Posted by tyu on April 18, 2012 at 10:59:31:
Thanks for your input on the Sound of this type of setup Ralph....
I posted diff ESL tranfourmers setups years back as i had a pr of SoundLabes A1s..
After owening Acoustats for years an then going to the A1s it was a Dead short...for most of all the tubeamps an even the Krell KSA 250 i have...It never sound like a otl but the A1s were old ...An sounder funky
Anywho...I pull all the crossover out... An pull the center tap off the earth an the bias 0 of the high an low tranfourmers .... An grounded one end of the tranfourmers secdary winding to only the bias 0 ...Same end on bouth high an low Tranfourmers....So this mint the back stater was at the bias 0 only no earth just the bias 0....An then driveing the full winding on just the front stater...You no were the coating an bias are.....Less phase-shift...an got the best sound ever an was lot ezer to drive...lot of fun....But some one had too much money ...so i let him have the A1s for some of it ...There Still a lot of work to be done with ESLs
An OTLs....goodluck
