JohnnyG 7 Posted April 7, 2024 Posted April 7, 2024 Looking forward to sharing knowledge and ideas. I’m retired EE with a passion for Phase linear Amps. Some day would like to own either 700 II or Dual 500. Bought a 400 series I and II many years ago (1990’s) Both blew fuses so needed output transistors. Could find the PL909’s do used any old non To3 the local shop had. Kept blowing fuses after a while. Got smarter as I got older and ordered M15024’s mixed with PLs. Finally went to all 12 15024 in each amp which resulted in better stability. Tried to bias the amp and shorted/exploded a low Ohm resistor across the back of the T03 connector with the VOM probe. Replaced it and now waiting to unbox it all after moving and starting again. Oh well! 7
