Post subject:  Panzerholz experience?
I’m restoring a Panasonic SP10 mk 1 that a friend gave me about 10 years ago in inoperable condition (though it did come with a virtually new SME tonearm). I’ve been reading about plinth designs specifically for the SP10 on line, and virtually every article I have read suggests using either a single sheet of Panzerholz , or a constrained layer plinth using Panzerholz as the middle layer. One of the recurring themes is the cost, finding it in the US, and the difficulty cutting, routing and machining it. Does anyone here have any experience with it? Can you address the issues that I just mentioned?

It seems this guys has some in precut sizes: https://www.usaudiomart.com/details/649 ... ztankwood/
We used it in the shop I used to work in for fixtures in complex glueing and assembly jigs. Honestly we only used it because we got a bunch for dirt cheap. It is incredibly dense stuff. We machined it on a big commercial cnc and even that took plenty of time with freshly sharpened bits.

Uggh. And I only have a router, jigsaw and circular saw. I read that it takes pure carbide tool to cut. Thanks for the link! Upon review, it looks like his biggest size is 12” by 28” or thereabouts. I’ll need at least 2’ in width.

Although an acoustically dead plinth is important don't forget the platter itself. The platter is actually more important to control acoustic breakthrough as it directly impacts what the cartridge is sensing. Cartridges are dumb and don't know the difference between what is cut on the record or what is being transmitted to it through the turntable and arm. Additionally -- replace any small-value electrolytics on the PC board with WIMA pulse caps. A 10-ufd WIMA drops right in the pin holes of a 10-ufd electrolytic. I've attached some photos of my Denon overhaul.

The photo of the platter doesn't show it well enough but the open perimater was filled with potting compound and the center detail is lead sheet with static balance weights.
