Magical Marantz 22## receivers

Why is it generally accepted that caps in a vintage speaker crossover should be replaced but some how these mid-fi (at best) 70’s vintage receivers seem to get better (and more expensive) with no maintenance. I would love to see someone bench test one of these beauties with the “tube like” sound.

I owned a Marantz 2230 and it was nice.  I liked the flywheel tuner the best.  But when I replaced it with a NAD 3140 my large Advents really came to life.  It was no contest.

Hi Kosst

Sorry that I gave the wrong impression. Now that I look back on the OP, I realize he was talking about the Marantz 22..s. The units that I get in are the entry level Pioneer, Technics and such. Very light weight and low mass. For example I work alot with the Pioneer sx-3400. It's a very simple unit to tune and sounds amazing. Of course I'm using my speakers which are extremely easy to drive.

Yep, I don't use the big stuff, as you pointed out, way to complicated.

I apologize for not being more clear.

Mike, those are the primary candidates for that glue I'm talking about. That stuff is just evil. I'm telling ya, if you care much about those units, you'll get that crap out of there. It's eating your traces. It's eating any leads it's touching. And it's becoming conductive itself. Vintage audio forums are chocked full of horror stories because of that glue. I stick to the Marantz stuff because they never used it and you don't have to get into chemicals and hours of meticulously removing that stuff. It's real easy to identify. It almost has the consistency of that expending foam insulation. Lots of air bubbles. It's very hard and cracks and crumbles instead of having any pliability.

"...And yes they get much better with age."

Seriously? Difficult to substantiate since most don't remember how they sounded when new. I've owned an SX-980 since new and still can't remember...(I do have a good excuse..)

Hi Kosst

The Pioneer SX-3400? Where specifically on this unit? I've been tuning these specific units for many years now without anything failing on any of them. Are you sure they are talking about the 3400?

I'm happy to reinvestigate, I have 4 of these units sitting right here, including one taken completely apart so it will be easy for me to see exactly where you are referring to.

thanks
