on the PCB) but it can be done."

Would you do this, or is it too much risk?

Thanks.

6db is not a large change in gain. I doubt that it would be worth the risks of problems arising, or effects on sonics or resale value.

Thanks for the opinion Al. By the way, that's quite a hand-picked system you have there, very impressive. And congrats on the Ulysses speakers; I heard the the Daedalus RMa a few years back and have not forgotten how nice they sounded.

I want that Tandberg deck of yours, if it is better than my Nak682ZX.
And, yeah, forget about those 6db, not worth it.

You might try Rothwell attenuators. My own preamp has quite a lot of gain and the Rothwells give me more room on the volume control and I think, a slightly quieter connection to my amps.

too little info

Are you talking about a transformer on the phono input or the power transformer but the latter doesn't make much sense?

Which preamp?

Why do you want to reduce the gain? I agree that the closer you operate any volume control to wide open the better but what is your goal?
