Garrard 301 restoration project

The machining time for Panzerholz is epic, so don't expect that option to be cheap. I'd go for a material that's naturally well damped and acoustically homegenous in all directions, which means that energy is dissipated consistetnly, rather than being reflected between layers. My recommendation? Chipboard - people tend to sneer at chipboard, but it's actually a nice material in the acoustic sense (not to be confused with MDF).

Hugo,

Yeah I guess Panzerholz would be expensive but I see as my final destination, I've looked long and hard at various designs materials and I think this could be what I'm looking for. My other alternatives are Bentonite which is even more expensive or even a sandwhich or differing materials i.e. Panzerholz+Aluminium which would probably be even more expensive. So, it's a compromise bewteen cost and accepting a small decrease in material performance. I've still got the rest of the valve system to pay for.

Heavily contemplating a Bob Cusworth plinth. Just had a pretty in depth chat and this could be the 301s final plinth and my Birthday pressie for this year.

Panzerholz is not that difficult to work with , given proper tools. I have used Panzerholz in my plinths, for years. It is more difficult than Baltic Birch ply, yes, but not terribly so.

Hi Chris,
your plinths are really beautiful, congratulations!

Thank you..

Bentonite and polyester resin is easier to work with than Panzerholz, with proper tooling, and slightly more versatile. I am integrating it into a new line of plinths.

Another day passes and a few more ideas. I thought about adding discrete vibration control to the 301 but you have to be careful. Too much dampening can cause the music to sound drab and lifeless. So I thought about adding valve damper rings around the 401 bearing spindle housing. I also wondered if pitch stability could be improved on the 301 by adding more magnets on the underside of the platter to update the RoadRunner PSU at a faster rate. Both should be pretty easy to test out and fairly cheap to implement. I'll be adding some thoughts on the new Yannis 420.5 litz tonearm cable.
