Manley Chinook Owners Tube Rolling

I posted last time above that if the chinook is laid out like the steelhead, then the gain tubes are the pair of tubes nearest to the centerline of the chassis looking from front to back. the cathode follower output tubes are to the left and to the right respectively of the gain tubes in each channel. I hope that’s not too confusing. And if it is ask manley  or your tube dealer.

Johnss, where can I have the caps replaced, does anyone know a manley qualified tech in So. Cal?

you'll have to find a tech in your area. The replacements are Nichicon XY series film and foil. The originals from manley are metalized film.
you can buy the parts from digikey.com

It takes 2 min to change the parts, hard part is all the pre-disassembly work first.

forgot to add the other thing that makes a huge improvement is replacing the metal film load resistors with Vishay VSR metal foil types. You will measurably drop the noise floor by at least 6db. 
@rbtstock , if you contact me off line, can send you plenty of pics.

One other thing. I've done a bunch of rolling in my Chinook.  The stock Electro Harmonix 6922s are very good. The amp was voiced with them per EveAnna 's tech Chris.   

Even though I roll tubes like crazy, I do admit that EH 6922s are a quiet tube.  They really don't get enough credit.  

I'm ready to roll after I understand how the machine sounds stock.  I try to keep an open mind because I never really know what I will like.  I've used inexpensive reissue tubes to great effect, and have found pricey NOS not that great (even when tested and from a great seller).  It always depends.  

If funds are not an option, I'd buy 2 6922s of 3 different makes so you can experiment.
