I am not buying the Amp SS or tube not working....
From the work i have done on All ESLs.....in these setup of the high frc tranfourmer..With the res. Caps.in front an then caps in the mixer....this sets up a push-back to the amps Tube are SS... Not with this new mod..pulling the res. an cap OUT....this is OVERCOME...now i have a pr of 50watt amps driving my set today....thay have NEVER sounded so good as with this mod..before the mod...i could not get the speakers play with 500watt amp... like thay sound with 50watts ...gofig
But however all a esl is Bias...heres a way to test an get the right bias on Any ESL...
put a 2ohm 20 watt res. in the neg input leg of the base tranfourmer... then setup you speaker like you play them get you bias set like Dr. west tell all to do then play cds an the after 10 min...tuch the res.. if the bias is low the 2ohm res well be hot...if all is well the res. well just be worm...
this has work for me for years....the res. was put in to the Acoustat to help with the base tranfourmer overlode..the res get hot not the tranfourmer...Play my setup loude... 2ohms get just worm.....goodluck
