My local tech, who is great, and has been doing this over 30 years, says he will work on anything but a 70's Marantz. Just thought I'd mention this before you take it apart.
Marantz 2270 overhaul
My first piece of audio gear was a Marantz 2270. As it happens I still have it, and plug it in from time to time. It still sounds better than some Best Buy gear, but it's getting a little more veiled than it used to and just seems to need an overhaul. I could just check and replace the caps and resistors and polish it, but I'm thinking of making some changes.
For one, I may actually upgrade the caps. Does anyone have any suggestions? Has anyone already upgraded the caps in this era of Marantz receiver?
I'll probably change out the binding posts. It's got the tiny and rather fragile, thumb operated pin slots. I've got other preference, but it seems like it would be easy enough to switch these to barrier strips. Any thoughts on other options for binding posts?
I'd also like the bypass the startup relay as this doesn't get used every day, and the relay never works when it's been sitting idle for a few months. Does anyone have any other suggestions for tweaks to the design?
I'm also planning to build a new hardwood case for the receiver. I've got the original case made from partical board with a veneer. It's in decent condition, but I enjoy wood-working, and could make something really nice. Any suggestions for the wood? Appearance is a large part of the motivation, but I'd like to at least somewhat consider vibration/isolation when considering materials.
