What do you think and can you supply these items and how do I proceed to acquire them? Phase Linear 700B, Serial Number 6415.
I have all these parts for you (we have replaced the 180 Ohm bias resistor connected from the Base to the Emitter of Q11 and Q12 with a 150 Ohm resistor in the same location). We also substitute a single 5.1 Ohm 5W resistor for the two 10 Ohm 2W resistors Phase Linear used on the output Zobel Network. This makes things a little simpler.
PM me with your address and I will send them to you. Or you can order them from Mouser, here are the P/N's you need:
(2) 5.1 Ohm 5W Zobel Resistors.....................279-ROX5SSJ5R1
(2) 0.1 uF 630V 5% Zobel Capacitors............75-MKP1839410634HQ
(4) 10 Ohm 1% 1/2W Bias Resistors..............273-10/REEL-RC
(4) 150 Ohm 1% Q11/Q12 Bias Resistors....660-MF1/2CCT52R1500F
(20) 0.33 Ohm 2% Emitter Resistors..............660-MOSX3CT631RR33G
