Preamp Deal of the Century

5AR4 rolling.

I have had a Cortese for about 5 months now and needless to say I think it is wonderful.

Two day?s ago the power supply rectifier tube failed (5AR4), well it took me 2 days to get hold of a replacement and yesterday it arrived. What a change, a slight mains frequency hum I had has now reduced by half but more importantly records sound much better. I can only describe it as a blacker background.

I have already tried rolling the 6922 and 6SN7 but the effect of replacing this rectifier tube was more profound.

What experience does anyone else have of changing this tube.

Don't get the enthusiasm over this thread. Speakers are the most important factor in the electronics chain. Yet people seem to love their preamp's the most...then amp's it seems....then speakers.
Hummmm...maybe I should go buy 5 or 7 preamps and place em all around the room for a killer multi channel music system. Cool

Roy,

Agree totally! Have you tried 5V4G yet? Different flavor IMHO. Also, have you tried rolling the regulator tubes (I tried Tungsol 5881, GEC KT-66 Clear and smoked bottle, metal Kenrad 6F6G with good results).

Exertfluffer,

Does anybody here posted that preamp is the most important factor on the chain? Who? Where? If so, It's his/her choice isn't it?

If you do not get the "enthusiasm" on this thread per se, why bother participating in the first place?

What's the matter, did someone offended you here?

I cannot understand why you have to comment like that on something that people enjoy.

Go ahead and buy those additional preamps (7 isn't it?). At least it is your decision and if it makes you happy, then good for you and nothing else matters!

I agree with you. I am even more enthusiastic about my Soundlab speakers.

Hello,

Thanks for the recommendations,

A friend emailed me a couple of days ago and recommended a Mullard GZ34 as a rectifier.
I have one on its way to me now.

I will certainly look out for the tubes you have recommended.
