I have the complete 250ti Jubilee network diagram and service manual. I want to share with you guys, but problem is that it was scanned to PDF files and I have since coverted it to a word doc. which I can't attached to this forum. Pls share some light to this so all 250 owners can convert their network to the charged coupled network of the jubilees.
Cheers
Thanks also, great!!!:thmbsup:

complex Jubilee network explained
Reference the schematic in post #5.
Starting with the UHF. The series biased capacitor pair C25/C27, the parallel inductor L7, and the series biased capacitor pair C29/C31 form the high pass ~ 18 dB / octave roll off filter for the UHF transducer. The resistor R11 in series with the inductor L7 fine tunes the DCR of that inductor to 0.9 ohms. This technique is used to affect the knee of the curve. In the figure below green is with R11 in the circuit and yellow is with it removed. R12 and R13 provide ~ 2 dB of attenuation.
