Restore a Marantz 2275 for me

[freax]

Hi, I live in Australia and would be welcome to some helpful advice on where I could get components for such an old beast.

I'm considering restoring a pretty good condition Marantz 2275, I've heard it play and it sounds just fine, except for every now and again it generates some crackling, no doubt one of the many components which have reached and exceeded their useful life expectancy...

So I've decided to start a list of components to purchase, first off is capacitors, But I've already hit a snag, the two main filtering capacitors, both rated at 13,000uF at 55 volts with package dimensions of 51mm W x 70mm H.

They don't exactly have a modern counterpart, closest i can find is a 15,000 uF, so its clearly different to what I've got available today.

My first question in regards to the replacement capacitor is, is it a close enough drop-in component or will the rectifier be overly stressed enough to warrant upgrading? a Toshiba 6C3.

Also will voltage drop significantly or is there no trouble in this reguards?

In addition to that, is there anything else I should be concerned about, I'm not exactly an electronics expert, I'm just starting out infact, this is my first real restoration project..

The main goal of this restoration project is to bring it up to at-least working condition and maybe towards modern specifications, without too much loss in the original tonal quality, however no doubt a lot of the resistors will be in terrible condition, swaying out of value, so that will be the next step..

By the way, a schematic/service manual scan would be greatly appreciated.

Thanks in advance.
