DIY wood tube dampers

76.87.201.57

I have been listening to Telefunken ECC83 smooth plate tubes and found it to have a bit too much of a good thing in terms of lushness, billowiness in upper-mid/mids.

I then tried the original teflon ring HALO tube dampers, which robbed too much sparkly life. Tried a DIY metal ring damper, which reduced the billowiness quite a bit but added a bit of artificialness. Tried spring-loaded tube cage/cylinder, but again was too much damping.

The current HALO III tube dampers look promising, but they are out of stock.

So I did what I had to, which just about struck the right balance between not robbing too much life and retaining enough lushness while enhancing clarity and detail.

SILICONE O rings low on the tube for less effect. Adjust up for more dampening. Many hardware stores have.
Enoch is valid !
Placement of HALO tube dampers is critical, it's wherever the getter is. Nt - Geoffkait 08:03:49 07/26/24 (0)

"but again was too much damping"

Please help me understand. You are looking for just the right amount of vibration induced distortion?

  sure, short answer is yes.
  I do believe dampers' material/design affects both the amount and character of microphonics being manipulated though. Rubbery/elastic dampers kind of sound well, rubbery and soft and straight metal rings sounding, well a bit "metallic." IME and YMMV of course.
