Manley Chinook question

It may be more beneficial to demo the unit instead of being concerned with what tube type is in the Chinook. It's essentially a stripped down version of Manleys top dog-Steelhead which is an $8K piece.

I have demoed the Chinook. Its everything one expects from a tubed phono stage.
Quiet, realistic presentation and with patience, can be found near half the retail price here, on Agon.

Near half the retail price? He be a waitin' till the cows come home!

I recived my Chinook in march of this year .After two days of use It became defective and was a REAL problem .  Manley handled the issue and replaced with a new unit . Now that I've run the Chinook for four months,Its Great . The stock tubes are very good ,I would not roll them for 2-3 months until  unit is broken in. It does take time to break them in and you may find these stock tubes perfect. I just put in 4 NOS Amperex Gold pin 7308 that came from Upscale Audio . Maybe Its just me , it gets better ever day, these will be the only tubes I use !
