Preamp Deal of the Century

Hi Gang,

I spoke to Mick and he personally prefers the 6SN7 setup in the Cortese so I am going to stick with that. I have 2 pr. of Tung Sol round plates and some other 6SN7's that I will use in the Cortese when I get it.

Mondie,

PX4 tubes are normally for power amps whereas 101D are typically used on pre-amps. 101D is very microphonic and hard to obtain. According to Mick, he has found a way of using the PX4 to transfer the sound from 6NS7 with perfection (very stable and great-sounding, too!). See the link below for a blow-up PX4! Cheers, Kenji

Slowhand,
.
Now look for some Philips Miniwatt GZ34's and EL37's and a pair of reasonably priced WE 350b's and you are set for the line stage.
.
On deck is some work on the phono stage if you have an interest.
.
From what I have been told, you are in for more than a treat with Mick's latest iteration of the Cortese. It is supposed to be quite an upgrade even from the earlier Cortese models.
.
Let us all know how you fare with your tube rolling and eventually when your Cortese arrives.

Thanks Ongkaku,

Mick emailed me today to say the pre is on the way and that it definitely has the TJ PX4's. Just got my power amp back from repair today too after being 4 weeks without music, there is some serious listening to be done next week when the Cab arrives. Mick in his latest email said the PX4's were - "Better sound, quieter,lower output impedance- they really are fantastic"

What more could you want :^)

Cheers

Hi Larry,

I am using a Phillips Miniwatt metal base GZ34 in the rectifier position. What brands do you recommend in the EL37 and can you tell me how tall this tube is? I have a height issue on the power supply in my rack. I just recieved a pair of Rogers 6F6G's from Ecclectique. He told me that they come within a hair of the sound of the WE350b's. I have never heard the WE350b's, but I can tell you that he has never steered me wrong. I loved these tubes from the very first note of music. They are very detailed with good dynamics, a huge soundstage and very good resolution of the music. I also use GEC KT66's. In contrast, the KT66's are warmer with a little fatter, but well controlled bass. I like the KT66's for some nice slow jazz. My favorite thing about Mick's preamps is how you can "voice" the sound to your liking or mood just by changing tubes. God, I love this hobby! Just a note, my nieces husband is a musician and after hearing both the KT66's and the 6F6G's he felt that the 6F6G's came a little closer to the sound of real instruments (especially guitar).
