STF to STFM

[+Mitch]

So I was thinking about adding a RF modulator to my 1040STF and picked up the large RF modulator from B&C. Before I soldered in the modulator I wanted to verify that was all that I needed to do. After checking an online schematic it seems there are quite a few more components that need to be added back to the motherboard. Unfortunately, the only schematic that I could find was a bit muddy so I'm not 100% sure if all of my parts are the correct values. Can someone with the later STFM motherboard or maybe a service manual check the values and verify that they are correct?

 

U38 - 74HC74
Y3 - 3.579545
L52 - 3.3uh (or 5.5uh?)
Q8 - 2N3904
Q9 - 2N3904
CR10 - 15v69 ?

C98 - 2.7pf-10pf
C99 - 8.2pf
C123 - 470pf
C128 - .1uf
C131 - 470pf
C132 - 100pf
C140 - 220pf
C141 - 1000pf
C142 - 1000pf
C143 - .022uf

R98 - 10K
R99 - 22K
R100 - 1K
R101 - 2.4K
R102 - 18k
R104 - 1K
R120 - 2.2K
R121 - 2.2K
R122 - 100K
R123 - 100K

 

Thanks to anyone that can help.

I'd like to know where B&C got their RF mod from, I was told that atari only made them for the Euro markets (though i did hear a story that atari did make a small batch for the US market)

I believe they were sold in Canada.
