Manley Chinook SE MK2

@lewm my Chinook, which I believe was the mk1, was really silent. Not noisy at all.  Anyone that had a noisy Chinook, in my opinion, needs to investigate tubes. Unless they consider ear to speaker silence a must. The Chinook was the first tubed phono I used and I would highly recommend it coming in to the $2k club of phonos. 

Tubes are one cause of "noise", but we don’t know what sort of noise was experienced with the noisy Chinook. One reason the Chinook (and the Steelhead) are both exceptionally quiet for "tube" phono stages is that they are not purely tube phono stages, as I have mentioned at least twice. The gain stage is a hybrid cascode where a transistor receives the signal and drives a high transconductance tube (one half of a 6922) via its cathode. This makes for high signal to noise ratio, very high gain, very low input capacitance, and wide bandwidth. The only downside is a highish output impedance, which is obviated by adding a cathode follower downstream. That’s the basic circuit of the Steelhead so far as I can determine without having a schematic. Now, to be clear, I am not saying that the Chinook is superior to the Modwright on other grounds; I have never heard the Modwright, and I am sure it too is very good. You pay your money and you take your choice, as the saying goes. I’m only saying that the Chinook is unlikely to be rejected on account of inherent noise.

I chose the Steelhead for its capacity to handle more than one tonearm input and both MM and MC cartridges (actually two MCs and one MM), and for its adjustable input parameters. I think I made mine better by upgrading the output coupling capacitors and the phono load resistors.

Updates?

@theflattire I've had the Modwright 9.0x for 2 weeks now.  In my opinion it's a step up no doubt from the Chinook. It's dead quiet and enjoyable to listen to.  Honestly I think it needs more time but I'm finding it very engaging and extremely smooth.  No harshness or unwanted nasties. Just very musical. Great details, depth and holographic.  Eventually I'll send it in for the T upgrade. 

Thanks

I just put in some Mullards and are liking them. Reflector 6C45s I think are better also. Happy listening!
