Marantz 2275 phono stage

I getting real close to going vinyl for the first time in 25+ years and was wondering how the 2275's phono stage stacks up. I frankly don't see myself buying a separate phono stage but would still like to know if the Marantz has a decent one. I guess if it's anywhere near the sound of digital (which blew me away with the Marantz) I should be O.K., thoughts anyone?

You might try posting your question over in the marantz forum, you might get more of a response. I personally don't know.
 
Legal,
I've found the Marantz Phono pre's to be pretty good. I'm using one out of a 2250B that I put in an enclosure as a stand alone preamp for my turn table on my surround system. The 2275's appears very similar to mine. I would however, replace the tantalum input coupling caps with some film caps of the same value. The board is designed to take either type and I think the films sound much better.

I think you will be pleasantly surprised at how good it will sound with a descent turntable and cartridge.

I have/had a number of Marantz and the 2275's phono sounds very good. I used it with a Marantz 6300 TT/Shure M97XE. There is "alway" something better but the 2275 is a great sounding, all around reciever.
 
Thanks guys and believe me I know firsthand there's "always something better" but in this case the Marantz will have to be "good enough".
 
The 2SC458 is highest-failure low-noise small-signal transistor in the history of audio!!!!

What goes wrong with them is that they leak like a sieve, and this produces noise and a shift in operating point.

Every one of them should be replaced.

Thanks, Fred. The 2SC2240 is the drop in replacement, then?
Are the ones from MCM Electronics the real deal, or should I purchase them elsewhere?

I have had a number of 2SC458 in vintage electronics go noisy or fail. Any time I see a 2SC458 I suspect it as a source of trouble. I notice that Renesas makes 2SC458 and the 2SC2308 that seems to be a direct replacement. Are the newly manufactured 2SC458 also bad?
 
A question for Fred Longworth: Are there any other 70's era transistors that are known for failing like the 2sc458 and should be replaced? I have a 2275 and a 2230 that could use an update (the 2230 was recapped, the 2275 hasn't been done yet).

What about the following transistor #'s? Any known issues?

2sc828
2sc829
2sa493
2sa494
2sc1000
2sc1327
2sc372

Diode 1n60

Thanks,
