Additional Kenwood Modifications ZL4AI found on TS-940 #6038687
- Amateur Service Bulletin 909 where C12 6,800uf 16V changed to 5,600uf 25V
- U05B diode from +ve C3 [diode cathode] to +ve C6 [diode anode],
- 22K 0.25W [measures 21.58K Ohm] resistor from junction R1- R2- D3 cathode - Q1 emitter – R3 to ground foil. [the same as suggested by F5VIM Mod 1]
- 4.7K from ‘Base of Q2/C5 across 2 legs of VR1 to junction of ‘Q7 / R7’.
On reverse of Board Component
- 472 pf ceramic capacitor to +ve C3 to anode of D1 is C2 mounted on back of board. [ note C1 & C2 both measured 5.7nf]
22к в моём случае припаян к коллектору а не к базе Q1 как я ошибочно написал.
