Leaky capacitors need replacement?

It’s a Music Reference RM-10 and he should use the exact value for the replacement. I can't remember the brand that Roger used, we may still have some lying around, but the Nichicon’s pointed out by George are a good choice and should fit inside. They were one of Roger’s favorite capacitors. As for getting someone to put them in any competent local tech can do it.  

If you have some extras I’d love if you could send a few to me.  I may have found one or two local techs who might be able to do the work.

If this is a DC blocker, I question whether the lowest impedance capacitor is the best choice. That means more high frequency noise is passed through. Thoughts?

No- it doesn't work that way. Actually though if this is a DC Blocker as it appears the voltage only need be 16 volts not 350.

@clio09 is associated with service of these amps. Tony, can you confirm that this is the DC Blocker circuit?

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...
