Something else arrived today, the dynamic next of kin to the Russian TDS-16, though both models of the TDS-16 were Echo and this TDS-17 is Amfiton.
I got these to do a recable on some TDS-16, someone used some massive wiring that was a real pain to place into a REAN TRS jack, it ended up too short. Since these have always intriugued me and the cable is identical including plug and strain reliefs to the Amfiton TDS-15's ( at least the models with the concentric squares logo not the scrolly figure "A" logo ) this will have to do for the Echo TDS-16 recable.
At least it is the military grade copper for what that's worth, and of same time period. Why not. The plug end is odd seems stereo but the spacer looks metal there, will find out when i open them up and i should test that soon. Worst case there the plug end simply needs replacing with a fancy right angle black Neutrik one
Have to say though upon initial listening I sort of don't want to ruin them now. Very high impedance the included manual says 100 ohm, I measured roughly 46 on each channel. From what I can tell sensitivity is 98 on these. Rather really decent sounding. I wonder what they would be like with some smaller HT-21 pads and a tiny baffle mod.
So that's why i posted the pictures here in case anyone wants a cheapo recable to take theirs back to stock on one of their Amfitons.
Give me these over a Grado any day.
Hmmm what to do... I know order another one!
DAVID CLARK PADS:there's been some posts using the Beyer gel pads ( round ), you'd have to search. White with a clear top.
The David Clark ones will need to be flush mounted I don't think there's a flap around the edges to hold them on, which would mean scraping off the stock baffle felt that is adhered to the face of the baffles so the bond is perfect.
Surprisingly they have nearly the same inner opening dimensions as the stock pads!
Here is one of the Air Pillow types from a David Clark headset, grungy since they are a possible project not cleaned up yet.
I assume they would be similar to the gels in size though no idea for sure %100.
Side by side and overlaid for comparison.
