I am in the process of fully restoring a Marantz 2270 receiver that I've owned for almost 8 years. Restoration is not new to me. I have done restorations before on several stereo components, but never a Marantz receiver. This is my first! (I did restore a Marantz 250M power amplifier which now sounds completely amazing! But I digress...)
What started this Marantz project was the fact that my left channel was dying and making strange noises. I isolated the problem to the left channel Power Amplifier Board and decided to rebuild all of the components on both boards including the capacitors, transistors and diodes. I figured why replace one part when I could refresh the entire board and give them another 20 years of (hopefully) maintenance free life. So I am starting with the Power Amplifier Boards and will refresh the pre-amp board and others next.
Much to my horror, tracking down parts is not easy for this, and my guess other, Marantz receivers. Over the past week or so, I've spent an enormous amount of time researching replacement parts. As a former electrical engineer, I have some knowledge in doing this. I know just enough to be dangerous. For example, I now use a voltmeter instead of my tongue!
After developing my first BOM, I was fortunate to bump into "Catrafter" on this AK site who was kind enough to review my BOM and make valuable recommendations. Given the enormous effort that went into this BOM, we both felt that sharing this BOM would be extremely valuable to the AK community.
For simplicity, I broke the BOM into two sections; one for capacitors and one for transistors and diodes. I have cross-referenced all of the Marantz parts to excellent replacement parts that can be purchased at Mouser.
Here is the BOM for the capacitors:

I ordered all of the above parts on Friday and hope to get them this coming week. I can't wait to get started installing them!!! I'll update everyone on my progress as I rebuild my Marantz 2270 Power Amp Board with brand new parts!!!
In the meantime, I hope that everyone finds this information helpful and please feel free to share any thoughts that you have.
