RCA,PTK195,CTC195 Audio resistor value needed

[Karl Kvicala]

Hello,
Working On an RCA PTK195 chassis with no audio.Found open R14153
resistoron the secondary side of the power supply, but not sure what
it is. It may be a 10 Ohm but it is burned and discolored.
It powers the B+ for the audio amp.
Let me know.
Thanks,
Karl K

The official PTK195 chassis parts data base shows the following information
for R14153:

Symbol Stock Description Circuit Model Version TypeCode Drawing Notes
R14153 241551 RES MF 1W 5% 470R CHASSIS NSM TL_T A XX90572-180



I would say that its 470 ohms.

Be advised, Per TTT 00-001 Bulletin
No Audio in Tuner Mode, Line inputs not affected
Check U16201 #49 should be Apx 3.9 VDC, not functional will check Apx 7 VDC
CTC-195-197 C-12304 possibly open - Pin # 3 of L12303 (NEAR Pin # 1 of
U16201)
Also Check diode CR12301 - Pin # 1 of L12303

Aggrivating problem but a sure fix, per Thomson.
