When the almost extinct carbon anode 6080 valves needed replacing Glenn modified it to take carbon anode 6336 valves doubling the power to 20w. This entailed a re-build with extra transformers and Rhopoint non-inductive resistors in key positions. The lid was cut to aid cooling.
They have 16 ohm silver voice coils.
Shielded magnets with earth drain lead.
They were built by Massimo Piantini of Max Research in a collaboration with Yamamura Be using Japanese paper, the proprietary secret black cone-doping compound and slow bake process.
The Loth-X are the best-sounding unmodified full-range drivers ever with beautifully machined frames, stiff cone-doping giving a pistonic movement (no folding) and high quality speaker terminals etc. 104db to 108db sensitivity – horn cab dependent.
Flat 8 ohm and extremely rare as were not sold separately from speaker cabs.
