Advice for mounting a TT shelf on a wall

@4krowme 

Am I correct in assuming that half way up the wall may be another room node?

As I've got older I find the optimum height is high enough so you don't have to bend over when placing records on the platter, and also such that you can look at and clean the stylus comfortably - for me that's about hip level. Forget about room node for height  - bit OTT in my view.

Mount it away from the corners of the room.

This is a must to consider because of low frequency feedback. A corner can be a bass trap. This happened with my wall shelf and it was a pain to get rid of.

Mount it where it’s comfortable to use or you will stop using it. I agree with not putting it in a corner, but other than that, I don’t think it’s that critical unless you have a very large system played at loud volumes. 

Before mounting play some heavy bass songs and place your hands on the wall where you think you might mount the TT and just feel the wall vibrate. Move your hand around and mount where the wall doesn't vibrate as much

IMHE the advice given here is solid. I have wall mounted my turntable for the past two decades after trying various other isolation systems that failed to prevent foot falls and other environmental effects. Hard to see in my system pictures but I'm using an oversized Target PS-1 wall mount shelf which I have modified as follows:

• Weather stripping along the wall facing surface to provide further isolation from the wallboard;
• Heavy duty stainless steel screws with washers inserted between the screwhead and the inner frame to provide the strongest possible bite into the studs;
• Herbies Giant Gliders facing upwards to support the shelf instead of metal points/spikes that are standard;
• Symposium Svelte Shelf (19" X 21") replaces the particle board shelf under the turntable. 

This has worked extremely well for me and is highly recommended for those who can find a Target PS-1 on the used market. My shelf is mounted so that the stylus is at eye level when I am standing. This takes it out of the way of prying hands and also allows me to adjust and setup the table with ease.
