Note, I was ONLY discussing ST and Globe 45s. These have a " V " or " W " shaped filaments.

All the EML DHTs have LINERLY spaced ( to the plate - and large ) filament structures, as does the JJ 2A3-40.

I have never done much with EML 45s, but I could " imagine " them, from their filament-plate design, to be superior sounding to the V and W older 45s.

I struggled in my living room with ST and Globe 45 amps for a year, NO MORE !!! As soon as I inserted a JJ 2A3-40, operating as a Type 45 ( 5 K output XFR and only 27 mA. Ia ) my VOTTs came to life and sounded linear in the midrange, on piano, etc.

Next, I will convert to a proper 2A3 circuit !! Man, my 515B woofers, in their top range ( crossed over at 800 hZ ) really " rocked" for the FIRST time in a year !! This VOTT system, as I am configuring it, will become a solution I have been looking for in audio, for a long time !!

Cheers,

Jeff
