Manley Chinook Owners Tube Rolling

You just purchased it.

Spend time listening to it, and enjoy it.I've tried both the stock version and the SE. Either way, its a nice unit.

Subjectively, tube rolling can change the sound. Depending your own hearing, it can be subtle or you may not even hear it as an improvement. Power cord may also change presentation.

Had Tube pre Tryin ss now  I wont be changing for a while Just wonderin
if your ears heard big changes I was reading you only need to try 2 and not all 4.Hot Topic:  Anyone change fuses in it

I have to wait for it to break in. On average how many Hrs?

Yeah I wont be using stock cord  Any tips on cord

the best sound I have had from the chinook, was with bugle boys from Holland. quite the musical tube.

the other HUGE improvement you can do with the chinook is replace those loading resistors on the rear PCB. From the factory they are metal film.
Install some Vishay bulk foils there and the noise floor will drop, you will get more micro detail, and imaging will improve.
