superstar360fm pb010ab parts missing

Post by ANDREWB »

Hello everyone.
I decided to get back into radio and bought a superstar 360fm with a PB010AB board. it has a TA7222 audio out IC with a hole burnt in it.
That's not a problem but it has a few missing bits around the chip as well, I wonder in anyone could give me the values please?
C168, C169, C172, C173, R423, R424

Failing that, where could I find a hi-res circuit diagram please?

Thanks in advance
Andrew

Hi CH25 and others, could anyone tell/show me where the little black wire that's soldered onto the TA7222 attaches to on the board please?

Hi Everyone.
With your help WE repaired it, works fine. :clap:

Next job is a refurb of my homebrew linear, I built it years ago, been hanging around on my "to-do" list after I repaired the radio. It's 3 of PL519's (valves :shock:) in class AB1, needs 4w of drive for medium smoke, used to be good for 200w
