2250B Rebuild

[smponcho]

HI Guys,
I'm new to the forum, and rebuilding receivers. This is my first go at real electrical work aside from replacing a few resistors on my Fender DeVille amp and home electrical/splicing wires. I have soldered stuff in the past. I am an engineer by trade, so I understand it, but there is little substitute for experience.

I am starting with the Power Board. I will be detailing the parts that I am using, mostly based on what I find on this forum. All parts used will be documented on this google sheet:
https://docs.google.com/spreadsheets/d/1KYcpwSalCR9JTfPxrBMSnV0hTX0PYtrdLTvZ4DZe66I/edit?usp=sharing
I am very interested in feedback on the components I selected. If you find yourself perusing it and know there are better options, please do not hesitate to suggest a replacement.
Will try to upload some pictures.

I currently have a Marantz 4060 hooked up to my PL530 and really like the sound. That might get recapped after this is up and running.

Also, I have been considering purchasing one of these:

I think I would buy the Pro model, but curious if those specs seem like they would be useful. Sampling rate of 1ms seem ok? I don't know if that is useful for an Oscope. I thought they usually need to be much faster for it to be useful.
The meter version is out now and looks to be the same, just can't handle as much voltage.
Any opinions on these?

Thanks,
Pete

Good luck please keep us up to date on how this goes.
Mine is due for a restore.
The 2250B is a pretty rare Marantz receiver with only a total of only 3717 units made.
Marantz thought a lot of the 2250B and considered it one of their no compromise receivers along with the 2335 & 2275.

That's an interesting Gadget!
I wonder how it compares to a digital O'scope.

hi Pete,

this is wonderful, do you have the parts list for the other boards like the P700?

cheers
