Leaky capacitors need replacement?

From what I can decipher from Roger's schematic (which has a series of iterative changes written in pencil on it), BOM, and notes it is an electrolytic power supply filter capacitor, 33 uF/350V. As I said previously, the OP should replace it with the same value.

iF you are in USA i would suggest shipping this superb amplifier to tech at Brooks Berdan in Monrovia, CA. They are very familiar with Music reference and the tech will look beyond this issue and get amp properly cleaned up from leak.

just my two cents, they take care of my RM-9.

if all this seems a hassle, i need an RM-10... dead or alive...

Mine is alive and well loved here so it's not going anywhere.  :)

It's just a little sputtery so I'll get that fixed sometime soon, hopefully locally so I don't have to mail it.

@clio09 has been super helpful and great to work with!  Thank you.

hello shawn3998.....I'm curious how old is the amp?  My RM10 Mk II is 10 yrs olde now....perhaps I should check under the hood at some point.

The guy I bought it from said it was 3 years old.
