It looks to be some kind of practical joke, probably a subtle way to prime our mind for the return of the venerable Patrick82.
Whoever did the mods used all the "right" materials but applied them to exactly the wrong spots.
start with aluminum foil tape: instead of applying the foil to electrolytic caps which already have a thick aluminum housing, he could have wrapped the foil around the power transformer to form a Faraday-cage to block the magnetic leakage.
ERS paper: the proper way to use it: wrap it around all the transistors to form a tiny ERS tube and obtain the much desired "quantum-tunnel" effect, this is the most effective way of using such precious material; then wrap all the resistors with ERS to turn them into some sort of mini Bybee-bullets. Just imagine, a 313 full of these thing, it will be quite a sight.
Hemp: for vibration dampening and suspension purpose. All electrolytics caps should be tightly wrapped with hemp strings; then add at least 2 layers of ducktape. This will reduce the undesirable "microphonics" effect. Yes capacitors can produce and pick up vibrations.
In the ancient days when magnetic levitation/suspension devices were not yet available, hemp ropes were used for, er, hanging? In the case of 313, the PCB could be suspended with hemp strings, though this is not very easy to implement.
tuning dots: should have been applied on the back of the volume pot and the front of volume knob.
by the way, is there any company making paper-oil signal caps with high purity CBD oil? or emu oil?
heheheheheheheh.
I miss Patrick82.
